Guhring 9005350025300 Taper Length Drill Bit 39 Hss

Product Description

The GUHRING 9005350025300 is a taper length drill bit in the Series 535 line, designed for high-performance drilling in metalworking applications. Built from high speed steel (HSS) with a bright/uncoated finish, it features a parabolic flute geometry and a web-thinned tip for reduced thrust and improved chip evacuation. The 130-degree point angle suits general-purpose work across a range of materials. At wire size 39 (0.0995 inch decimal), this bit delivers close-tolerance performance with a diameter tolerance of +0.000 to -0.014 mm. Licensed machinists and tool-and-die technicians are the primary installers of this type of tooling.

This drill bit is suited for production and maintenance drilling in aluminum alloy, cast iron, and steel. The parabolic flute profile with a 10xD flute-length-to-diameter ratio supports deeper cuts with better chip clearance than standard jobber-length bits. The taper length body provides added rigidity over jobber style in short-setup machining environments. It conforms to DIN 340 specification, making it a recognized standard for taper length drills in precision shops and industrial maintenance settings.

Key Features

• Wire size 39 (0.0995 inch) with tight diameter tolerance of +0.000 to -0.014 mm
• 130-degree standard point angle with web-thinned tip for reduced entry force
• Parabolic flute design promotes efficient chip evacuation at deeper depths
• High speed steel construction with bright/uncoated finish
• Right-hand cut with straight cylindrical shank for standard drill chuck mounting
• Conforms to DIN 340 taper length specification

Compatibility

Designed as a DIN 340-compliant taper length drill bit compatible with standard drill chucks and collet systems that accept a 0.0996-inch cylindrical shank. Suitable for use in aluminum alloy, cast iron, and steel workpieces.

Installation Notes

This tooling is installed and operated by machinists, tool-and-die technicians, and industrial maintenance professionals using standard drill presses, CNC machining centers, or hand-held power tools with compatible chucks. Always ensure the workpiece is properly fixtured and the spindle is at a full stop before changing tooling. Inspect the cutting edges for wear or chipping before each use. Follow applicable ANSI and shop safety standards for rotating cutting tool operation.
