Milwaukee 13/64" COBALT RED HELIX Drill Bit 48-89-2310
MAXIMUM HEAT DISSIPATION FOR STAINLESS AND HARD METAL DRILLING
Drilling through stainless steel, cast iron, or thick structural steel requires a bit that manages thermal energy as efficiently as it cuts. The Milwaukee COBALT RED HELIX™ series is engineered specifically for these high-friction environments where standard high-speed steel bits typically fail. By utilizing a variable helix geometry—starting at an aggressive 35° and tapering to 15°—this bit accelerates chip evacuation to prevent the "heat soak" that leads to premature dulling. The cobalt alloy construction provides the necessary red-hardness to maintain a sharp cutting edge under extreme pressure, ensuring a professional ROI through significantly extended tool life in the most demanding metalworking applications.
- / 135° Split Point Tip: Delivers a precision start on contact and prevents bit walking on hard surfaces, eliminating the need for center punching.
- / RED HELIX™ Variable Flute: Optimized geometry clears material faster to limit heat buildup and maintain edge integrity for up to 10X longer life vs. black oxide.
- / CHIP BREAKER™ Technology: Integrated design breaks up large shavings to reduce friction and further decrease operating temperatures during continuous drilling.
- / 3-Flat Secure-Grip™ Shank: Prevents the bit from spinning in the chuck under high-torque loads, ensuring consistent power transfer and protecting the chuck jaws.
