In the cutting operation of metal, wood, non-ferrous metal, plastic, and other materials, tungsten carbide circular saw blades have become the preferred cutting tools of many processing plants due to their excellent hardness, wear resistance, and service life. However, there are many types of tungsten carbide circular saw blades on the market with different parameters. How to choose the most suitable saw blade according to your own needs has become a concern for many purchasing personnel and technical workers.

This article will analyze in detail how to scientifically choose tungsten carbide circular saw blades that really suits your needs from multiple dimensions such as the structural characteristics, selection parameters, application materials, tooth design, brand technology, and common misunderstandings of tungsten carbide circular saw blades.

1. What is a tungsten carbide circular saw blade?

tungsten carbide circular saw blades, the full name of which is tungsten-cobalt alloy circular saw blades, are usually composed of a high-strength steel saw body and tungsten steel alloy welded teeth. Its cutting tooth part usually uses cemented carbide (such as WC-Co, that is, tungsten carbide + cobalt), which has extremely high hardness, high temperature resistance and wear resistance.

tungsten carbide circular saw blades are widely used for cutting:

Non-ferrous metals such as aluminum and copper;

Metal materials such as stainless steel, carbon steel, and alloy steel;

Woodworking fields such as wood, particleboard, and medium-density fiberboard;

Non-metal materials such as plastics and acrylic.

2. Key parameters for selecting tungsten carbide circular saw blades

2.1 Outer diameter (Blade Diameter)

The diameter of the saw blade should be selected according to the specifications of the equipment used. Common specifications are:

Small equipment: 110mm, 125mm;

Medium equipment: 180mm, 210mm;

Industrial equipment: 250mm, 300mm, 350mm, 400mm, 500mm, etc.

The larger the diameter, the deeper the cutting depth, but the higher the power requirement for the equipment.

2.2 Tooth Count

Small number of teeth (such as 24T~40T): suitable for rough cutting, fast cutting, strong chip removal ability;

Medium number of teeth (such as 60T~80T): suitable for multi-purpose processing, taking into account efficiency and precision;

Large number of teeth (such as 100T and above): suitable for precision cutting and workpieces with high requirements for smooth surface.

2.3 Tooth Shape

Common tooth shapes include:

ATB (alternating tilted teeth): suitable for wood cutting, smooth cut;

FT (flat teeth): suitable for aluminum and copper materials, more durable cutting;

TCG (triangular staggered teeth): used for hard materials such as plastics, metals, laminates, etc.;

Wave teeth/W teeth: used for thin-walled materials to reduce burrs and chipping.

Choosing the right tooth shape according to the material properties is the key to ensuring cutting quality.

2.4 Bore Diameter

The bore diameter must match the spindle of the saw machine. Common specifications include 16mm, 25.4mm, 30mm, etc. If the saw blade aperture is inconsistent with the equipment, a conversion washer can be used, but it is not recommended to use it for a long time.

2.5 Saw blade thickness (Kerf Width)

The thinner the saw blade, the smaller the cutting resistance, which is suitable for high-speed precision processing; but too thin is easy to deform, affecting the straightness. It is generally recommended to select a suitable thickness (for example, between 2.0mm and 3.2mm) according to the equipment speed and workpiece strength.

3. Choose tungsten steel saw blade according to the cutting material

3.1 Metal cutting

Aluminum/copper: It is recommended to use a tungsten carbide circular saw blade with a moderate number of teeth and a lubrication groove design to prevent sticking;

Steel (stainless steel/carbon steel): It is necessary to choose super-hard alloy teeth + reinforced tooth back structure, which is heat-resistant and wear-resistant;

Thin metal plate: Choose a tooth type of W tooth or TCG to ensure accuracy and reduce flash.

3.2 Wood cutting

Solid wood: ATB tooth type, fast chip removal and smooth cutting;

Multi-layer board/particle board: Choose a tungsten steel saw blade with a large number of teeth + coating design to reduce tearing and burrs.

3.3 Plastic/Acrylic/PVC

It is recommended to choose a circular saw blade with polished tooth surface and small spacing to prevent cracking, heating and sticking.

4. Consider the matching of cutting method and equipment

Different equipment is suitable for different types of saw blades:

Table saw/panel saw: focus on size and accuracy, choose multi-tooth high-precision type;

Handheld cutting machine: give priority to lightweight and good heat dissipation models;

CNC cutting equipment: higher requirements for saw blade balance, industrial-grade saw blades with excellent dynamic balance should be selected.

The speed and cutting method (dry cutting/wet cutting) of the equipment will also affect the selection of saw blades.

5. Influence of brand and manufacturing process

High-quality tungsten steel saw blades often have the following advantages:

Fine welding process: the welding teeth are firm and not easy to fall off;

Excellent material of tooth tip: wear-resistant and pressure-resistant, and can still remain sharp after repeated re-grinding;

Good dynamic balance: stable operation and low noise;

Scientific design of heat dissipation holes: effectively prevent thermal deformation of saw blades.

It is recommended to purchase from manufacturers with regular brands, good after-sales and processing technology.

6. Analysis of common purchasing misunderstandings

Only look at the price but not the performance: Although inferior tungsten steel saw blades are cheap, their teeth are easy to collapse and have a short lifespan, and the actual cost is higher.

Ignore the matching of tooth shape and material: Different materials require different tooth shapes. Wrong matching not only affects the cutting effect, but also causes the workpiece to be scrapped.

Change the saw blade size at will: Blindly choosing a large diameter saw blade without checking the carrying capacity of the equipment may cause safety hazards.

Ignore the brand and after-sales service: In occasions with high frequency of use, choosing a supplier with technical support and customizable services can reduce the risk of downtime.

As an important tool for modern cutting and processing, the correct selection of tungsten carbide circular saw blades can not only improve processing efficiency, but also extend the service life of the saw blade, reduce the cost of consumables, and increase the yield rate. Whether you are an end user or a factory purchaser, mastering the key factors mentioned in this article can help you find the most suitable one among many saw blades.
