Milwaukee 21/64″ Cobalt RED HELIX Drill Bit 48-89-2322

MAXIMUM HEAT RESISTANCE FOR STAINLESS STEEL AND HARD ALLOYS

Professional-grade drilling in abrasive materials requires more than just a sharp edge; it requires superior thermal management. The Milwaukee Cobalt RED HELIX drill bits are designed with a variable helix geometry that accelerates chip removal, significantly reducing the heat buildup that destroys standard bits. The 135 split point allows for immediate engagement without the need for a center punch, while the cobalt-infused steel maintains its structural integrity even when pushed to the limit in high-torque applications. This is the essential choice for technicians looking to minimize downtime and maximize hole-per-bit efficiency.

• / Variable RED HELIX design clears material faster to prevent heat-related dulling.
• / 135 split point tip prevents bit walking and ensures precision starts on hard surfaces.
• / Cobalt construction provides up to 10X longer life than black oxide in metal applications.
• / 3-Flat Secure-Grip shank prevents the bit from spinning in the chuck under heavy loads.
