Guhring 9005490054100 Jobber Drill No 3 Hss 130 Deg

Product Description

The GUHRING 9005490054100 is a No. 3 wire-size jobber-length drill bit built to DIN 338 standards from high-speed steel (HSS) with a bright, uncoated finish. It features a 130-degree split point with web thinning and a tapered web configuration for improved chip evacuation and reduced walking on entry. The parabolic flute geometry provides a flute-to-diameter ratio of 5xD, supporting deeper hole depths while maintaining efficient chip clearance. At 3.6563 inches overall length with a 2.25-inch flute, this is a heavy-duty tool suited for drilling steel, cast iron, aluminum, and other non-ferrous materials. A licensed GUHRING distributor part, this bit is intended for professional machining and maintenance environments.

This drill bit is designed for use in drill presses, CNC machining centers, and hand drills where a straight cylindrical shank is required. The No. 3 wire-size diameter of 0.2130 inches fits applications in metalworking shops, maintenance-repair-operations, and production drilling across ferrous and non-ferrous workpieces. The right-hand cut and parabolic flute suit moderate-to-deep hole drilling in steel and cast iron where chip control is critical. It is sold individually as a single unit.

Key Features

• No. 3 wire size, 0.2130 inch decimal diameter with a tolerance of -0.018 to 0.000 mm
• 130-degree split point with web thinning reduces thrust and self-centers on entry
• Parabolic flute geometry at 5xD ratio for efficient chip evacuation in deeper holes
• Tapered web configuration adds rigidity and extends tool life in heavy-duty applications
• Bright, uncoated HSS construction — compatible with cutting fluids and re-sharpenable
• Conforms to DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement and production drilling tool for any application requiring a straight-shank jobber drill in No. 3 wire size (0.2130 inch). Primary workpiece materials listed by the manufacturer include steel, cast iron, aluminum, and non-ferrous metals (material codes P, K, N).

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with rotating-tool safety. Secure the straight cylindrical shank in a properly sized chuck and verify concentricity before drilling. Power down and fully de-energize any machine before changing or inspecting the bit. Do not exceed the maximum recommended drilling depth of 1.925 inches without retracting to clear chips, and use appropriate cutting fluid for ferrous workpieces to extend tool life.
