The Milwaukee 48-89-2307 RED HELIX Cobalt drill bit is made for durability in hard metal applications. It features a variable helix with a 35-degree angle that transitions to 15 degrees, allowing efficient chip removal and reducing heat buildup. The 135-degree split point tip prevents walking, ensuring precise drilling, while its robust design offers longer life compared to standard black oxide drill bits.
This drill bit is ideal for tough applications, providing up to 15X the life of standard drill bits.
