Precision Twist Drill 6000151 Cobalt Drill Bit 1/16 in

Product Description

The PRECISION TWIST DRILL 6000151 is a cobalt high speed steel jobber length drill bit designed for demanding drilling applications in ferrous and non-ferrous materials. Built to NAS 907 standards, it features a 135-degree split point with web thinning for reduced walking and faster penetration on hard surfaces. The straight-cylindrical shank measures 1/16 inch (0.0625 inches) in diameter, and the overall length is 1-7/8 inches. The oxide and bronze finish provides surface hardness and heat resistance during high-speed operations. This bit is suited for use in drill presses, hand drills, and CNC drilling setups by machinists, maintenance technicians, and trade professionals.

This bit is rated for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. The regular spiral flute with a 7xD flute-to-diameter ratio provides efficient chip evacuation in both shallow and moderate-depth holes. With a maximum drilling depth of 7/16 inch and a two-flute spiral configuration, it is well suited for general-purpose production drilling in HVAC fabrication, plumbing rough-in metalwork, electrical panel work, and general mechanical trade applications.

Key Features

• Cobalt high speed steel construction for extended tool life in hard and abrasive materials
• 135-degree split point with web thinning reduces bit walking and entry force
• Oxide and bronze finish improves surface hardness and heat resistance
• Straight-cylindrical shank fits standard drill chucks without adapters
• NAS 907 standard compliance for consistent dimensional and performance requirements
• Right-hand cut with regular spiral flute for efficient chip removal

Compatibility

Designed as a general-purpose jobber length drill bit compatible with any standard drill chuck accepting a 1/16 inch straight-cylindrical shank. Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium per Series R88CO-R89CO specifications.

Installation Notes

Install in a drill press or hand drill with a chuck rated for 1/16 inch shanks, ensuring the bit is fully seated and the chuck key is removed before operation. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat buildup. Secure the workpiece firmly before drilling to prevent movement. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.
