If you drill a lot of metal and regularly burn through standard bits, the BECOLLO 1/8-inch cobalt drill bit set is a practical value buy. This 20-piece set uses cobalt (5%) high-speed steel (M35) to boost heat and wear resistance—helpful when working in tougher metals like stainless steel and cast iron.

Each bit features a 135° split point designed to self-center and reduce walking, so you can start holes more confidently without constantly re-positioning. The fully ground processing helps create a smoother surface for reduced friction and faster cutting compared with rougher-finished bits.

You get twenty 1/8″ (0.13-inch) straight-shank bits stored in a plastic case, making it easy to keep spares on hand in the shop or in a tool bag.
