Guhring 9005350039100 Taper Length Drill Bit Hss

Product Description

The GUHRING 9005350039100 is a taper length twist drill bit in the Series 535, designed for production drilling in metal fabrication and machining environments. It carries a wire gauge size of 23, equal to 0.1540 inches in diameter, and features a 130-degree split point with web thinning for reduced thrust and cleaner entry. The parabolic flute geometry promotes efficient chip evacuation at extended depths, supporting a flute-to-diameter ratio of 10xD. Built from high-speed steel with a bright, uncoated finish, this drill suits applications where coating is not required or where regrinding frequency is high.

This drill bit is rated for use in aluminum alloy, cast iron, and steel. The taper length body provides added reach compared to a jobber-length drill, making it suitable for through-hole work in thicker stock or where clearance is needed beyond the spindle face. It is commonly used in manual drill presses, CNC machining centers, and gang-drilling fixtures in light manufacturing and job shop environments. The straight cylindrical shank fits standard drill chucks without adapters.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or tool-and-die technician. Secure the shank fully in the chuck and verify concentricity before running at speed. Follow machine manufacturer guidelines for feed rate and spindle speed based on workpiece material. Inspect the cutting edges for wear or chipping before each use, and regrind or replace when point geometry is compromised to avoid workpiece damage or drill breakage.
