3016016 Cobalt Jobber Drill Bit, 1/4 In. Dia, 4 In. Oal

The Irwin 3016016 is a cobalt jobber drill bit designed for metal drilling applications. This 1/4-inch diameter bit combines high-speed steel with M-35 cobalt for higher heat and abrasion resistance. The 135-degree split point minimizes bit walk and begins drilling immediately, making it well-suited for metal drilling on hardened steel and alloy metals.

Heavy-duty web construction provides strength and durability for tough applications. The heat-treated steel enhances performance under stress, making this bit capable of handling heavy-duty abrasive metal drilling and demanding work conditions.
