Guhring 9005010011800 Taper Length Drill Bit 0.0465 in

Product Description

The GUHRING 9005010011800 is a taper length twist drill bit designed for precision hole-making in metalworking and machining applications. Built from high speed steel (HSS) with a bright/uncoated finish, this bit features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced cutting force. The cylindrical shank measures 0.0465 inches in diameter, matching the cutting diameter, and the overall length is 2.375 inches. Web-thinned construction improves penetration at the start of the cut. This bit is suited for machinists, tool-and-die technicians, and production drilling operations requiring consistent, repeatable results in small-diameter work.

This drill bit is rated for general-purpose drilling in aluminum alloy and steel. The taper length body, at 1.469 inches of flute length, provides greater reach than a jobber-length bit without sacrificing rigidity, making it appropriate for drilling operations where standard-length bits fall short. It conforms to DIN 340 specifications, which defines taper length drill geometry and tolerances. Typical applications include CNC machining centers, drill presses, and manual drilling fixtures where wire-gauge sizing is specified. The bit carries a Wire Gauge size of No. 56.

Key Features

• 130-degree point angle for reduced thrust force and cleaner entry on steel and aluminum
• Parabolic flute profile enhances chip flow and reduces packing in deep-hole drilling up to 10xD depth
• Web-thinned tip reduces cutting resistance and improves centering
• High speed steel construction provides toughness across general-purpose applications
• Bright/uncoated finish — suitable for use with cutting fluids without coating compatibility concerns
• Conforms to DIN 340 taper length standard for dimensional consistency

Compatibility

Designed as a DIN 340 taper length replacement or direct-use drill bit for applications requiring a No. 56 wire gauge diameter (0.0465 inches) in aluminum alloy and steel. Compatible with standard drill press chucks and CNC spindle tool holders accepting cylindrical shank tooling at this diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with small-diameter drill bit handling. Secure the cylindrical shank firmly in a precision drill chuck or collet to minimize runout, which is critical at sub-0.05-inch diameters. Always bring the spindle to a full stop before changing or inspecting the bit. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-diameter tolerance.
