Precision Twist Drill 5995632 Drill Bit Set 29 Pc Hss

Product Description

The PRECISION TWIST DRILL 5995632 is a 29-piece screw machine length drill bit set built for metalworking and general-purpose drilling in shop and field environments. Manufactured from high speed steel with an oxide finish, these bits are designed for durability under heavy-duty cutting conditions. The split-point tip at 135 degrees starts on contact without a center punch and reduces walking on hard surfaces. Straight shanks fit standard drill chucks. The set covers sizes from 1/16 inch to 1/2 inch in 1/64-inch step increments, giving technicians a complete fractional range in a single case. Licensed trades and maintenance professionals who need consistent, reliable hole quality in metal will reach for this set daily.

This set is suited for metalworking and multipurpose drilling applications in both residential and commercial maintenance, fabrication, and light manufacturing environments. The screw machine length format — shorter than jobber length — provides added rigidity and improved control in drill presses, lathes, and hand drills where chatter or deflection is a concern. The included metal storage case keeps all 29 pieces organized and protected between uses. This set meets ANSI and NAS 907 specification designations, making it appropriate for shops and contractors who work to published tolerance standards.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using standard drill equipment. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole finish. Inspect bits for wear or damage before each use and replace any bit that shows cracking, chipping, or loss of point geometry.
