Milwaukee 15/32″ COBALT RED HELIX Drill Bit

MAXIMIZED THERMAL RESISTANCE FOR SUSTAINED DRILLING IN HARD METALS

When drilling through stainless steel or cast iron, heat is the primary enemy of tool longevity. The Milwaukee 48-89-2327 Cobalt RED HELIX bit is engineered to combat thermal fatigue through a specialized cobalt alloy construction that maintains its hardness even at extreme temperatures. By utilizing a variable helix geometrystarting at an aggressive 35 and transitioning to 15this bit optimizes chip evacuation, preventing the material buildup that leads to work hardening and premature bit failure. The integration of a 135 split point ensures the bit bites into the workpiece immediately, eliminating the need for center punching and reducing the mechanical stress on your drill’s motor.

• / 135 Split Point Tip starts on contact to prevent walking and ensure precision hole placement in hard alloys.
• / RED HELIX Variable Geometry clears chips rapidly to limit heat buildup and extend the life of the cutting edge.
• / 3-Flat Secure-Grip Shank provides a mechanical lock in the chuck to prevent bit slippage under high-torque loads.
• / Enhanced Tapered Web strengthens the core of the bit, significantly reducing the risk of snapping during deep-hole applications.
