Precision Twist Drill 6000733 Cobalt Jobber Drill 5.20mm

Product Description

The PRECISION TWIST DRILL 6000733 is a cobalt jobber-length drill bit designed for demanding metal drilling applications in shop and field environments. It features a 135-degree split point with web thinning for fast penetration and reduced walking on contact. The overall length is 3.3906 inches (86 mm), with a flute length of 2.0469 inches (52 mm). The drill is finished with a bronze oxide straw coating that provides lubricity and basic heat resistance during general-purpose drilling. Machinists, tool-and-die workers, and maintenance technicians use this bit for straight-hole work in steel and other primary workpiece materials.

This bit is intended for general-purpose drilling in steel, as well as compatible workpiece material categories including cast iron, non-ferrous metals, and heat-resistant alloys as indicated by the P, M, K, N, and S material codes. The straight cylindrical shank and right-hand spiral flute make it suitable for standard three-jaw chucks and drill presses. It conforms to DIN 338 and ANSI standards and belongs to the Series 2ACO heavy-duty grade lineup. The 10xD flute-to-diameter ratio supports chip evacuation in moderately deep holes.

Key Features

• Cobalt construction for improved heat resistance in steel drilling
• 135-degree split point with web thinning reduces thrust and prevents walking
• Bronze oxide straw finish adds lubricity and surface protection
• Tapered web configuration supports rigidity through the flute length
• Right-hand cut with regular spiral flute for standard chuck compatibility
• Meets DIN 338 and ANSI standards for consistent dimensional accuracy

Compatibility

Designed for use with standard straight-shank drill chucks on drill presses, CNC machining centers, and handheld power drills. Primary workpiece material codes P, M, K, N, and S indicate suitability for steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys per DIN material classification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Secure the shank fully in the chuck and verify concentricity before operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and manage heat. Do not exceed the rated maximum drilling depth of 2.0469 inches without retracting to clear chips.
