5/16" COBALT RED HELIX™ Drill Bit

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, while the 3-FLAT SECURE-GRIP™ shank holds the bit firmly in the drill chuck. 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.
