This counterbore is equipped with Poly Crystalline Diamond (PCD) tips and an internal bore to allow for varying size interchangeable pilots to be fitted (sold separately), the Poly Crystalline Diamond (PCD) tips enable an excellent surface finish with extremely long tool life. In direct comparison to high speed steel and carbide, PCD tools are exceptionally resistant to wear. In certain applications these diamond tools can exceed the life of an equivalent carbide tool by 50 to 100 times.
Excellent for cutting hard abrasive products such as carbon fibre.
Material: high speed steel shank with fixed Poly Crystalline Diamond (PCD) tips.
