Milwaukee 48-89-2305 Jobber Drill Bit, 1/8 in Dia, 2-3/4 in OAL, Twist Flute, 3-Flute, 1/8 in Dia Shank

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 deg 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.
