Guhring 9005350040900 Taper Length Drill Bit Hss

Product Description

The GUHRING 9005350040900 is a taper length twist drill bit built for production drilling in metal fabrication and machining environments. This Series 535 drill is manufactured from high-speed steel (HSS) with a bright, uncoated finish and features a parabolic flute geometry for improved chip evacuation at deeper depths. The 130-degree split point reduces walking on entry and lowers thrust force. At 0.1610 inches in diameter (wire size No. 20), it delivers consistent hole quality in a wide range of ferrous and non-ferrous materials. The straight cylindrical shank seats securely in standard drill chucks and collets.

This drill bit is suited for through-hole and blind-hole work in aluminum alloy, cast iron, and steel. The taper length body with a 3-1/16-inch flute length and 4-11/16-inch overall length accommodates deeper reach applications compared to jobber-length bits of the same diameter. The 10xD flute-to-diameter ratio and web-thinned, parallel web construction support efficient chip flow in high-cycle production settings. It is typically used by machinists, tool-and-die makers, and maintenance professionals working on manual or CNC drill presses.

Compatibility

Rated for use in aluminum alloy, cast iron, and steel. Designed as a high-performance taper length replacement drill for applications requiring extended reach beyond standard jobber-length tooling in the No. 20 diameter class.

Installation Notes

A licensed machinist or qualified maintenance technician should install this bit in a drill press, mill, or CNC spindle using an appropriately sized chuck or collet. Ensure the machine is fully powered down and locked out before changing tooling. Inspect the shank and chuck jaws for wear or contamination before seating the bit. Follow applicable shop safety standards and manufacturer speed-and-feed recommendations for the specific work material.
