Milwaukee 1/8" RED HELIX Cobalt Drill Bit 5-Piece Pro Pack 48-89-2355

HARD METAL DRILLING DOMINANCE

The Milwaukee 48-89-2355 1/8-inch RED HELIX™ Cobalt bits are engineered for the mechanical contractor and fleet manager who demands maximum consumable ROI in high-stress environments. By utilizing a specialized Cobalt alloy, these bits maintain structural integrity and cutting-edge hardness even when subjected to the extreme thermal loads typical of stainless steel and cast iron drilling. The mechanical design focuses on heat dissipation and core strength, ensuring these bits survive the toughest jobsite penetration cycles where standard oxide bits fail.

• / QUADEDGE TIP™ geometry decreases heat buildup at the cutting face for 15X longer life compared to black oxide alternatives.
• / VARIABLE HELIX™ design transitions from 35° to 15° to facilitate rapid chip evacuation and prevent material clogging.
• / 135° Split Point Tip provides an immediate, precision start that eliminates bit walking on curved or polished surfaces.
• / ENHANCED TAPERED WEB™ significantly increases the internal core thickness to minimize bit breakage under heavy lateral load.
• / 3-Flat Secure Grip shank ensures the bit remains locked in the chuck, preventing slippage during high-torque drilling operations.
