Precision Twist Drill 5995597 Drill Bit Set 26 Pc Hss

Product Description

The PRECISION TWIST DRILL 5995597 is a 26-piece jobber length drill bit set covering the full letter series from A through Z. Each bit is manufactured from high speed steel with an oxide finish for improved lubricity and basic corrosion resistance during metalworking operations. Straight shanks conform to ANSI standards, making the bits compatible with standard drill chucks across corded and cordless platforms. The 118-degree standard point angle suits general-purpose drilling in mild steel, aluminum, brass, plastics, and similar materials. This set is packaged in a metal storage case and is sized for daily shop use by machinists, pipefitters, electricians, HVAC techs, and general maintenance trades.

The 5995597 set is designed for metalworking and multipurpose drilling applications in both residential and commercial settings. The A-through-Z letter sizing range makes this kit practical for tap-drilling operations where letter-size bits are specified by tap-drill charts. Typical install scenarios include field service vehicles, maintenance shops, fabrication benches, and service trucks where a full letter series needs to be on hand without sourcing individual bits. The metal case keeps bits organized and indexed for fast identification on the job.

Installation Notes

Installation of drill bits should be performed by a qualified tradesperson familiar with proper chuck seating and drill press or hand-drill operation. Secure the bit fully in the chuck before operation and verify the chuck key is removed before powering the tool. Select the appropriate bit for the material being drilled and use cutting fluid when drilling ferrous metals to extend bit life. Inspect bits for wear or damage before each use and replace any bit that shows chipping, dullness, or deformation.
