Precision Twist Drill 5996407 Jobber Drill Bit 13/64 in

Product Description

The PRECISION TWIST DRILL 5996407 is a 13/64 inch (0.2031 inch) diameter high speed steel jobber drill bit with a bronze coating and a 135-degree split point. It is designed for general-purpose drilling in steel, stainless steel, cast iron, superalloys, and titanium. The web-thinned, tapered web construction reduces thrust force at the cutting tip, improving penetration efficiency. With a regular spiral and two straight-cylindrical shank flutes, this bit is a reliable choice for production drilling environments. Licensed HVAC, plumbing, mechanical, and sheet metal tradespeople will find it suited to everyday hole-making tasks in metal fabrication and equipment service work.

This drill bit is part of the HX10-HX15-HX18 series and is intended for right-hand rotation in standard drill chucks and drill presses. Its 3-5/8 inch overall length and 2-7/16 inch flute length make it appropriate for jobber-length drilling applications in ferrous and high-alloy workpiece materials. The straight-cylindrical shank accepts standard three-jaw drill chucks without modification, making it compatible with common handheld and bench-mounted drilling equipment used in trade and light industrial settings.

Key Features

• 135-degree split point reduces walking and improves self-centering on hard surfaces
• Bronze coating provides lubricity and helps reduce heat buildup during drilling
• Web-thinned tapered web lowers thrust requirements for cleaner entry
• High speed steel construction withstands elevated cutting temperatures in ferrous materials
• Right-hand spiral flute with regular helix for chip evacuation in steel, stainless steel, cast iron, superalloys, and titanium
• ANSI-standard geometry for consistent sizing and fitment in standard drill chucks

Compatibility

Designed for use in steel, stainless steel, cast iron, superalloys, and titanium workpieces. Part of the PRECISION TWIST DRILL HX10-HX15-HX18 series. Fits any standard drill chuck accepting a 13/64 inch straight-cylindrical shank.

Installation Notes

This drill bit is installed by machinists, sheet metal workers, and trade professionals using standard drill chucks on handheld drills or drill presses. Secure the straight-cylindrical shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant for ferrous and high-alloy materials to extend tool life, noting this bit does not include a coolant-through channel. Inspect the cutting edges before use and replace the bit if chipping or excessive wear is present.
