Milwaukee® Shockwave™ Impact-duty titanium drill bits with red helix are engineered for impacts and drills. Designed with a variable helix with an aggressive 35 deg helix angle which ends at 15 deg, the impact-duty titanium drill bits with red helix provide rapid chip removal to limit heat build-up to stay sharper longer. The 135 deg split point tip delivers a precision start and prevents walking for fast, accurate holes. Titanium coating can be used in all drilling applications to give you up to 3X life versus black oxide drill bits.
