Types of Metal Cutting Circular Saw Blades

Metal cutting circular saw blades come in a variety of sizes and shapes to meet the needs of the application they are being used for. There are two basic types, hand saw blades and power saw blades. While there are many different types found within each category, they all generally share common characteristics.

Hand Saw Blades: These are typically smaller in size than power saw blades but offer finer cutting performance – suitable for making intricate cuts in thin metal or angle cuts on tubing. These small blades can be used without any special equipment or prior experience, making them an ideal choice for DIY projects or small jobs that don’t require high-power tools.

Power Saw Blades: Designed to be used on higher-powered circular saws, these blades offer faster and more efficient cutting of thicker materials and longer cuts with little effort from the user. They come in a variety of sizes, teeth per inch (TPI) counts, and materials depending on their intended use as well as the type of metal being cut. Generally speaking, you will find larger diameter blade with fewer teeth per inch count being used on harder metals while smaller diameter blade with higher TPI count is suitable for softer metals such as aluminum or brass. Additionally power saw blades may also come with specialized coatings such as diamond grit which help increase exhaust life when cutting certain metals or abrasive materials such as concrete or brick.

Carbide-tipped Circular Saw Blades

Carbide-tipped circular saw blades are constructed from two pieces of steel that hold a carbide-tipped edge in place. This construction allows for a sharper cutting edge and longer life for the blade. Carbide-tipped blades usually have between 8 and 24 teeth per inch, with larger blades typically having fewer teeth per inch. Although carbide was once rare and expensive, it is now produced in large quantities, making these saw blades more affordable and accessible.

They are generally used to cut through materials such as steel, aluminum, brass, iron and plastic, but can also be used to cut softwoods or hardwoods with a finish. The advantage of using a carbide-tipped blade is that it lasts longer than other blades without becoming worn or dulling quickly due to the harder cutting surface.

Applications of Metal Cutting Circular Saw Blades

Metal cutting circular saw blades are typically used in the transport, construction, and engineering industries. They are designed to cut through metal with accuracy and efficiency. When used correctly, these blades provide excellent results and safety to users.

In the transport industry, these blades are often used to produce components for vehicles such as car frames and body parts. It is important that the correct blade is selected for the job since a wrong choice can cause injury or damage to materials being cut. Blades used in this sector should have a high abrasion resistance, durable teeth structures, fast speed, stiffness of plates and high alloy content for enhanced cutting performance.

In construction industries, metal cutting circular saw blades may be used on sites with metal materials such as beams or reinforcing bars in concrete structures. Here the blade must resist corrosion from harsh weather conditions and display sharpness for precise cuts with no burrs or debris left behind during operation. Chipping is also an issue with certain metals which requires a robust tooth structure ensure smooth vertical cuts for particular applications such as window frames or trims installation which require clean edges without chipping.

In engineering operations, these blades may be employed when making hollow iron pipes of specific size and specifications due to their ability to cope with materials of different hardness like stainless steel but also soft metals like aluminum. Since it is critical that fan blades are made accurately and consistently due to safety reasons; a sharp circular saw blade able cope with such operations can offer sensitive curves along profile shapes of the fan pipelines at higher productivity levels without getting worn too fast as compared other types of saws like hacksaws or band saws.


Metal cutting circular saw blades specifically designed for woodworking offer several advantages to woodworkers. They are more efficient, quieter and easier to adjust than their traditional counterparts, making them ideal for a range of woodworking applications. Most woodworking blades have teeth that alternate from left to right, providing a consistent cut throughout the workpiece. The quality of the cut depends entirely on the size and shape of the teeth, so it’s important to select the right one based on your requirements. For example, if you want a clean finish with fewer splinters then choose a blade with more and smaller teeth; conversely if you want quick cuts that don’t need a lot of cleaning up then choose a blade with fewer and larger teeth.

There are three main types of metal cutting circular saw blades used in woodworking:

1) Framing blades – these are designed for rip-cutting wider boards quickly into smaller components such as planks or frames. These blades typically have 24 teeth or more and make fast cuts as they require less effort than other types of saw blades;

2) Plywood-cutting blades – these have 20 or fewer teeth specially designed for cutting plywood veneers cleanly;

3) Combination blades – with 18-22 teeth, combination blades can make both rip and crosscuts.


When it comes to metalworking, there are several types of circular saw blades that are recommended for use based on the types of metal being cut. Saw blades that are specifically designed for metal cutting feature an enhanced tooth design and different tooth geometries which allow them to effectively slice through metal material while preventing excess wear and tear on the blade itself.

Some types of circular saw blades suitable for performing various tasks related to metal cutting include:

-Hook Tooth Blades: Hook tooth saw blades feature large gullets and alternating rakers which make them well-suited for slicing through large amounts of material quickly and efficiently. They provide fast cuts with a generally smooth finish, making them a popular option when working with metals such as aluminum, copper, mild steel and bronze.

-Carbide Tipped Circular Blades: Circular saw blades fitted with carbide tips provide superior wear resistance compared to their steel counterparts, allowing them to deliver longer service life when cutting certain metals such as hardened or tempered steel, stainless steel and aircraft alloys. This blade type is preferred in fabrication applications where high speed operation is required.

-Diamond Cutting Blades: Diamond tipped circular saw blades are designed for maximum performance in abrasive materials like ceramic tile, tile grout, concrete pavers and masonry stone. Their ability to resist wear make them ideal for use in the cutting of cast iron pipe supply lines as well as ferrous metals such as stainless steel or mild steel when extreme precision is necessary.

Factors to Consider When Choosing a Circular Saw Blade

In addition to the type of saw blade you select, there are other important factors to consider when purchasing a saw blade for your project. Factors such as tooth design, number of teeth, the material being cut, and the speed at which it is being cut can all influence the selection of a effective saw blade for your job.

Tooth Design: Teeth help define how a particular Saw Blade is used for cutting different types of materials. The typical tooth design used on Saw Blades is referred to as an ATB (alternate top bevel) or FTG (flat tooth grind). For most wood cutting applications, ATB and FTG blades provide excellent results. For metal cutting applications it is usually best to select blades specifically designed for that type of material.

Number of Teeth: More teeth on a Saw Blade will provide a finer finish but may require more time and effort to complete a task due to the larger number of cuts being made from each rotation. A greater number of teeth will also produce more heat, which can degrade its performance if not properly monitored. On the other hand, fewer teeth creates less heat but creates coarser cuts with increased tear-out that requires more sanding or cleanup after cutting has been completed.

Material Being Cut: The material being cut will largely determine which type of saw blade should be used for optimal results. Soft woods such as pine and cedar generally require less aggressive tooth designs with reduced numbers of teeth per inch whereas hardwoods such as oak usually require more aggressive profiles with increased numbers of teeth per inch in order to produce clean cuts without splintering or tearing out around the edges. Metals typically require specialist saw blades designed specifically for those applications or significant loss in performance may result due their higher time constraint requirements that necessitate heavier chip clearance capabilities into produced waste-products in order too maintain safe operation speeds without causing premature wear tear on Saw Blades themselves leading up to an inadequate result in terms lacklustre performance by having unacceptably produced small sized chips at correspondingly lower rates corresponding slower project did completion times than one should reasonably expect from well operating tool set-up; thus providing exact level feedback required during certain operations where close inspection visibilities are couched in necessary outcome criteria thus deciding whether work successfully passes parameterised segmentation tests prior expected wide scale production assembly runs consecutively offered through businesses services provided for chosen degree courses.

Type of Material to be Cut

When selecting a circular saw blade, it is important to consider the type and hardness of the material you are cutting. Typically, materials fall into one of four categories: Ferrous Metals, Non-Ferrous Metals, Wood/Composites, and Masonry/Concrete. Each type of material requires specific characteristics from your circular saw blade to ensure you get the most out of your tool and the best results from your cuts.

Ferrous Metals Ferrous metals have small amounts of iron in them and can be divided further into cast iron or steel (including stainless steel) applications. Blades for ferrous metal cutting typically have teeth made with carbide or similar hard materials such as high-speed steel (HSS). These blades should have more teeth than blades for non-ferrous metals, usually 20 to 24 teeth per inch (TPI), with precisely formed grinding angles on each tooth for improved performance.

Non-Ferrous Metals Non-ferrous metals are those that do not contain iron and typically include aluminum, brass or copper alloys. The excellent heat conductivity of these materials requires saw blades with fewer teeth than those used on ferrous metals so that each tooth can cut away a larger chunk without overheating due to friction. Therefore, blades used on non-ferrous materials can range from 2 to 24 TPI depending on the application requirements but typically encompass 12 to 18 TPI for best results when cutting harder alloys. The teeth should also be made using hardened alloys such as HSS or cobalt steel so that they remain sharp longer and produce cleaner cuts.

Wood/Composites Wood Cutting blades require a different set of characteristics than those for metal cutting applications since woods are generally softer materials than metals . Blades designed specifically for woodworking projects usually have more relatively large TPI figures anywhere from 14 up to 60 depending on what kind of job is being performed because they need thicker edges that won’t tear out the wood fibers during use. Additionally, these thicker edged blades will help reduce splintering when making precision cuts in wood composites such as plywood or MDF board so that you get accurate results every time.

Masonry / Concrete As would be expected for products used in masonry and concrete work such as brick pavers or precast stone panels , most circular saw blades designed for this type of applications will feature diamond coated tips which enable them to breech even the toughest surfaces . The coating helps keep these constant friction producing tools sharp even under extended use , reducing risk damage from overheating . In addition , having a lesser number TPIs – usually 8 – 10 – allows extended life when making uncostly diagonal cuts across concrete surfaces.

Maintenance and Care for Circular Saw Blades

Circular saw blades should be regularly inspected for defects and damage. To ensure sharp and accurate cuts, perform regular maintenance and checks on the blades before each use, especially in commercial and industrial applications.

Regularly check the blade for excessive cracks, gashes, chips or worn teeth. Be sure to also look at the arbor hole and make sure corrosion has not caused its size or shape to change. It is important to keep your blades lubricated at all times so that debris will not accumulate on them. This will help prolong the life of your saw blade while also ensuring that it performs adequately during use.

It is recommended to sharpen your circular saw blades every few hours of use or when replaced with a new set of blades after much wear from previous usage. To sharpen circular saw blades easily and quickly you can purchase a manual blade sharpener which allows you to accurately control the cutting angle. An automatic rule grinder is another option that works off a rotating disc governed by sensors for more precise control over sharpening capabilities. Regardless of which method you choose, proper lubrication between uses as well as cleaning off any dust build-up should be done regularly to maintain blade quality and performance levels over time.

Proper Use and Handling

The type of circular saw blade you select and proper use and handling techniques will determine the life of your blades and the quality of cut. Selecting the right size and type of saw blade for the right application requires knowledge. Once you have selected the right blade, here are a few guidelines on proper use, storage, and upkeep:

Use heavy-duty blades with extra-hardened teeth (usually indicated by a blue mark) on hard materials such as metal. Use sturdy blades with standard or hardened teeth on nonabrasive materials such as wood or plastic. Always be sure to wear safety glasses when using these tools and follow manufacturer instructions when using any cutting device!

Prior to beginning your project, check that all bolts are tight on the machine; if a blade is loose it can be dangerous to operate. Setting up the saw correctly is also important; it should be level, square to the work surface, firmly secured in place, and should move only as intended. Keep guards in place at all times and keep hands clear of moving parts. Make sure your saw’s power switch is always in reach so that in an emergency you can turn it off immediately if necessary.

To increase life expectancy of your tools, never force a cut that exceeds capacity or bind your material against the saw’s fence — doing so causes excessive heat buildup at points which weakens steel or results in blades breaking apart prematurely before they have reached maximum wear potential. Be sure to choose compatible “carbide grade/hardness” for further extended tool life while cutting harder materials such as aluminum alloys or stainless steels (see bed card information supplied by tool manufacturer). Over time dust can cause excessive torque buildup in most cutting machines due to static friction build up; make sure to clean out chips from internal machinery often for better performance!

Cleaning and Storage

As cutting with a circular saw blade generates considerable heat, it is important to allow the blade to cool before attempting to clean or store it. To clean your cutting blade, use a wire brush and a mild soap solution to remove any material buildup. Use caution around the teeth of the blade, as this will be the sharpest area.

Once your metal cutting circular saw blade is dry and free from dust, it should be lightly oiled before being properly stored. Do not store for too long — if you were to leave it unused for an extended period of time, rust could start forming on its surface. When you are finally ready to use it again, make sure you check the condition of your cutter thoroughly – check for any nicks or damage that may have occurred during storage and assess whether all components remain secure. Visual inspection can help detect warped edges and chips in blades which may lead to vibration if left unchanged prior to operating with again.

Safety Precautions When Using Circular Saw Blades

When using a circular saw, safety must be of paramount priority. It is important to take the proper precautions when handling, installing, and maintaining these blades. Some of the following measures should be taken when using a circular saw blade:

-Read and understand the operator’s manual before attempting to use any blade. Proper protective gear should always be worn, including eye protection and hearing protection.

-Inspect the blade prior to use and verify that the teeth of the blade are sharp and in good condition free from chips or other deformities that could cause accidents or burns while making a cut.

-Securely attach blades to arbors or mandrels so that they cannot fly off during operation. -Do not use any tools with broken or cracked saw blades as you can easily endanger yourself and those near you during operation. When changing blades, ensure that all bolts are tightened properly before operation begins.

-Holding materials for cutting firmly in place will help ensure smooth cuts without kickback or binding which can lead to injuries if not properly handled during cutting operations.

Proper Handling and Usage

The proper handling and usage of the metal cutting circular saw blades is very important for ensuring optimum performance and a quality finish. In order to get the most out of your blade and extend its lifespan, take some simple steps:

-Always use a push stick when cutting materials less than two inches thick on a table saw or miter saw. This helps prevent unintentional contact with the spinning blade.

-Before using any saw, make sure that it is properly mounted and aligned. Check both the upper and lower guards to ensure they are secure; the lower guard should not move when the blade is running.

-When changing blades, always wear protective goggles and gloves to avoid any potential injury from sharp edges or flying debris. Make sure to disconnect any power source before replacing a blade in order to prevent unexpected movement of the saw while working on it.

-Use only compatible blades for your type of saw; all blades must have a complete set of teeth, with no broken or missing ones in order for them to work correctly and safely.

-Be sure to read instructions carefully before use, as different colors may denote specialty steam-treating processes such as heat tempering or other treatments that can affect blade performance or safety considerations like spark containment.

Safe Work Area

Creating a safe work area for metal cutting circular saw blades is essential for ensuring the job gets done safely and smoothly. Whenever possible, it’s best to clear the area of any debris or material that can be thrown by the saw blade.

Furthermore, it’s important to use safety clothing and eye protection while operating a metal cutting circular saw – while this may seem like common sense it never hurts to remind workers of safety procedures before beginning a task.

It is also necessary to inspect the saw blade each time prior to use – if there are any visible cracks or damages, do not put the tool in use until repairs have been made. Following manufacturer guidelines for use of power tools should also be observed whenever possible.

Finally, it is always important to ensure that operators properly secure the workpiece being cut; doing so will ensure proper contact between the saw blade and workpiece as well as help avoid injury due to kickback or malfunction.
