Guhring 9005350027800 Taper Length Drill Bit 7/64

Product Description

The GUHRING 9005350027800 is a taper length twist drill bit designed for precision hole-making in metal fabrication, machining, and industrial maintenance applications. Built to DIN 340 specification, this 7/64 inch (0.1094 inch) diameter bit is manufactured from high speed steel with a bright/uncoated finish. It features a parabolic flute geometry with a 10xD flute-to-diameter ratio, allowing for efficient chip evacuation in deeper drilling operations. The 130-degree split point reduces walking and improves entry accuracy. Overall length is 3-15/16 inches with a flute length of 2-19/32 inches, making it suitable for through-holes that standard jobber-length bits cannot reach.

This drill bit is suited for use on CNC machining centers, drill presses, and manual machine tools in both shop and field environments. It is rated for use in aluminum alloy, cast iron, and steel. The cylindrical shank fits standard drill chucks without adapters. The parabolic flute profile and web-thinned point make it particularly effective when drilling deeper holes where chip packing is a concern. It is sold individually and is a common choice for tool and die, general metalworking, and MRO applications.

Key Features

• DIN 340 taper length specification for deeper reach than standard jobber drills
• Parabolic flute with 10xD ratio for improved chip evacuation in deep-hole drilling
• 130-degree standard point angle with web-thinned tip for reduced thrust and accurate entry
• High speed steel construction rated for aluminum alloy, cast iron, and steel
• Bright/uncoated finish suitable for general-purpose machining
• Right-hand cut with cylindrical shank for universal chuck compatibility

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard drill chuck accepting a 7/64 inch cylindrical shank, including CNC machining centers, drill presses, and hand drills. Rated for aluminum alloy, cast iron, and steel workpiece materials per Series 535 specifications.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Always wear appropriate eye protection and follow shop safety procedures when operating drilling equipment. Inspect the cutting edge for wear or damage before each use and replace if chipping or dulling is observed.
