Precision Twist Drill 6000567 Cobalt Jobber Drill 8.80mm

Product Description

The PRECISION TWIST DRILL 6000567 is a cobalt jobber-length drill bit designed for drilling operations in steel and other demanding workpiece materials. Built to DIN 338 and ANSI standards, it features a 135-degree split point geometry with web thinning for reduced walking and lower thrust on entry. The bit measures 8.80 mm (0.3465 inches) in diameter with an overall length of 4-59/64 inches (125 mm) and a flute length of 3-3/16 inches (81 mm). The oxide and bronze straw coating provides lubricity and heat resistance during high-speed drilling cycles. This is a heavy-duty grade tool suited for professional metalworking environments.

The 6000567 is intended for general-purpose drilling in steel, cast iron, non-ferrous metals, and high-temp alloys, consistent with its P, M, K, N, and S workpiece material classifications. The straight cylindrical shank fits standard drill chucks without adapters, making it compatible with floor-standing drill presses, mag-base drills, and hand-held power drills used in fabrication, maintenance, and machine shop applications. It runs right-hand cutting with a regular spiral flute for efficient chip evacuation.

Key Features

• Cobalt high-speed steel construction for elevated heat and wear resistance in ferrous materials
• 135-degree split point with web thinning reduces thrust and eliminates center punch requirement on most surfaces
• Oxide and bronze straw coating adds lubricity and extends tool life in high-cycle applications
• Regular spiral flute promotes consistent chip evacuation and reduces recutting
• Tapered web configuration maintains rigidity along the full flute length
• Meets DIN 338 and ANSI dimensional standards for interchangeability

Compatibility

Designed as a general-purpose jobber drill for use in any standard drill chuck accepting a 8.80 mm (0.3465 inch) straight shank, including drill presses, magnetic base drills, and CNC drilling fixtures rated for that shank diameter.

Installation Notes

Installation and operation of this drill bit should be performed by machinists, millwrights, or qualified tradespeople familiar with rotary cutting tools. Ensure the drill press or power tool is powered off and isolated before inserting or removing the bit from the chuck. Verify chuck jaws are fully tightened and shank seating is secure before beginning any drilling operation. Always use appropriate cutting fluid for the workpiece material to maximize tool life and maintain surface finish.
