Guhring 9005350017000 Taper Length Drill Bit 0.067 in Hss

Product Description

The GUHRING 9005350017000 is a taper length twist drill bit designed for precision hole-making in metalworking and machining applications. Built to DIN 340 specification, this Series 535 bit measures 0.0670 inches in diameter with a 3-inch overall length and a parabolic flute geometry that promotes efficient chip evacuation. The 130-degree split point reduces walking at entry and allows drilling without a center punch on many workpieces. Manufactured from high speed steel with a bright/uncoated finish, it is suited for use in CNC machines, drill presses, and manual setups where consistent performance at small diameters is required.

This bit is rated for use in aluminum alloy, cast iron, and steel. The parabolic flute with web-thinned, parallel web construction supports deeper drilling with reduced thrust compared to standard geometry bits. The flute-to-diameter ratio of 10xD and a maximum drilling depth of 1.868 inches make it appropriate for through-holes and moderate-depth blind holes in production and job-shop environments. The cylindrical shank diameter of 0.0669 inches fits standard collet chucks and drill chucks sized for wire gauge tooling.

Key Features

• DIN 340 taper length specification for extended reach in small-diameter drilling
• Parabolic flute geometry promotes chip flow and reduces clogging in deep holes
• 130-degree standard point angle reduces drill walk and entry burr
• Web-thinned parallel web lowers thrust requirements at the cutting edge
• High speed steel construction handles aluminum alloy, cast iron, and steel
• Bright/uncoated finish allows easy wear inspection during service

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill for applications requiring wire gauge size 51 (0.0670 inches) tooling in standard cylindrical-shank collet chucks and drill chucks.

Installation Notes

Installation is performed by machinists and tool-and-die professionals using standard drill chucks or collet holders rated for the 0.0669-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm chuck or collet runout is within acceptable tolerance for small-diameter bits, as excessive runout accelerates wear and increases breakage risk at this diameter. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drilling equipment.
