Guhring 9005490015000 Jobber Drill Bit 1.5mm Hss

Product Description

The GUHRING 9005490015000 is a jobber-length drill bit engineered for high-performance drilling in light-metal and non-ferrous applications. Built from high speed steel (HSS) with a bright, uncoated finish, it features a 130-degree point angle and a parabolic flute geometry that improves chip evacuation and reduces heat buildup at depth. The bit measures 1.5 mm in diameter with an overall length of 40.00 mm (approximately 1-37/64 inches) and a usable flute length of 18.00 mm. Web thinning at the tip reduces entry force and improves centering on soft and gummy materials. This bit is manufactured to DIN 338 standards and is well suited for machinists, tool-and-die tradespeople, and maintenance technicians who require consistent tolerance drilling in production or field environments.

This drill bit is optimized for primary workpiece materials classified as aluminum, non-ferrous metals, and plastics (material codes K, N, and P per ISO designation). Its parabolic flute profile and 5xD flute-to-diameter ratio make it effective in shorter through-hole and blind-hole operations where chip clearing is a priority. The straight-cylindrical shank seats directly in standard drill chucks and collet systems without adapters. Series 549 identifies this as a Guhring high-performance jobber-length line conforming to DIN 338 geometry.

Key Features

• 1.5 mm diameter with a diameter tolerance of -0.014 to 0.000 mm for precise, repeatable hole sizing
• 130-degree split point angle reduces walking and lowers thrust force on entry
• Parabolic flute geometry accelerates chip removal in deep or interrupted cuts
• Web-thinned, tapered web configuration minimizes cutting resistance at the tip
• Bright, uncoated HSS finish — suitable for aluminum, plastics, and soft non-ferrous metals
• Conforms to DIN 338 standard geometry for interchangeability with DIN-spec toolholding

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 0.0591-inch (1.5 mm) straight-cylindrical shank. Suited for CNC machining centers, benchtop drill presses, and hand drills operating within the DIN 338 jobber-length tooling envelope.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tool safety. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Do not exceed the recommended maximum drilling depth of 15.75 mm (0.620 inches) per pass without retracting to clear chips. Cutting fluid or light lubrication is recommended when drilling aluminum or plastics to extend tool life and maintain hole quality.
