Guhring 9005010111100 Taper Length Drill Bit 7/16 in

Product Description

The GUHRING 9005010111100 is a taper length twist drill bit engineered for general-purpose hole-making in metalworking and fabrication applications. Built from high speed steel (HSS) with a bright, uncoated finish, this bit features a parabolic flute design and a web-thinned, parallel web configuration that reduces thrust and improves chip evacuation. The 130-degree point angle suits a broad range of materials, including aluminum alloy and steel. With a 7/16 inch diameter and an overall length of 7-11/16 inches, this bit delivers extended reach in situations where a standard-length drill falls short. It is sized to the DIN 340 specification and carries a 10xD flute-to-diameter ratio, giving it a maximum drilling depth of 4.383 inches.

This drill bit is suited for machine shop environments, production drilling, and maintenance operations where taper length reach is required. Its right-hand cut and cylindrical shank make it compatible with standard drill chucks and CNC machining centers. Rated for general-purpose performance, it handles both aluminum alloy and steel workpieces, making it a practical choice for job shops, tool rooms, and industrial maintenance technicians working across mixed-material applications.

Key Features

• Parabolic flute geometry promotes efficient chip removal and reduces heat buildup during drilling
• Web-thinned parallel web lowers cutting thrust and extends tool life in production use
• 130-degree standard point angle provides broad material compatibility including aluminum alloy and steel
• Taper length body (overall 7-11/16 inches) extends reach beyond standard jobber-length drills
• DIN 340 specification ensures dimensional consistency for interchangeability in tooling setups
• Bright, uncoated HSS construction allows easy resharpening and visual wear inspection

Compatibility

Designed for use in aluminum alloy and steel applications per Series 501 DIN 340 specification. The cylindrical, non-threaded 7/16 inch shank fits standard drill chucks used in drill presses, lathes, and CNC machining centers.

Installation Notes

This bit is installed by machinists and tool-and-die technicians using standard drill chuck equipment. Secure the shank fully in the chuck and verify concentricity before operating at speed. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for steel applications to manage heat and extend tool life.
