Product Description:
Engineered with red helix, the Milwaukee Titanium Bit is an impact duty bit that’s designed for use with impacts and drills. Extremely handy, it has a variable helix with an aggressive 35-degree helix angle, which ends at 15-degrees. The innovative design limits heat build-up to stay sharper longer, while the 135-degree split point tip delivers a precision start and prevents walking for fast, accurate holes. Extremely handy, it can be used in all drilling applications to give you up to three times the life than that of black oxide drill bits.
