Milwaukee® Red Helix™ 48-89-2305 Jobber Length Drill Bit, 1/8 in Drill - Fraction, 0.125 in Drill - Decimal Inch, 135° Point, Steel, Cobalt

Milwaukee® Thunderbolt® cobalt drill bits are designed for extreme durability and long life in specialty applications. The Thunderbolt® web features a thicker core than a standard drill bit to provide ultimate strength and protect against side load breakage. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. Effective for drilling on curved surfaces, Milwaukee® Thunderbolt® cobalt bits require less effort to drill through stainless steel, high alloy steel and cast iron and are highly recommended for use with portable drills.
