Guhring 9005350015900 Taper Length Drill Bit 1/16 in Hss

Product Description

The GUHRING 9005350015900 is a taper length twist drill bit in the Series 535 line, designed for high-performance drilling in metalworking and industrial applications. Built from high speed steel (HSS) with a bright, uncoated finish, it features a parabolic flute geometry and web-thinned tip for efficient chip evacuation and reduced thrust. The 130-degree split point starts on contact without a center punch. At 3 inches overall length with a 1-31/32 inch flute, this bit handles deeper reach requirements that standard jobber-length drills cannot cover. It suits production drilling environments where tool life and hole quality matter.

This drill bit is rated for use in aluminum alloy, cast iron, and steel. The parabolic flute with a 10xD flute-to-diameter ratio moves chips out of the hole quickly, reducing heat buildup during extended cuts. The straight cylindrical shank fits standard drill chucks and collet holders. It is a practical choice for job shop machinists, maintenance technicians, and tool-and-die trades working with mixed ferrous and non-ferrous stock where a taper length reach is needed over a standard jobber drill.

Key Features

• 130-degree point angle for aggressive entry with reduced walking on hard materials
• Parabolic flute profile promotes fast chip evacuation in deep-hole applications
• Web-thinned tip lowers cutting thrust and extends tool life
• Taper length body provides extra reach beyond standard jobber length
• Bright, uncoated HSS construction suitable for regrinding and resharpening
• Conforms to DIN 340 specification for consistent dimensional standards

Compatibility

Rated for drilling aluminum alloy, cast iron, and steel. Fits any standard drill chuck or collet holder accepting a 1/16 inch straight cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with drilling operations and machine tool safety. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Always match spindle speed and feed rate to the workpiece material and bit diameter per standard machining practice. Inspect the cutting edges before each use and remove the bit from service if chipping or excessive wear is observed.
