Guhring 9005490050000 Jobber Drill 5mm Hss Din 338

Product Description

The GUHRING 9005490050000 is a 5.00 mm (0.1969 inch) diameter jobber-length twist drill designed for production and general-purpose drilling in metalworking applications. Built from high-speed steel (HSS) with a bright/uncoated finish, this Series 549 drill features a parabolic flute geometry that improves chip evacuation and reduces heat buildup during deep hole operations. The 130-degree point angle suits harder workpiece materials including steel and cast iron. Right-hand cutting, web-thinned tip, and tapered web construction reduce entry resistance and walking at the start of the cut. This drill is installed and used by machinists, tool-and-die workers, and maintenance professionals in both shop and field settings.

The 9005490050000 is suited for drilling steel, cast iron, aluminum, and non-ferrous materials in accordance with DIN 338 standards. The parabolic flute profile provides a 5xD flute-to-diameter ratio, allowing effective drilling to a maximum depth of 44.50 mm (1.752 inches) without step drilling in most applications. The straight cylindrical shank accepts standard drill chucks across a wide range of machine tools including drill presses, CNC machining centers, and hand-held power drills. This bit is a heavy-duty grade option appropriate for repetitive-cycle production environments as well as maintenance and repair operations.

Key Features

• 130-degree split point with web thinning reduces walking and entry force
• High-speed steel construction, bright/uncoated finish — suitable for HSS-compatible cutting fluids
• Tapered web configuration adds strength through the body of the drill
• Right-hand cut, 2-flute design; straight cylindrical shank fits standard drill chucks

Compatibility

Designed for use in standard drill chucks accepting 0.1969 inch (5.00 mm) straight cylindrical shanks. Compatible with steel, cast iron, aluminum, and non-ferrous workpiece materials per DIN 338 specification. Suitable for drill presses, CNC machining centers, and portable power drills.

Installation Notes

This drill bit is installed by machinists or qualified technicians using standard three-jaw or keyless drill chucks. Ensure the workpiece is securely fixtured and the spindle is fully stopped before changing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance. Do not exceed the recommended maximum drilling depth of 44.50 mm without retracting to clear chips.
