Precision Twist Drill 6000737 5.30mm Cobalt Jobber Drill

Product Description

The PRECISION TWIST DRILL 6000737 is a cobalt jobber-length drill bit designed for general-purpose drilling in steel and other ferrous and non-ferrous materials. It features a 135-degree split point with web thinning for fast engagement and reduced walking on entry. The oxide and straw coating provides lubricity and heat resistance during high-speed drilling operations. At 5.30 mm (0.2087 inches) in diameter with a straight cylindrical shank, this bit seats securely in standard keyed and keyless chucks. The regular spiral flute geometry evacuates chips efficiently across the full 2.047-inch flute length. Built to DIN 338 and ANSI standards, it is suited for machinists, maintenance technicians, and fabricators working in production or job-site environments.

The 6000737 is appropriate for drilling steel, cast iron, aluminum, and similar workpiece materials as defined by material codes P, M, K, N, and S. The 10xD flute-to-diameter ratio makes it a standard jobber-length option for through-hole and blind-hole drilling in both handheld and machine-mounted drill applications. Its heavy-duty grade construction supports repeated use in production settings without rapid edge breakdown.

Key Features

• Cobalt construction for elevated heat resistance compared to standard HSS bits
• 135-degree split point with web thinning reduces thrust and minimizes walking
• Oxide and straw coating adds lubricity and corrosion resistance
• Regular spiral flute with tapered web for consistent chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• Meets DIN 338 and ANSI specifications for dimensional consistency

Compatibility

Designed as an OEM-style jobber drill bit for use in standard 3-jaw keyed or keyless drill chucks accepting straight-shank bits up to 0.2087 inches in shank diameter. Suitable for benchtop drill presses, CNC drilling machines, and handheld power drills.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with proper chuck-seating and feed-rate selection. Secure the shank fully in the chuck jaws before applying power, and verify chuck key is removed before starting the spindle. Use appropriate cutting fluid or lubricant when drilling steel to extend tool life and maintain cut quality. Follow applicable ANSI B11 machine tool safety standards when operating drill presses or CNC equipment.
