Precision Twist Drill 6000753 Cobalt Jobber Drill 6.20mm

Product Description

The PRECISION TWIST DRILL 6000753 is a cobalt high-speed steel jobber-length drill bit designed for drilling operations in steel and other demanding workpiece materials. It measures 6.20 mm (0.2441 inches) in diameter with an overall length of 3-31/32 inches (3.9688 inches). The 135-degree split point reduces walking at entry and lowers thrust requirements compared to a conventional 118-degree point. A straw oxide finish provides mild lubricity and surface protection. The web-thinned, tapered web design improves chip evacuation and cutting efficiency. This bit is suited for licensed machinists, maintenance technicians, pipefitters, and HVAC or plumbing professionals who drill steel components in the field or shop.

The 6000753 is built for general-purpose drilling in steel, cast iron, non-ferrous metals, and non-metallic materials, consistent with its P, M, K, N, and S workpiece material codes. With a flute length of 2-31/64 inches (2.4844 inches) and a maximum drilling depth of 2.4803 inches, it handles standard through-hole and blind-hole applications in light to heavy plate. The straight cylindrical shank fits standard drill chucks without adapters. It conforms to DIN 338 and ANSI standards, making it a reliable replacement or service-stock bit for trade shop inventories.

Key Features

• Cobalt construction for heat resistance and durability in steel drilling
• 135-degree web-thinned split point reduces entry walking and cutting thrust
• Straw oxide finish provides surface lubricity and corrosion resistance
• Regular spiral flute geometry promotes consistent chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• Meets DIN 338 and ANSI dimensional standards for consistent fitment

Compatibility

Designed for general-purpose use across steel, cast iron, non-ferrous metals, and composite materials (workpiece codes P, M, K, N, S). Straight shank fits any standard keyed or keyless drill chuck accepting a 6.20 mm (0.2441 inch) shank diameter.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using standard drill presses, hand drills, or magnetic-base drills. Secure the straight shank fully in the chuck before operation and verify chuck key is removed before starting. Use appropriate cutting fluid or coolant when drilling steel to extend tool life; this bit does not support coolant-through delivery. Dispose of worn bits per applicable shop safety protocols and replace before cutting edge degradation causes oversized holes or workpiece damage.
