Guhring 9005150067500 Stub Drill Bit 17/64 in 130 Deg

Product Description

The GUHRING 9005150067500 is a stub-length (screw machine length) twist drill bit engineered for high-productivity drilling in ferrous workpiece materials. Built from powdered metal (PMASP60 grade) with a coated finish, this bit delivers extended tool life compared to standard HSS drills. It features a 17/64 inch (0.2656 inch) diameter, a 130-degree cone relief point, and a parabolic flute geometry that evacuates chips aggressively even in deeper cuts. The web-thinned, parallel-web configuration reduces entry thrust. Machinists, tool and die professionals, and maintenance technicians use this bit in drill presses, CNC machining centers, and hand-held power tools wherever compact stub-length tooling is required.

This drill bit is suited for production and maintenance drilling in cast iron and steel. The stub-length body keeps the tool rigid and minimizes deflection in short-reach drilling applications, making it a common choice for sheet metal fabrication, general machining, and repetitive hole-making operations. The straight-cylindrical shank fits standard drill chucks without adapters. The parabolic flute profile supports a maximum drilling depth of 0.94 inches (23.88 mm), making it appropriate for through-holes and blind holes within that depth range.

Key Features

• 17/64 inch (0.2656 inch) diameter with a diameter tolerance of +0.000 to -0.022 mm for precise hole sizing
• Powdered metal (PMASP60) construction with coated finish for improved wear resistance and heat management
• 130-degree cone relief point with web thinning reduces thrust load at entry
• Parabolic flute design (3xD flute-to-diameter ratio) promotes efficient chip evacuation
• Stub length body provides maximum rigidity and minimizes deflection during drilling
• Straight-cylindrical shank fits standard drill chucks with no special adapter required
• Conforms to DIN 1897 specification

Compatibility

Designed for drilling in cast iron and steel workpieces. Fits any standard drill chuck accepting a straight-cylindrical shank in the 17/64 inch diameter range.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified technicians familiar with drill press or CNC machine operation. Secure the shank fully in the chuck and verify runout before starting the cut. Always power down and lock out the machine before changing tooling. Do not exceed the maximum drilling depth of 0.94 inches without retracting to clear chips.
