Milwaukee’s design features an aggressive 35° helix angle that varies along the flute, ending at 15°. Unlike a standard flute design, this limits heat build-up by providing rapid chip removal and allows the user to get more life out of their bit.
The Shockwave Impact Duty Titanium Red Helix Twist Drill Bits are specifically engineered for use in impact drivers delivering up to 3X Life vs Black Oxide Twist drill bits. Along with Variable Helix flute geometry for faster material removal, a chip breaker decreases heat build-up, and a 135° split point tip delivers a precision start and prevents walking for fast, accurate holes.
The Cobalt Red Helix drill bits engineered for extreme durability and long life in hard metal applications. Used more so in specialty drilling applications such as stainless steel, 4140 and cast iron.
