Precision Twist Drill 6000726 Jobber Drill 5mm Cobalt

Product Description

The PRECISION TWIST DRILL 6000726 is a cobalt high-speed steel jobber-length drill bit designed for drilling into steel and other demanding workpiece materials. It features a 135-degree split point with web thinning for fast engagement and reduced walking at the start of a hole. The bit measures 5.00 mm (0.1969 inches) in diameter with an overall length of 3.3906 inches (86.00 mm). A straw oxide finish helps with heat identification and provides light corrosion resistance during storage and use. With two regular spiral flutes and a straight cylindrical shank, this bit fits standard drill chucks and is suited for general-purpose production drilling in metal fabrication and maintenance environments.

This drill bit is intended for right-hand cutting in steel, cast iron, nonferrous metals, and specialty alloys, consistent with its P, M, K, N, and S workpiece material codes. It is well suited for use in drill presses, CNC machining centers, and hand-held power drills where a 5.00 mm hole diameter is required. The Series 2ACO designation indicates a heavy-duty cobalt grade built for elevated cutting temperatures. Licensed machinists, tool and die makers, millwrights, and general maintenance mechanics are the typical installers. This bit conforms to DIN 338 and ANSI standards.

Key Features

• Cobalt high-speed steel construction for improved heat and wear resistance in steel cutting
• 135-degree split point with web thinning reduces thrust and prevents bit walking
• Straw oxide finish provides light corrosion resistance and heat indication
• Regular spiral flute geometry promotes efficient chip evacuation
• Straight cylindrical shank fits standard three-jaw drill chucks without adapters
• Conforms to DIN 338 and ANSI standards for consistent dimensional accuracy

Compatibility

Designed as a general-purpose OEM-style replacement or stock drill bit for use in any standard drill chuck accepting a 5.00 mm straight shank; compatible with workpiece material codes P, M, K, N, and S as defined by the DIN 338 specification.

Installation Notes

Installation and use should be performed by a qualified machinist or trained maintenance mechanic familiar with metal cutting operations. Ensure the workpiece is securely clamped and the drill chuck is fully tightened before beginning any drilling operation. Power down and de-energize the machine completely before changing bits. Do not exceed the recommended maximum drilling depth of 2.0469 inches (52.00 mm) without retracting to clear chips.
