Guhring 9005350035700 Taper Length Drill Bit 0.1405in Hss

Product Description

The GUHRING 9005350035700 is a taper length twist drill bit designed for precision hole-making in metalworking applications. Built to DIN 340 specification, this Series 535 bit is machined from high-speed steel (HSS) with a bright, uncoated finish and features a parabolic flute geometry that promotes efficient chip evacuation at greater drilling depths. The 130-degree split point reduces walking on entry and lowers thrust force. With a wire gauge size of 28 (0.1405 inches decimal), a flute length of 2-7/8 inches, and an overall length of 4-13/32 inches, it is sized for work that exceeds the reach of jobber-length tooling. A web-thinned parallel web design reduces cutting resistance across supported materials.

This drill bit is suited for production and maintenance machining environments where taper length reach is required. The parabolic flute profile with a 10xD flute-to-diameter ratio makes it effective in aluminum alloy, cast iron, and steel. The straight cylindrical shank with a 9/64-inch diameter fits standard drill chucks without an adapter. Right-hand cutting direction is standard. It is used by machinists, tool-and-die technicians, and maintenance mechanics working on CNC machines, drill presses, and handheld drilling equipment.

Key Features

• DIN 340 taper length specification for deeper reach than standard jobber-length bits
• Parabolic flute geometry with 10xD ratio for improved chip flow in deep holes
• 130-degree point angle with web thinning reduces entry force and bit walking
• High-speed steel construction, bright uncoated finish, suitable for aluminum alloy, cast iron, and steel
• Straight cylindrical shank fits standard drill chucks directly
• Maximum drilling depth of 2.663 inches (67.65 mm)

Compatibility

Designed for use in standard drill chucks accepting a straight cylindrical shank. Suitable for aluminum alloy, cast iron, and steel workpieces as stated in manufacturer material application data.

Installation Notes

This bit is installed and removed by a qualified machinist or maintenance technician using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify runout before cutting. Always wear appropriate eye protection and ensure the workpiece is firmly clamped. When drilling cast iron or steel, use appropriate cutting fluid and feed rates consistent with HSS tooling recommendations to prevent premature edge wear.
