Precision Twist Drill 5995593 Drill Bit Set 26pc A-z

Product Description

The PRECISION TWIST DRILL 5995593 is a 26-piece jobber length drill bit set covering the full A-through-Z letter drill size range. Each bit is manufactured from high speed steel with a bright, uncoated finish and ground to a standard 118-degree split point angle. The straight shank design is compatible with standard drill chucks across a wide range of corded and cordless equipment. Built to ANSI specification under the Series R15P designation, this set is sized and balanced for general-purpose metalworking as well as multipurpose drilling applications. The set ships in a metal storage case that indexes each bit individually for fast size identification on the job.

This set is intended for use in metalworking and general-purpose trade applications where the full letter drill size sequence is required. Letter-size drills are commonly used by machinists, pipefitters, and maintenance technicians for tap drilling, reaming prep, and close-tolerance hole sizing in ferrous and non-ferrous materials. The jobber length format provides the balance of rigidity and reach suited to bench drill presses and handheld drilling operations in both shop and field environments.

Installation Notes

Install each bit fully seated in the chuck and tighten all three chuck jaws evenly before drilling. Ensure the workpiece is securely clamped before applying feed pressure. Use appropriate cutting fluid when drilling hard metals to extend bit life. Inspect each bit for wear or chipping before use and remove any damaged bits from service.
