Precision Twist Drill 091533 Hss Silver Deming Jobber Drill

Product Description

The PRECISION TWIST DRILL 091533 is a high-speed steel (HSS) Silver Deming jobber-length drill bit with a 1/2 inch reduced parallel shank. It features a 33/64 inch diameter tip and a 4 inch depth of cut, with an overall length of 6 inches. The 3-flute construction increases chip evacuation and delivers high resistance to abrasion during extended use. This bit is suited for drilling into steel, cast iron, aluminum, and similar materials in trade and industrial settings. Licensed tradespeople and machinists reaching for a durable, reduced-shank bit for use in standard 1/2 inch chucks will find this a reliable workhorse.

This drill bit is designed for jobber-length applications where a reduced shank is needed to fit a standard 1/2 inch drill chuck while boring a larger-diameter hole. Typical use cases include metalworking, fabrication shops, mechanical contractors, and maintenance technicians who need precise, clean holes in metal components. The Silver Deming style is a common choice when the full bit diameter exceeds standard chuck capacity, making the 1/2 inch reduced shank the practical solution.
