6mm 1/4" Tree Shape Tungsten Carbide Rotary File Drill Bits


Description of Tungsten Carbide Rotary File Drill Bits

Tungsten Carbide Rotary File Drill Bits are tools commonly employed in metalworking for tasks such as cutting, grinding, and shaping metal surfaces. Typically crafted from a mixture of tungsten and cobalt metal powders, carbide is a remarkably hard and wear-resistant material, formed through sintering at high temperatures and pressures.

Aluma cut refers to carbide burrs specifically engineered for processing aluminum alloys. The advantages of carbide burrs with Aluma cut designation are outlined as follows:

  • Hardness and Wear Resistance: The high hardness of carbide ensures the retention of sharpness during machining. This attribute is particularly crucial for processing softer aluminum alloys, contributing to extended tool life and enhanced performance stability.
  • High Thermal Stability: Carbide burrs with Aluma cut designation exhibit elevated thermal stability, indicating resistance to deformation or annealing during high-speed cutting. This characteristic contributes to maintaining cutting surface quality and prolonging tool life.
  • Tailored for Aluminum Alloys: Aluma cut carbide burrs are specifically designed for aluminum alloys, taking into account their unique characteristics. These include the lower hardness, high thermal conductivity, and propensity for chip adhesion associated with aluminum alloys.
  • Reduced Chip Accumulation: The design of Aluma cut carbide burrs facilitates a reduction in chip adhesion, preventing the accumulation of cutting debris on the tool surface. This aids in improving cutting efficiency while mitigating friction and heat generation during the machining process.

How to use the Tungsten Carbide Rotary File Drill Bits:

1. Speed /RPM


The speed at which you use your carbide bur in your rotary tool will depend on the material you're using it.

The contour being produced but it's safe to say you do not need to exceed speeds of 35,000 RPM.

The table below shows some approximate speeds:


Diameter of Burr RPM
3mm or 1/8" 17,000 - 26,000
2.35mm or 3/32" 17,000 - 26,000
6mm or 1/4" 11,000 - 16,500
12mm or 1/2" 8,000 - 12,000
16mm or 5/8" 7,650 - 11,500

2. Apply only a little pressure

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

3. Keep The Carbide Burr On The Move

When using your carbide burr try not to keep it still for too long as this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.
