Milwaukee 1/4" RED HELIX Cobalt Drill Bit 5PK 48-89-2363

EXCEPTIONAL HARD METAL ENDURANCE

Engineered for the high-demand shop floor where downtime is the enemy of profit, the Milwaukee 48-89-2363 RED HELIX™ Cobalt bits represent a significant leap in consumable metallurgy. By utilizing a high-performance cobalt alloy, these bits maintain structural integrity at temperatures that would cause standard black oxide variants to anneal and fail. The mechanical architecture features an aggressive 35° helix that transitions to 15°, optimizing the chip evacuation path to prevent heat soak during deep-bore applications in 304 stainless or high-tensile alloys.

• / QUADEDGE TIP™: Four cutting edges reduce heat buildup by distributing the load, ensuring the bit stays sharper for significantly more cycles.
• / VARIABLE HELIX™ DESIGN: Accelerates chip removal to minimize friction and prevent bit binding in thick-gauge materials.
• / ENHANCED TAPERED WEB: A thicker core at the base of the flute prevents snapping under high-torque loads, maximizing the lifecycle of your investment.
• / 135° SPLIT POINT: Eliminates "walking" on smooth metal surfaces, allowing for precision starts without a center punch.
• / 3-FLAT SECURE GRIP: Specifically machined shanks prevent the bit from spinning in the chuck, ensuring maximum power transfer.
