Guhring 9005490105000 Jobber Drill 10.50mm Hss Series 549

Product Description

The GUHRING 9005490105000 is a heavy-duty jobber-length twist drill built to DIN 338 standards from high-speed steel (HSS) with a bright, uncoated finish. It carries a 10.50 mm (0.4134 inch) diameter, a 130-degree split point for reduced walking and faster penetration, and a parabolic flute geometry that evacuates chips efficiently during deeper passes. Right-hand cutting direction, a straight cylindrical shank, and web-thinned tip geometry make it a reliable production drill for machine shop, maintenance, and fabrication use. Overall length is 133.00 mm (approximately 5.234 inches).

This drill is suited for through-hole and blind-hole drilling in steel, cast iron, aluminum, and other non-ferrous materials. The parabolic flute design and web-thinned point are particularly effective in CNC machining centers, drill presses, and hand-operated column drills where consistent chip flow and hole quality are required. With a 5xD flute-to-diameter ratio and a maximum recommended drilling depth of 71.25 mm (approximately 2.805 inches), it handles a broad range of production and maintenance drilling tasks without pilot drilling in most standard applications.

Key Features

• 10.50 mm diameter, DIN 338 jobber-length standard
• 130-degree standard point with web thinning reduces thrust and prevents walking
• Parabolic flute geometry improves chip evacuation in deeper holes
• High-speed steel construction rated for steel, cast iron, aluminum, and non-ferrous workpieces
• Bright, uncoated finish suitable for use with cutting fluids or dry
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed for use in standard drill chucks accepting straight-shank tooling in the 10.50 mm diameter range, conforming to DIN 338 jobber-length specifications for use in CNC machining centers, drill presses, and hand drills.

Installation Notes

This drill is installed and serviced by machinists, tool-and-die technicians, and maintenance mechanics. Secure the shank fully in a calibrated drill chuck before operation and verify runout before production use. Always follow machine-specific speed and feed recommendations for the workpiece material. Inspect the cutting edges and web for wear before each use and replace the drill if chipping or dullness is observed to prevent workpiece damage or tool breakage.
