Guhring 9005350017800 Taper Length Drill Bit Wire 50

Product Description

The GUHRING 9005350017800 is a taper length twist drill bit in the Series 535 line, manufactured from high-speed steel (HSS) with a bright/uncoated finish. It carries a wire gauge designation of No. 50, corresponding to a decimal diameter of 0.0700 inches and a shank diameter of 0.0701 inches. The 130-degree split point and parabolic flute geometry combine to reduce walking on entry and improve chip evacuation in deeper holes. A web-thinned parallel web further lowers thrust requirements during drilling. This bit is suited for precision drilling applications where hole accuracy and clean entry are priorities, and is typically installed and operated by machinists, maintenance technicians, and tool-and-die professionals.

This drill bit is designed for use in aluminum alloy, cast iron, and steel. The parabolic flute profile and 10xD flute-to-diameter ratio make it well matched to taper-length drilling operations where standard jobber bits fall short in reach. The right-hand cut configuration is compatible with conventional drill presses, CNC machining centers, and handheld power tools with right-hand spindle rotation. It conforms to DIN 340 specification, which defines the taper length standard for this class of drill.

Key Features

• Wire size No. 50 — 0.0700 inch decimal diameter for precision hole sizing
• 130-degree point angle reduces walking and improves on-location entry
• Parabolic flute design promotes efficient chip evacuation in deeper cuts
• Web-thinned parallel web lowers axial thrust during drilling
• Bright/uncoated HSS construction — suitable for regrinding and general shop use
• Conforms to DIN 340 taper length specification

Compatibility

Rated for use in aluminum alloy, cast iron, and steel workpiece materials. Straight cylindrical shank is compatible with standard drill chucks and collet holders accepting a 0.0701-inch shank diameter.

Installation Notes

Secure the shank fully in the chuck or collet before operation and verify runout before beginning a cut. Always power down the machine and lock out the spindle before changing bits. Use appropriate cutting fluid or coolant for the workpiece material when drilling steel or cast iron to extend tool life. Dispose of worn or cracked bits in accordance with shop safety protocols — do not attempt to use a visibly damaged cutting tool.
