Solid Carbide Head Brazed into Steel Shank Radius Cone Shape Non-Ferrous Zirconium Nitride (ZrN) Coated SL Burr Bits for Die-Grinders

Please or

The Non-Ferrous (NF) flutes are designed for cutting all non-ferrous and non-metallic workpieces such as aluminum, zinc, plastic, wood, etc. The uniquely aggressive cutting action provides little to no chance of plugging the flutes. The steel shanks are ground, which sets them apart from our competitors. The solder joints are clean, with no excess solder gaping out from the sides between the carbide bud and the shank.

Applications:To be used with air or electrically driven hand die-grinder with a typical collet mechanism or knee mill with an air-driven spindle speeder such as an Air Turbine product. Use of a quality spindle speeder may greatly improve performance of miniature tooling.

Warning: Not to be used in conventional Routers

Excellent for cutting:

  • Aluminum
  • Brass
  • Bronze
  • Copper
  • Zinc
  • Plastic
  • Wood
More sizes, shapes & types available upon request.

Benefits of Zirconium Nitride (ZrN) Coating

  • Creates a harder and tougher cutting edge, allows for a prolonged cutting edge life and helps to prevent the build-up of material in the flutes while cutting
  • Have the tendency to run/spin much faster than an uncoated tool
