Precision Twist Drill 5997112 11/64 Inch Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5997112 is a high-speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in steel, aluminum, and non-ferrous materials. It measures 11/64 inch (0.1719 inch) in diameter with a 135-degree split point for fast engagement and reduced walking on entry. The overall length is 3.25 inches with a 2.125-inch flute length, and the straight cylindrical shank matches the drill diameter at 0.1719 inch. A web-thinned, tapered web design reduces thrust and improves chip evacuation. This bit is suited for use by machinists, HVAC technicians, plumbers, electricians, and general trade professionals who need a reliable general-purpose bit for light to medium drilling tasks.

This drill bit is built for use on ferrous and non-ferrous workpieces including steel, aluminum, and similar materials. The QC21P series is designed as a standard jobber-length bit for bench drill presses, handheld drills, and drill motors commonly used in trade and light manufacturing environments. The bright uncoated finish makes it straightforward to inspect for wear. It is appropriate for any application where a standard ANSI-compliant jobber drill is called for in general shop or field work.

Key Features

• 135-degree split point reduces bit walking and improves positioning on entry
• Web-thinned tapered web lowers drilling thrust and improves chip clearance
• High-speed steel construction provides durability across steel and non-ferrous materials
• Bright uncoated finish allows easy visual inspection of cutting edge condition
• Right-hand cut with regular spiral flute geometry for standard drilling operations
• Conforms to ANSI standards for jobber-length drill bits

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks and quick-change systems that accept straight cylindrical shanks at 11/64 inch diameter. Suitable for use in drill presses, cordless drills, and electric drill motors used across HVAC, plumbing, electrical, and general fabrication trades.

Installation Notes

Secure the shank fully in the chuck before operation and verify the bit is centered and running true before engaging the workpiece. Use appropriate cutting fluid or lubricant when drilling steel to extend cutting edge life and reduce heat buildup. Always wear eye protection and secure the workpiece to prevent movement during drilling. Disconnect power to any drill press before changing bits or making chuck adjustments.
