Precision Twist Drill 5995926 Jobber Drill Bit 10 Hss

Product Description

The PRECISION TWIST DRILL 5995926 is a wire size 10 high-speed steel jobber drill bit designed for accurate, repeatable hole-making in demanding materials. It features a 135-degree split point that reduces walking and requires less thrust to start the cut, along with a bronze straw coating that improves lubricity and surface hardness during operation. Overall length is 3.625 inches with a flute length of 2.4375 inches, giving it the reach needed for standard jobber-length applications. The shank diameter matches the drill diameter at 0.1935 inches for a true straight-cylindrical fit in standard chucks. Licensed machinists, maintenance technicians, and trade professionals working with high-temperature alloys and hard metals will find this bit suited to production and general-purpose drilling tasks.

This drill bit is built for use on high-temp alloys and materials classified under ISO workpiece material codes P, M, K, and S, covering carbon steels, stainless steels, cast irons, and superalloys. It fits into standard jobber-drill workflows in machine shop, MRO, and field service environments. The Series HX10-HX15-HX18 designation places it within a family of heavy-duty wire-gauge bits engineered for consistent performance across high-volume drilling cycles. It is equally at home in drill presses, CNC machining centers, and hand-held power drills running at appropriate speeds for the workpiece material.

Key Features

• Wire size 10 diameter: 0.1935 inches — matches standard wire-gauge drill charts
• 135-degree split-point geometry reduces bit walk and lowers required feed pressure
• High-speed steel construction with straw bronze coating for improved wear resistance
• Web-thinned, tapered web design reduces thrust load and improves chip evacuation
• Regular spiral flute with right-hand cutting direction for standard drilling operations
• ANSI-specification compliant; heavy-duty grade rated for high-temp alloy applications

Compatibility

Part of the Series HX10-HX15-HX18 family. Designed as a general-purpose jobber-length drill bit compatible with any standard straight-shank drill chuck accepting a 0.1935-inch shank diameter. Rated for primary workpiece materials including high-temperature alloys and ISO material groups P, M, K, and S.

Installation Notes

Install into a properly sized drill chuck and tighten fully before operation. Secure the workpiece firmly before drilling to prevent movement. Select spindle speed appropriate to the workpiece material and drill diameter — high-temp alloys typically require lower surface footage than mild steel. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to maintain hole quality and prevent breakage.
