Guhring 9006510134900 Jobber Drill Bit 17/32 Inch Hss Tin

Product Description

The GUHRING 9006510134900 is a jobber length drill bit designed for general-purpose drilling in metalworking and fabrication applications. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS. The bit measures 17/32 inch (0.5313 inch decimal) in diameter with a 118-degree cone relief point angle and a web-thinned tip for reduced thrust and cleaner entry. Overall length is 160 mm with a flute length of 108 mm. The straight-cylindrical shank has a diameter of 13.49 mm (0.5311 inch decimal) and meets DIN 338 standards. Two spiral flutes with a regular helix and a 5xD flute-to-diameter ratio handle chip evacuation efficiently.

This bit is suited for drilling cast iron and steel in production, maintenance, and repair environments. The Series 651 designation places it within a general-purpose jobber-length family. Typical applications include drilling clearance holes, through holes, and pilot holes in ferrous metals. It cuts right hand and is compatible with standard drill presses, CNC machining centers, and hand-held power drills with appropriate chuck capacity for the 17/32 inch shank size. Maximum drilling depth is rated at 87.77 mm (3.456 inch decimal).

Compatibility

Designed as a general-purpose jobber length drill bit for use in ferrous metal applications including cast iron and steel, conforming to DIN 338 specification.

Installation Notes

Installation and use should be performed by a qualified machinist or tool operator familiar with metal cutting practices. Ensure the drill press or machine spindle is powered down and locked out before changing bits. Verify chuck capacity can accept the 17/32 inch shank diameter before mounting. Cutting speeds and feeds should be selected based on workpiece material and machine rigidity per standard machining references.
