48-89-2323 Red Helix Cobalt Drill Bit, 13/32 In., 5.12 In. Oal

The Milwaukee RED HELIX 48-89-2323 is a cobalt drill bit engineered for extreme durability and long life in hard metal applications. This professional-grade drill bit is designed to handle the toughest drilling tasks in stainless steel, high alloy steel, cast iron, and other demanding materials where standard drill bits fail quickly. Whether you're a professional tradesperson or a serious DIY enthusiast, this bit delivers the precision and reliability needed for fast, accurate holes in challenging materials.

Cobalt steel construction makes this drill bit significantly more durable than standard black oxide bits, providing up to 10 times the tool life. The variable helix design and split point tip work together to minimize heat buildup, reduce friction, and prevent bit walking, so you spend less time drilling and more time completing your project efficiently.

Features and Benefits

• Premium Cobalt Steel: Built from high-quality cobalt material to withstand the rigors of hard metal drilling applications without failure or premature wear.
• Variable Helix Design: Features an aggressive 35-degree helix angle that transitions to 15 degrees, providing rapid chip removal and minimizing heat buildup to keep the bit sharper longer.
• Split Point Tip: The 135-degree split point tip delivers precision and prevents walking for fast, accurate holes.
• Reduced 3-Flat Shank: The 3/8-inch diameter 3-flat shank provides the reduced shank design for versatile drill chuck compatibility.
• 10X Life Compared to Black Oxide: Exceptional durability makes this an excellent long-term investment for professionals and serious DIY users who work frequently with tough materials.
• Versatile Applications: Ideal for hard metals, but can be used in all twist drilling applications across various materials and projects.
