Milwaukee 48-89-2302 Red Helix Cobalt Drill Bit, 5/64 In., 2 In. Oal

The Milwaukee RED HELIX 5/64 In. Cobalt Drill Bit is engineered for extreme durability and long life in hard metal applications. This jobber-length twist drill bit combines advanced materials and precision design to deliver fast, accurate holes in demanding materials—including stainless steel, high alloy steel, cast iron, and standard metals—while reducing the effort required and minimizing heat buildup during use.

Cobalt drill bits are ideal for professionals and serious DIY enthusiasts who need reliable performance when drilling through hard materials where standard black oxide bits wear out quickly. The RED HELIX design addresses common drilling challenges: bit walking, heat damage, slow chip clearance, and premature breakage. This bit stays sharper longer and requires fewer tool changes, saving time and reducing project costs.

Features and Benefits

• Variable Helix Design: The aggressive 35-degree helix angle transitioning to 15 degrees promotes rapid chip removal, limiting heat buildup and extending bit life.
• Precision Split Point Tip: The 135-degree split point tip delivers a precise start without walking, enabling fast and accurate holes across a variety of materials.
• Thunderbolt Web Design: A thicker core than standard drill bits provides ultimate strength and protection against side-load breakage during demanding drilling tasks.
• Cobalt Steel Construction: High-quality cobalt material withstands the rigors of tough drilling applications and delivers up to 10X the life compared to traditional black oxide drill bits.
• Versatile Performance: Suitable for all twist drilling applications, from hard metals to wood and plastics, making it a reliable choice for mixed-material projects.
