3016009 Cobalt Steel Drill Bit, 135-degree Split Point, 9/64 In.

This Irwin cobalt steel jobber drill bit is engineered for demanding metal drilling applications where heat resistance and durability matter. The 9/64-inch diameter bit features a 135-degree split point that begins drilling immediately, minimizing bit walk and ensuring accurate hole starts even on hard, abrasive materials. Whether you're fabricating metal parts, performing heavy-duty maintenance, or drilling through hardened steel, this bit delivers the performance you need to complete jobs efficiently.

Cobalt steel construction provides superior heat and abrasion resistance compared to standard high-speed steel, allowing for prolonged drilling without dulling. The heavy-duty web construction adds strength and durability, reducing the risk of breakage under stress. The M-35 cobalt alloy composition makes this bit ideal for tough applications including heavy-duty abrasive and alloy metal drilling on hardened, heat-treated steel.
