Sutton Tools Inox jobber drills are an industrial quality drilling solution specially designed for superior performance in stainless steel. Tailored to overcome the difficult-to-machine material properties of stainless steel, Inox drill bits have a fast spiral, short flute and unique stepped core design providing a smooth and effortless cutting action never before seen. For added wear resistance, these drill bits feature the latest generation Futura Nano PVD coated tip. Inox drill bits have been independently tested to achieve 70% more tool life in stainless steel compared to standard drill bits.
