Guhring 9005350015500 Taper Length Drill Bit 0.0610 in

Product Description

The GUHRING 9005350015500 is a taper length twist drill bit designed for precision drilling in metalworking and fabrication applications. Built from high speed steel (HSS) with a bright/uncoated finish, this bit features a 130-degree drill point angle and a parabolic flute geometry that promotes efficient chip evacuation and reduced thrust during drilling operations. The cylindrical shank measures 0.0610 inches in diameter, matching the drill diameter. With an overall length of 76.00 mm (approximately 2.99 inches) and a flute length of 1.9688 inches, this bit provides additional reach compared to jobber-length equivalents. It is installed by machinists, tool-and-die professionals, and maintenance technicians working with drill presses, CNC machines, or hand drills.

This drill bit is suited for use in aluminum alloy, cast iron, and steel. The taper length format — longer than a standard jobber bit — makes it practical for applications requiring extended reach or deeper hole starting without stepping up to a longer series bit. The web-thinned tip reduces walking on entry and improves centering on the workpiece. It is a single-piece, individually packaged bit conforming to DIN 340 specification.

Key Features

• 0.0610-inch (1.55 mm) drill diameter with a tight tolerance of +0.000 to -0.014 mm
• Parabolic flute design for improved chip evacuation in aluminum, cast iron, and steel
• 130-degree standard point angle suited for general metalworking entry
• Web-thinned tip with parallel web configuration for reduced thrust and improved centering
• Taper length body (flute-to-diameter ratio of 10xD) provides additional reach over jobber-length bits
• Conforms to DIN 340 specification; right-hand cut with cylindrical shank

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard drill chucks and collet systems accepting a 0.0610-inch cylindrical shank. Compatible with materials including aluminum alloy, cast iron, and steel per Series 535 design intent.

Installation Notes

This bit is installed by machinists and metalworking technicians using a drill press, lathe, or CNC machine with an appropriate collet or chuck. Ensure the machine is powered down and the spindle is stopped completely before changing tooling. Secure the cylindrical shank firmly in the chuck or collet to the full gripping depth to prevent slippage at small diameters. At 0.0610 inches diameter, use appropriate low feed rates and cutting speeds per the material being drilled to avoid bit breakage.
