Guhring 9005350034500 Taper Length Drill Bit 29 Hss

Product Description

The GUHRING 9005350034500 is a taper length drill bit in the Series 535 line, ground from high-speed steel (HSS) with a bright, uncoated finish. It is sized to wire gauge number 29, which equals 0.1360 inches in decimal. The 130-degree split point and parabolic flute design work together to reduce walking at entry and clear chips efficiently during deeper drilling operations. A web-thinned, parallel web construction reduces thrust requirements and helps maintain accuracy through the cut. This bit is suited to production and job-shop environments where taper length reach and precise hole sizing are required in metal fabrication and mechanical assembly work.

This drill bit is designed for right-hand cutting in materials including aluminum alloy, cast iron, and steel. The taper length format provides extended reach beyond a jobber-length bit, making it useful in applications where standard-length drills cannot access the workpoint. With a flute-to-diameter ratio of 10xD and a maximum drilling depth of 2.67 inches, it handles through-holes and deeper blind holes in structural components, fixtures, and machined parts. It is typically used by machinists, tool-and-die tradespeople, and maintenance mechanics running drill presses or CNC equipment.

Key Features

• Wire size number 29 (0.1360 inches decimal) for precise hole sizing
• 130-degree point angle with web thinning reduces entry thrust and walking
• Parabolic flute profile promotes fast chip evacuation in deep-hole drilling
• High-speed steel construction handles aluminum alloy, cast iron, and steel
• Taper length body with 10xD flute-to-diameter ratio for extended reach applications
• Straight cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 340 specification for consistent dimensional tolerances

Compatibility

Designed as an OEM-style taper length drill bit replacement for applications requiring wire gauge number 29 sizing in standard drill chucks accepting a 0.1358-inch cylindrical shank. Compatible with materials stated in the product data: aluminum alloy, cast iron, and steel.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press, hand drill, or CNC spindle operation. Secure the workpiece firmly before drilling and verify chuck grip on the cylindrical shank before applying feed pressure. Always wear appropriate eye protection and follow shop safety protocols when drilling metal. Do not exceed the rated maximum drilling depth of 2.67 inches per pass without retracting to clear chips.
