Carbide-tipped Band Saw Blade

Carbide-tipped Band Saw Blade is a high-performance cutting tool suitable for cutting high-hardness, high-wear-resistant metals (such as stainless steel, titanium alloy, tool steel, nickel-based alloy, etc.) and high-density materials (such as composite materials, hard plastics, etc.). Its characteristic is that the tip of the saw teeth is welded with carbide (tungsten carbide), which is more wear-resistant and has a longer life than ordinary high-speed steel (HSS) saw blades, but the cost is also higher.

Characteristics of Carbide Band Saw Blade

Ultra-high wear resistance:

The hardness of carbide (tungsten carbide) can reach HRA 90 or above, which is suitable for cutting high-hardness materials, and its life is 5 to 10 times that of ordinary high-speed steel saw blades.

High temperature resistance:

It can remain sharp at higher cutting temperatures and is suitable for long-term continuous cutting.

Wide range of applications:

It can cut difficult-to-process materials such as stainless steel, titanium alloy, hardened steel, high-temperature alloy, wear-resistant cast iron, etc.

High cost:

The price is 3~10 times higher than ordinary band saw blades, but long-term use can reduce the cost of a single cut.

How to use carbide band saw blades correctly to extend their life?

1. Choose the right saw blade parameters

Tooth Geometry:

Standard teeth (Regular): general cutting, suitable for most metals.

Hook teeth (Hook): large rake angle, suitable for soft metals (aluminum, copper) and efficient chip discharge.

Variable teeth (Variable): reduce vibration, suitable for thin-walled pipes and special-shaped materials.

Tooth pitch (TPI, Teeth Per Inch):

Thick materials (>50mm): 3-6 TPI, to ensure smooth chip discharge.

Medium thickness (10-50mm): 6-10 TPI, balance cutting speed and finish.

Thin materials or pipes (<10mm): 10-14 TPI, to prevent tooth jamming and tooth collapse.

2. Adjust sawing machine parameters

Band saw speed (Cutting Speed):

Hard metal (stainless steel, titanium alloy): low speed (20-50 m/min).

Soft metal (aluminum, copper): medium-high speed (60-100 m/min).

Feed pressure (Feed Pressure):

Avoid excessive pressure that causes saw teeth to break, and let the saw blade cut naturally.

Cooling and lubrication:

Cutting fluid (emulsion, oil-based coolant) must be used to reduce friction and heat.

3. Correct installation and maintenance

Tension adjustment:

Carbide saw blades require higher tension (20-30% higher than ordinary saw blades) to prevent deflection and vibration.

Guide wheel calibration:

Ensure that the saw blade runs smoothly on the track to reduce lateral wear.

Cleaning and storage:

Clean the chips after use to prevent corrosion. Avoid collision with saw teeth during storage.

4. Avoid common mistakes

Wrong pitch: Too low TPI will cause chip jamming, too high TPI will easily cause tooth breakage.

Dry cutting: Carbide saw blades must be cooled, otherwise high temperatures will reduce their life.

Forced feed: Let the saw blade cut naturally to avoid impact loads.
