Guhring 9006530060000 Stub Drill Bit 6mm Hss Series 653

Product Description

The GUHRING 9006530060000 is a screw machine length (stub) drill bit designed for high-production drilling applications in ferrous and cast materials. Manufactured from M2 high speed steel with a coated finish, this bit measures 6.00 mm (0.2362 inches) in diameter with an overall length of 66.00 mm (2.5984 inches). The 118-degree cone relief point, web-thinned geometry, and 2-flute regular spiral design allow for accurate starts and efficient chip evacuation. Built to DIN 1897 standards, this is a heavy-duty grade tool suited for machinists, tool and die tradespeople, and metalworking professionals requiring consistent, repeatable hole quality.

This stub-length drill bit is intended for use in CNC machining centers, drill presses, and hand-held drilling equipment where a shorter flute length improves rigidity and reduces deflection. Primary workpiece materials include cast iron and steel. The straight-cylindrical shank with a diameter of 0.2362 inches (6.00 mm) fits standard collets and chucks without adapters. The maximum drilling depth is 0.7480 inches (19.00 mm), making this bit well suited for shallow-hole, high-accuracy operations typical in production machine shops and maintenance environments.

Key Features

• Manufactured from M2 high speed steel with a coated finish for extended tool life in ferrous materials
• 118-degree cone relief point with web-thinned geometry for accurate centering and reduced thrust
• DIN 1897 stub-length design improves rigidity and minimizes deflection in deep-reach setups
• 2-flute regular spiral flute profile supports efficient chip evacuation
• Straight-cylindrical shank (h8 tolerance) fits standard collets and drill chucks
• Heavy-duty grade construction rated for cast iron and steel workpieces

Compatibility

Designed as an OEM-style replacement or standard tooling option for drilling applications in cast iron and steel. Compatible with any drill press, CNC machining center, or power tool accepting a 6.00 mm straight-cylindrical shank within the 0.2000 to 0.2500 inch drill bit size range.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the chuck or collet is clean and free of debris before seating the shank. Verify runout with a dial indicator when precision hole tolerances are required. Follow shop safety protocols and applicable OSHA machining guidelines when operating drilling equipment.
