Presenting the Milwaukee RED HELIX 21/64 in. Cobalt Drill Bit, built for demanding metalworking with exceptional wear resistance. This cobalt twist bit combines a rugged alloy with smart cutting geometry to extend life and improve hole quality. Its variable-helix design features an aggressive 35-degree lead that tapers to 15 degrees, reducing heat buildup and stabilizing the cutting action. A precision 135-degree split-point tip starts the hole with accuracy and minimizes walking when drilling through hard metals, PVC, or wood.

Benefits Paragraph: This drill bit delivers reliable performance in tough materials, reducing downtime and rework. The cobalt composition and optimized geometry maximize life and enable faster, cleaner holes across metal, plastic, and wood applications.

Key Features & Benefits:
  • Cobalt alloy construction delivers superior heat resistance and extended life for hard metal drilling
  • Variable-helix geometry reduces friction and aids chip evacuation for smoother cuts in tough materials
  • 135-degree split-point tip provides a precise start and prevents walking on hard metals, PVC, and wood
  • Reinforced tapered web strengthens the core to boost flute durability and overall longevity
  • Up to 15x longer life versus standard black oxide bits, delivering reliable performance for professional metalworking

Why This Drill Bit Stands Out: Its cobalt composition and reinforced core are tuned for heavy-duty metalworking, delivering consistent performance across tough materials. Expect longer service life, fewer re-drills, and cleaner holes that speed up fabrication. This bit is designed to keep pace with professional workloads, helping you finish projects with confidence.
