Milwaukee 27/64" Cobalt RED HELIX Drill Bit 48-89-2324
MAXIMUM HEAT DISSIPATION FOR STAINLESS AND HARD METAL DRILLING
When drilling into stainless steel or high-tensile alloys, heat is the primary enemy of your cutting edge. The Milwaukee 48-89-2324 27/64" Cobalt RED HELIX bit is specifically engineered to combat thermal breakdown with a high-performance cobalt alloy that maintains its hardness far beyond the limits of standard black oxide. The variable helix design transitions from an aggressive 35° angle to a 15° exit, ensuring rapid chip evacuation to prevent chip welding and friction-induced dulling during deep-hole applications.
- / 135° Split Point allows for immediate penetration on hard surfaces without the need for a center punch.
- / Variable RED HELIX™ geometry optimizes material removal rates while minimizing heat buildup.
- / Cobalt construction provides up to 10X the service life of standard bits in extreme metal applications.
- / 3-Flat Secure-Grip™ shank prevents the bit from spinning in the chuck during high-torque operations.
