The Milwaukee Thunderbolt Cobalt Drill Bit is a premium metal drilling solution engineered for demanding applications where standard drill bits fall short. This 7/64-inch jobber bit excels at drilling through hard alloys, stainless steel, and tough metals. Cobalt construction provides exceptional durability compared to standard bits, offering up to 10 times the life of black oxide bits in hard metal applications.
The 135-degree split point tip prevents walking and delivers precision starts. The advanced helix design removes chips efficiently, limiting heat buildup to keep the bit sharper longer. The jobber-length design and cordless drill compatibility make it adaptable to various metal drilling needs with consistent results across job sites and workshops.
