Guhring 9005350045000 Taper Length Drill Bit Hss

Product Description

The GUHRING 9005350045000 is a taper length twist drill bit built to DIN 340 standards in high-speed steel (HSS) with a bright, uncoated finish. It cuts a 0.1770-inch diameter hole, equivalent to a Number 16 wire gauge size, and features a 130-degree split point for accurate self-starting penetration with reduced walking. The parabolic flute geometry accelerates chip evacuation and reduces heat buildup during extended drilling cycles. With a flute-to-diameter ratio of 10xD and a web-thinned design, this bit handles deeper holes than standard jobber-length drills. Licensed tradespeople and machinists rely on this drill for production and maintenance drilling in light to medium materials.

This drill bit is suited for drilling aluminum alloy, cast iron, and steel in both shop and field environments. The cylindrical straight shank, with a diameter of 0.1772 inches, seats directly into standard drill chucks and quick-change holders without adapters. At a flute length of 3-7/32 inches and an overall length (OAL) of 4-31/32 inches, it reaches into recessed bores and confined cavities where shorter jobber-length bits cannot. Typical applications include hole-making for fasteners, conduit anchor points, pipe fittings, and light structural work in fabrication or mechanical service settings.

Key Features

• DIN 340 taper length specification for deeper reach than standard jobber drills
• 130-degree point angle with web thinning for self-centering entry and reduced thrust
• Parabolic flute with 10xD flute-to-diameter ratio for efficient chip removal in deep holes
• High-speed steel construction with bright/uncoated finish suitable for aluminum alloy, cast iron, and steel
• Right-hand cut with parallel web configuration for consistent geometry throughout the flute length
• Straight cylindrical shank compatible with standard drill chucks and holders

Compatibility

Designed for use in standard drill chucks and quick-change tooling systems that accept a straight cylindrical shank at 0.1772-inch diameter. Suitable for drilling aluminum alloy, cast iron, and steel as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the shank fully in the drill chuck and verify runout before cutting. Always power down and de-energize the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 2.963 inches per the manufacturer specification, and use appropriate cutting fluid for the workpiece material to extend tool life.
