Guhring 9005010071400 Taper Length Drill Bit Hss

Product Description

The GUHRING 9005010071400 is a taper length twist drill bit designed for general-purpose drilling in metalworking and machining applications. Built from high speed steel (HSS) with a bright/uncoated finish, this Series 501 drill features a parabolic flute geometry and a web-thinned, parallel web configuration that improves chip evacuation and reduces feed force. The 130-degree split point provides accurate starts without center-punching on most materials. At 0.2810 inches (9/32 inch, Letter K) in diameter with a 6.125-inch overall length and a 4.031-inch flute length, it delivers an extended reach suited to deeper-than-standard holes compared to jobber-length tooling.

This drill is intended for right-hand cutting in aluminum alloy and steel. The parabolic flute profile and 10xD flute-to-diameter ratio make it effective in applications where chip packing is a concern, such as deep-hole passes without full retraction. The cylindrical shank seats directly in standard drill chucks and collet holders without adapters. Maximum drilling depth is rated at 3.594 inches (91.29 mm). Typical users include machinists, tool-and-die technicians, and maintenance mechanics working on manual or CNC drilling equipment.

Key Features

• Parabolic flute geometry promotes efficient chip removal in aluminum and steel
• Web-thinned parallel web reduces thrust force and improves point penetration
• 130-degree standard point angle for general-purpose metal drilling
• Taper length body extends reach beyond standard jobber drill proportions
• Bright/uncoated HSS construction suitable for use with cutting fluid or dry
• Conforms to DIN 340 specification for consistent dimensional tolerances

Compatibility

Designed as an OEM-style general-purpose taper length drill bit compatible with standard drill chucks and collet systems accepting a 9/32-inch cylindrical shank. Rated for use in aluminum alloy and steel per manufacturer material application data.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press, lathe, or CNC equipment operation. Secure the cylindrical shank fully in the chuck or collet before engaging the spindle. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before cutting. Inspect the drill point for wear or chipping before each use and replace when cutting performance degrades.
