Precision Twist Drill 5996254 23/64 in Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5996254 is a high-speed steel jobber-length drill bit ground to a 135-degree split point with a bronze (straw) coating. It is designed for general-purpose drilling in metals including high-temperature alloys, cast iron, and steel. The bit runs at a nominal diameter of 23/64 inches (0.3594 inches decimal) with a web-thinned tip that reduces thrust and improves hole entry. Machining professionals, tool-and-die shops, and maintenance mechanics reach for this style of bit when working with demanding workpiece materials where point geometry and tool grade matter. The M2 high-speed steel substrate handles heat and edge wear well in production environments.

This bit fits standard jobber-drill applications in machining, fabrication, and maintenance settings. It is suited for use in drill presses, CNC drilling operations, and hand-held electric drills where a straight-shank bit is required. The HX10-HX15-HX18 series designation indicates a flute-to-diameter ratio of 10xD, making it a match for through-hole and moderate-depth drilling work in materials coded P, M, K, and S — covering steel, stainless, cast iron, and high-temp alloys. No coolant-through capability is built in, so external coolant or cutting fluid should be applied at the workpiece when drilling harder materials.

Key Features

• 135-degree split point with web thinning reduces thrust and self-centers on entry
• M2 high-speed steel construction rated for heavy-duty, general-purpose drilling
• Bronze (straw) coating provides lubricity and mild heat resistance
• Regular spiral flute with tapered web for efficient chip evacuation
• Straight cylindrical shank at 23/64 inches fits standard drill chucks without adapters
• ANSI-standard geometry ensures dimensional consistency and interchangeability

Compatibility

Designed for use in standard drill chucks accepting a straight shank of 0.3594 inches diameter. Part of the PRECISION TWIST DRILL HX10-HX15-HX18 series. Suitable for drilling high-temp alloys, steel, stainless steel, and cast iron per material codes P, M, K, and S.

Installation Notes

A licensed machinist or qualified maintenance technician should verify chuck capacity and runout before seating the bit. Secure the shank fully in the chuck and confirm the bit is centered before starting the spindle. Apply cutting fluid or coolant to the workpiece when drilling stainless steel or high-temperature alloys to extend tool life. Do not exceed the recommended drilling depth of 3.5 inches, and clear chips frequently on deep-hole passes to prevent flute packing.
