Precision Twist Drill 5996413 Jobber Drill Bit 15/64 in

Product Description

The PRECISION TWIST DRILL 5996413 is a jobber-length drill bit designed for general-purpose drilling in metal and alloy materials. It measures 15/64 inches (0.2344 inches) in diameter with a 135-degree split-point angle, which reduces walking on entry and improves centering without a pilot hole. The bit is manufactured from M2 high-speed steel and features a bronze/purple coating for added surface hardness and heat resistance. Overall length is 3.875 inches with a 2.625-inch flute length. The straight cylindrical shank seats securely in standard drill chucks. This bit is installed by machinists, maintenance technicians, pipefitters, and general tradespeople working with metal fabrication or field drilling tasks.

This jobber-length drill bit is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium in both shop and field environments. The regular spiral flute geometry and web-thinned point make it effective on tough ferrous and exotic materials. It fits the HX10-HX15-HX18 series and is a single-piece per package unit intended for use in hand drills, drill presses, and CNC-compatible setups where a straight cylindrical shank is appropriate. Right-hand cut direction is standard for conventional drilling operations.

Key Features

• Bronze/purple coating adds surface hardness and reduces heat buildup during cutting
• Regular spiral, 2-flute design with tapered web configuration for efficient chip evacuation
• Compliant with ANSI standards; Series HX10-HX15-HX18

Compatibility

Designed for drilling steel, stainless steel, cast iron, superalloys, and titanium. Compatible with any drill chuck or holder accepting a 15/64 inch straight cylindrical shank. Part of the HX10-HX15-HX18 series.

Installation Notes

Install in a keyed or keyless drill chuck rated for the shank diameter and ensure the shank is fully seated and secured before operation. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat and extend tool life. Secure the workpiece firmly before drilling to prevent movement. Inspect the cutting edges for wear or chipping before each use and replace the bit if the tip shows signs of breakdown.
