Precision Twist Drill 5995703 Drill Bit Set 8 Pc

Product Description

The PRECISION TWIST DRILL 5995703 is an 8-piece reduced shank drill bit set in the Series R56 line, designed for metalworking and general-purpose drilling applications. All bits are manufactured from high speed steel with an oxide finish for added surface hardness and corrosion resistance. The set covers a range from 9/16 inch to 1 inch in 1/16-inch step increments, with a uniform 1/2-inch reduced shank diameter that allows larger-diameter bits to fit standard 1/2-inch chucks. The 118-degree standard point angle suits a wide range of common metal and multipurpose drilling tasks. Bits meet ANSI standards and are stored in a plastic case for organized transport and storage on the job site.

This set is suited for licensed tradespeople and maintenance professionals performing metalworking, fabrication, and multipurpose drilling in residential and commercial settings. The reduced shank design is particularly useful when a 1/2-inch chuck drill is the only available tool but larger hole diameters are required. Step increments of 1/16 inch let technicians work through a progression of hole sizes without switching sets. The included plastic storage case keeps bits organized and protected between uses on service calls or in shop environments.

Installation Notes

Installation is performed by machinists, maintenance technicians, or qualified tradespeople using a 1/2-inch chuck drill or drill press. Secure the workpiece firmly before drilling and use appropriate cutting fluid when drilling through ferrous metals to extend bit life. Inspect each bit for wear or damage before use and replace any bit showing signs of chipping or excessive wear. Follow applicable shop safety protocols and wear appropriate personal protective equipment during drilling operations.
