Precision Twist Drill 5997052 6mm Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5997052 is a high speed steel (HSS) jobber-length drill bit in the QC21PM series, designed for general-purpose drilling in production and maintenance environments. Ground to a 135-degree split point with web thinning, it starts on contact without a center punch and reduces thrust compared to standard 118-degree geometry. The straight cylindrical shank measures 6.00 mm (0.2362 inches) in diameter. Overall length is 93.00 mm (3.656 inches), with a flute length of 57.00 mm (2.25 inches). The bright, uncoated finish suits general shop use and allows for easy visual wear inspection. Licensed machinists, maintenance technicians, and trade professionals install this bit in standard drill presses, hand drills, and CNC drilling operations.

This bit is rated for drilling steel, aluminum, and non-ferrous metals, corresponding to material codes P, M, K, N, and S under DIN 338 classification. It is suited to residential and commercial maintenance shops, fabrication environments, and field service where a reliable general-purpose drill bit is required. The QC21PM series follows DIN 338 standards, making it a recognized specification in industrial supply. The regular spiral flute geometry handles chip evacuation in the typical materials this bit encounters, and the right-hand cutting direction is compatible with standard drill chucks and drivers.

Key Features

Compatibility

Designed for use in standard straight-shank drill chucks on drill presses, hand drills, and CNC drilling machines. Rated for steel, aluminum, and non-ferrous workpiece materials per DIN 338 material codes P, M, K, N, and S.

Installation Notes

Install in a properly sized drill chuck and tighten with a chuck key before operation. Ensure the workpiece is securely clamped before drilling. Apply appropriate cutting fluid when drilling steel to extend bit life and manage heat. Inspect the cutting edges and web thinning for wear or chipping before each use and replace if the point shows signs of heat discoloration or edge breakdown.
