Precision Twist Drill 5996802 Jobber Drill Bit 5/8 in

Product Description

The PRECISION TWIST DRILL 5996802 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. Built from high-speed steel (HSS) with a bright uncoated finish, it features a 135-degree split-point tip that reduces walking on entry and lowers thrust requirements compared to a standard 118-degree point. The parabolic spiral flute geometry improves chip evacuation and helps maintain cutting efficiency in deeper holes. At 5/8 inch (0.6250 inch) diameter with a 7.125-inch overall length, this bit covers a wide range of production and maintenance drilling tasks across fabrication, HVAC, plumbing, and electrical trade applications.

This drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight-cylindrical shank accepts standard drill chucks on both benchtop drill presses and handheld power drills. The QC21P series targets heavy-duty general-purpose use, making it appropriate for trade professionals who drill through structural steel, pipe hangers, enclosures, and similar workpieces encountered in daily service and installation work.

Key Features

• 135-degree split-point tip reduces bit walking and lowers drilling thrust
• Parabolic spiral flute promotes efficient chip clearing in deep holes
• High-speed steel construction handles steel, cast iron, non-ferrous metals, superalloys, and titanium
• Web-thinned, tapered web design extends cutting performance under heavy-duty conditions
• Straight-cylindrical shank fits standard 3-jaw drill chucks without an adapter
• ANSI-compliant jobber-length geometry for consistent sizing across tooling setups

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 5/8-inch straight-cylindrical shank, including benchtop drill presses, magnetic drills, and handheld power drills used in metalworking and trade installation work.

Installation Notes

This bit is installed and operated by machinists, fabricators, and trade professionals including HVAC technicians, plumbers, and electricians performing metal drilling tasks. Always secure the workpiece firmly before drilling and use appropriate cutting fluid or coolant when drilling stainless steel, cast iron, or superalloys to extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed. Follow applicable ANSI safety standards for drilling operations including eye protection and secure workpiece fixturing.
