Description
The RT 100 HF is a self-centering, high penetration rate drill, created especially for nickel alloys. The new "HF" style geometry improves tool life, while the brand new TiAlSiN (titanium aluminum silicon nitride) coating withstands abrasive applications. Inconel drilling tests reveal a 35% increase in tool life, due in large part to this new, multi-layer coating that we call nano-Si®.
