Jobber Drill Bit 9/32'' x 4-1/4'' Cobalt and 20 similar items

Jobber Drill Bit 9/32'' x 4-1/4'' Cobalt High-Speed Steel - IRWIN 3016018 (5-PK) The Irwin 3016018 jobber-length drill bit is a high-performance, cobalt-enhanced HSS (High-Speed Steel) cutting tool engineered for drilling tough, abrasive metals ? including stainless steel, cast iron, titanium, and heat-treated alloys. Measuring 9/32 inch in diameter with a 4-1/4 inch overall length and 2-15/16 inch flute length, this bit features a 135-degree split point that ensures immediate, accurate penetration without ?walking,? delivering clean, precise holes even in hardened materials. The single spiral flute and right-hand cutting direction optimize chip evacuation and reduce binding during deep or continuous drilling. Coated in gold oxide for enhanced heat resistance and lubricity, the bit withstands high temperatures generated during metal drilling ? extending tool life and maintaining sharpness under heavy-duty use. Built with a heavy-duty web construction and M35-grade cobalt steel (5% cobalt), it offers superior strength, abrasion resistance, and durability compared to standard HSS bits. The 9/32-inch straight shank fits securely in drill chucks, drill presses, or magnetic bases for maximum torque transfer. Packaged carded for easy storage and weighing just 0.1 lbs, it?s ideal for machinists, fabricators, automotive technicians, and serious DIYers who demand professional-grade performance in demanding metalworking applications.
