Milwaukee 13/64″ COBALT RED HELIX Drill Bit

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 geometrystarting at an aggressive 35 and tapering to 15this 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.
