Guhring 9005010063500 Taper Length Drill Bit 1/4 in Hss

Product Description

The GUHRING 9005010063500 is a taper length twist drill bit designed for general-purpose drilling in metalworking and fabrication applications. Built from high speed steel (HSS) with a bright/uncoated finish, this bit measures 0.2500 inches in diameter with an overall length of 5-13/16 inches and a parabolic flute geometry that promotes efficient chip evacuation. The 130-degree split point reduces walking on entry and works well across a range of workpiece materials. A web-thinned, parallel web configuration reduces thrust requirements during drilling. This bit is part of the Guhring Series 501 line and is sold individually as a single-piece unit.

This drill bit is suited for right-hand drilling operations in aluminum alloy and steel workpieces in shop, production, and field environments. The cylindrical shank measures 0.2500 inches in diameter, making it compatible with standard chucks and collet holders used in drill presses, CNC machining centers, and hand-held drilling equipment. The parabolic flute design and 10xD flute-to-diameter ratio support deeper hole applications with a maximum drilling depth of 3.444 inches. It conforms to DIN 340 specification, a standard common in precision machining and toolroom environments. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this type of tooling.

Key Features

• High speed steel construction for general-purpose metalworking durability
• Parabolic flute geometry promotes efficient chip removal in deeper holes
• 130-degree standard point angle reduces drill walk on entry
• Web-thinned parallel web lowers axial thrust requirements
• Bright/uncoated finish suitable for use with cutting fluids or dry drilling
• Conforms to DIN 340 specification for taper length drills

Compatibility

Rated for drilling in aluminum alloy and steel. Cylindrical shank fits standard 1/4-inch drill chucks and collet systems. Conforms to DIN 340 taper length drill standards.

Installation Notes

This tooling is installed by machinists and maintenance technicians in drill presses, lathes, or CNC spindles with an appropriate chuck or collet sized for a 0.2500-inch shank. Ensure the workpiece is securely fixtured and the spindle is at a complete stop before changing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear or chipping before each use.
