Guhring 9005350054100 Taper Length Drill Bit Hss

Product Description

The GUHRING 9005350054100 is a taper length twist drill bit built for professional metalworking applications where standard-length drills fall short. Part of the Series 535 line, this bit is manufactured from high-speed steel with a bright, uncoated finish and features a parabolic flute geometry designed to evacuate chips efficiently at depth. The 130-degree split point reduces walking and thrust force at entry. With a nominal wire gauge size of No. 3 and a decimal diameter of 0.2130 inches, this bit is sized for precision hole work in ferrous and non-ferrous metals. It is web-thinned with a parallel web configuration and conforms to DIN 340 specification, making it a high-performance tool suited for production environments.

This drill bit is intended for use in metalworking operations on aluminum alloy, cast iron, and steel. The taper length body provides additional reach compared to jobber-length bits, making it well suited for deeper through-hole drilling without requiring an extension. The parabolic flute and 10xD flute-to-diameter ratio support chip clearing in deeper cuts. It is appropriate for use in drill presses, CNC machining centers, and hand-held drill setups where a straight cylindrical shank is required. Machinists, toolroom technicians, and industrial maintenance professionals are the primary users of this tool.

Compatibility

Designed as a DIN 340 taper length drill bit for use in standard drill chucks and collets accepting a 0.2130-inch straight cylindrical shank across drill presses, machining centers, and hand-held drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with metal cutting operations. Secure the shank fully in a properly rated chuck or collet before operation and confirm the workpiece is firmly fixtured. Follow applicable shop safety procedures including appropriate RPM selection for the material and diameter. Do not exceed the maximum drilling depth of 3.2630 inches as specified for this bit geometry.
