Guhring 9005490016700 Jobber Drill Bit 1.67mm Hss

Product Description

The GUHRING 9005490016700 is a jobber length drill bit engineered for precision drilling in a range of materials. Built from high speed steel with a bright uncoated finish, this bit features a parabolic flute geometry and a web-thinned, tapered web configuration that promotes efficient chip evacuation and reduced thrust during drilling. The 130-degree point angle suits general-purpose applications with an emphasis on non-ferrous and soft materials. With an overall length of 43.00 mm (approximately 1-11/16 inches) and a flute length of 20.00 mm (25/32 inches), this bit fits standard drill chucks and is sized for detail work where tight tolerances matter. It is classified as a high performance grade under DIN 338.

This drill bit is rated for use with aluminum and similar non-ferrous and soft workpiece materials, as indicated by the primary workpiece material codes K, N, and P. Its 1.67 mm diameter and straight-cylindrical shank make it well suited for precision hole patterns on sheet metal, extrusions, and machined components. A parabolic flute profile, 5xD flute-to-diameter ratio, and right-hand cut orientation make this bit a reliable choice for machinists and trade professionals running production or maintenance drilling tasks.

Installation Notes

This bit is intended for installation by machinists or qualified trade professionals familiar with rotary cutting tool safety. Secure the shank fully in the chuck and verify runout before drilling. Always power down and de-energize the machine before changing bits. Follow applicable shop safety standards and manufacturer feed-and-speed guidelines for the workpiece material being drilled.
