Milwaukee 48-89-2318 21/64′ COBALT RED HELIX™ Drill Bit

Engineered for precision and durability, the 21/64″ Cobalt Red Helix™ drill bit from Milwaukee Tool is a top choice for tackling hard metals, PVC, and wood. Its innovative RED HELIX™ design facilitates rapid chip removal and minimizes heat buildup, thanks to the integrated CHIP BREAKER™ technology, which ultimately extends the bit’s lifespan up to ten times compared to traditional black oxide options. The 135° split point ensures a precise start without walking, while the Secure Grip™ feature and 3-flat shank design keep the bit firmly in place during use. Constructed from high-speed steel, it excels in drilling through a variety of materials, including aluminum, steel, and stainless steel, making it a versatile addition to any toolbox.
