Precision Twist Drill 5995624 Drill Bit Set 29 Pc Hss

Product Description

The PRECISION TWIST DRILL 5995624 is a 29-piece jobber length drill bit set made from high speed steel (HSS) with a bright, uncoated finish. The set covers sizes from 1/16 inch to 1/2 inch in 1/64-inch step increments, giving technicians and tradespeople a full range of fractional sizes in a single kit. The 118-degree standard point angle suits general-purpose drilling in a wide range of materials. Straight shanks are compatible with standard three-jaw chucks on most drill presses and handheld drills. This is a Series R10P set conforming to ANSI specifications and stored in a plastic case for organized access on the job.

This set is designed for metalworking and multipurpose drilling applications in trade and industrial environments. It handles common tasks such as pilot holes, clearance holes, and through-drilling in steel, aluminum, and similar materials. The range of 29 fractional sizes makes it practical for HVAC, plumbing, electrical, and general mechanical work where multiple hole diameters are needed across a single job. The plastic storage case keeps bits organized and reduces time spent locating individual sizes on busy job sites.

Installation Notes

Install bits securely in the chuck and tighten fully before operation to prevent slipping. Always wear appropriate eye protection when drilling metal. Match spindle speed to the material and bit diameter per standard machining practice — smaller diameters require higher RPM than larger diameters. Ensure the workpiece is properly clamped or secured before drilling to prevent rotation or kickback.
