Silver Tungsten Carbide High Purity Solid Carbide Burrs Rotary File Drill Bits

Silver Tungsten Carbide High Purity Solid Carbide Burrs Rotary File Drill Bits are precision-engineered cutting tools designed for demanding industrial applications. Manufactured from high-purity tungsten carbide, these rotary files deliver exceptional hardness, durability, and cutting performance across a wide range of metal and non-metal materials.

• Head diameter: 3–35 mm
• Shank diameter: 3 mm, 6 mm, 8 mm
• Extended-length configurations are available upon request

• Head diameter: +0.3 to +0.5 mm
• Shank diameter: +0 to +0.04 mm
• Total length: ±0.1 mm

The speed at which you use your carbide burr in your rotary tool depends on the material being worked and the contour being produced. It is generally safe to say you do not need to exceed speeds of 35,000 RPM. The table below shows approximate recommended speeds.

As with all drill bits and burrs, let the tool do the work and apply only a little pressure. Excessive force will cause the cutting edges of the flutes to chip away or become smooth too quickly, reducing the working life of your burr.

When using your carbide burr, avoid keeping it stationary for too long. Remaining in one spot will cause the burr to dig and jab into the material, resulting in unsightly marks and surface roughness.

• 100% quality and brand new.
• Can process a variety of metal and non-metal materials, with processing hardness up to HRA 89–92.5.
• In a great part of the work, it can replace the petiole small wheel, with no dust pollution.
• High production efficiency — processing efficiency is several times higher than a file, and nearly 10 times higher than a small wheel stalk.
• High product processing quality and high finish; can process a variety of high-precision mold cavities.
• Long life — durability is 10 times higher than high-speed steel cutting tools and 200 times higher than small grinding wheels.
• Easy to use, safe and reliable; reduces labor intensity and improves the working environment.
• Suitable for processing metal and non-metal materials such as cast iron, cast steel, bearing steel, high carbon steel, chrome-nickel alloy, bronze, brass, ceramic tile, marble, jade, and bone.
