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.
