Platinum Mechanics Length HSS Drill Bit. The Brute Platinum XL Drill Bit is a high speed steel drill bit that is made for drilling materials with high tensile strengths such as stainless steel, titanium, and other hard steels. The drill bit has a heavy duty 135° split point tip for self-centering and quick penetration. The mechanics length bits are slightly shorter than YOUR NORMAL JOBBER BITS to help with strength and rigidity. The three FLATS ON THE SHANK ensure a positive grip in your chuck.
