Milwaukee 19/64" COBALT RED HELIX™ Drill Bit

ENGINEERED FOR EXTREME DURABILITY IN HARD METAL APPLICATIONS

When drilling through high-tensile materials like stainless steel and cast iron, heat is the ultimate enemy of tool life. The Milwaukee 48-89-2316 19/64" Cobalt RED HELIX™ Drill Bit is mechanically optimized to combat thermal breakdown through its advanced Variable Helix™ geometry. By utilizing an aggressive 35° helix angle that transitions to 15°, this bit achieves Rapid Chip Removal™, preventing material from clogging the flutes and transferring heat back into the cutting edge. This design, coupled with the integrated Chip Breaker™ technology, ensures the bit stays sharper significantly longer than standard high-speed steel alternatives, providing a professional-grade ROI for high-volume metalworking.

• / RED HELIX™ Variable Geometry provides rapid chip evacuation to limit heat buildup and extend bit life.
• / 135° Split Point Tip delivers a precision start on contact, preventing bit walking on curved or polished surfaces.
• / Cobalt Alloy Construction offers superior heat resistance, delivering up to 10X longer life versus Black Oxide bits.
• / 3-Flat Secure-Grip™ Shank prevents the bit from slipping in the chuck under high-torque drilling conditions.
