Guhring 9005490027800 Jobber Drill 7/64 Inch Hss

Product Description

The GUHRING 9005490027800 is a high-speed steel jobber-length drill bit designed for production and maintenance drilling in steel, cast iron, aluminum, and other non-ferrous materials. Built to DIN 338 standards, this heavy-duty bit features a 130-degree split point and a parabolic flute geometry that promotes faster chip evacuation and reduces the tendency to walk on entry. The web-thinned, tapered-web construction lowers thrust requirements, making it well suited for hand-held and machine drilling applications. The bright uncoated finish keeps the tool ready to use straight out of the package without additional prep.

This Series 549 drill is intended for general-purpose metalworking in both shop and field environments. The 7/64 inch diameter and 2-13/32 inch overall length place it in the standard jobber range, appropriate for tap-drill sizing, clearance holes, and light fabrication work. The straight cylindrical shank seats directly in standard drill chucks without adapters. Machinists, maintenance technicians, pipefitters, and HVAC fabricators routinely keep this size on hand for everyday ferrous and non-ferrous drilling tasks. The right-hand cutting direction is compatible with all standard drill presses, CNC machining centers, and portable drills.

Key Features

• Parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup
• 130-degree point angle with web thinning lowers entry thrust and reduces walking
• Heavy-duty HSS construction rated for steel, cast iron, aluminum, and non-ferrous workpieces
• DIN 338 specification ensures dimensional consistency and interchangeability
• Straight cylindrical shank fits standard 3-jaw and keyless drill chucks without adapters
• Bright uncoated finish — no break-in required; compatible with cutting fluids

Compatibility

Designed as a DIN 338-compliant jobber drill for use in standard drill chucks accommodating a 7/64 inch straight shank. Suitable for drilling steel, cast iron, aluminum, and non-ferrous materials as specified by the manufacturer for Series 549.

Installation Notes

Install in a standard 3-jaw or keyless drill chuck and tighten securely before operation. Use appropriate cutting fluid or coolant when drilling ferrous materials to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear before each use; a dull point increases thrust and can cause workpiece damage. Follow applicable shop safety practices and machine guarding requirements during all drilling operations.
