Guhring 9005490018000 Jobber Drill Bit 1.8mm Hss Series 549

Product Description

The GUHRING 9005490018000 is a jobber length drill bit designed for precision drilling in a wide range of materials. Built from high speed steel (HSS) with a bright uncoated finish, this bit features a 1.8 mm diameter, a 130-degree drill point angle, and a parabolic flute geometry that promotes efficient chip evacuation. The overall length is 46.04 mm (1.8125 inches), with a flute length of 22 mm. Manufactured to DIN 338 standards, this bit is rated as high performance and carries a web-thinned, tapered web configuration for reduced thrust and cleaner entry. It is a single-piece unit with a straight-cylindrical shank.

This drill bit is suited for drilling aluminum and non-ferrous metals as well as a range of workpiece material codes including K, N, and P classifications. The parabolic flute design makes it well-suited for through-hole drilling where chip buildup is a concern. With a maximum drilling depth of 19.30 mm (0.760 inches) and a flute-to-diameter ratio of 5xD, it fits applications in light manufacturing, maintenance, and precision fabrication environments. It is typically used with bench-top drill presses, CNC machining centers, or handheld power tools where a straight-cylindrical shank is compatible. Series 549 identifies the Guhring product family this bit belongs to.

Key Features

• 1.8 mm diameter with a diameter tolerance of -0.014 to 0.000 mm for tight, repeatable hole sizing
• 130-degree point angle with web thinning reduces entry thrust and improves centering
• Parabolic flute geometry promotes fast chip evacuation, especially in aluminum
• High speed steel construction with bright uncoated finish — no coating to chip or delaminate
• Conforms to DIN 338 standard for interchangeability and consistent geometry
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style jobber length drill bit conforming to DIN 338, compatible with any drill press or machining spindle accepting a straight-cylindrical shank at 0.0709 inches (1.8 mm) shank diameter. Primary workpiece materials are aluminum and other non-ferrous metals in the K, N, and P material classification groups.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard drill chucks on manual or CNC equipment. Ensure the chuck is fully tightened and the shank is fully seated before operation. Verify spindle speed is appropriate for the workpiece material and bit diameter before engaging the cut. No coolant-through capability is present on this bit, so external cooling or cutting fluid should be applied when drilling harder or heat-sensitive materials.
