Guhring 9005350027100 Taper Length Drill Bit 36 Hss

Product Description

The GUHRING 9005350027100 is a taper length drill bit from the Series 535 line, designed for precision drilling in demanding trade and industrial applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 130-degree standard point angle and a parabolic flute geometry with web thinning for improved chip evacuation and reduced thrust. The drill cuts at a wire gauge size of 36, corresponding to a decimal diameter of 0.1065 inches, with a cylindrical shank diameter of 0.1067 inches. At 3-15/16 inches overall length and a 2-19/32 inch flute length, this bit offers extended reach compared to jobber-length equivalents. It is intended for machinists, tool-and-die technicians, and precision fabricators.

This drill bit is suited for right-hand cut drilling in aluminum alloy, cast iron, and steel. The taper length design makes it well matched to applications requiring deeper hole penetration than standard jobber bits allow. With a maximum drilling depth of 2.439 inches and a flute-to-diameter ratio of 10xD, it handles through-hole and deep-drilling operations on manual mills, drill presses, and CNC machining centers. The parabolic flute profile supports efficient chip clearing in both ferrous and non-ferrous materials across production and maintenance environments.

Key Features

• Wire gauge size 36 (0.1065 inch decimal diameter) with tight diameter tolerance of +0.000 to -0.014 mm
• 130-degree standard point angle with web-thinned, parallel web construction for reduced entry force
• Parabolic flute geometry promotes fast chip removal in aluminum, cast iron, and steel
• High-speed steel construction with bright, uncoated finish suitable for a broad range of work materials
• Taper length body at 3-15/16 inches OAL provides extended reach over jobber-length equivalents
• Conforms to DIN 340 specification; rated as a high-performance drill bit grade

Compatibility

Designed for use in materials including aluminum alloy, cast iron, and steel. Compatible with standard drill chucks and collets accepting a 0.1067-inch cylindrical shank. Suitable for use on manual drill presses, milling machines, and CNC equipment consistent with DIN 340 taper length tooling requirements.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die technicians familiar with small-diameter HSS tooling. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before changing tooling. Use appropriate cutting fluid for ferrous materials to extend tool life and maintain hole quality. Do not exceed the recommended drilling depth of 2.439 inches for this bit geometry.
