Guhring 9005020047600 Extra Length Drill Bit 3/16 in Hss

Product Description

The GUHRING 9005020047600 is an extra length high speed steel drill bit designed for deep hole drilling in a range of materials. Built to DIN 1869 standards, it features a parabolic flute geometry and a web-thinned, tapered web configuration that reduces cutting resistance and improves chip evacuation in extended-reach applications. The bit measures 0.1875 inches in diameter with a 5.315-inch flute length and a 7.677-inch overall length, providing a 15xD flute-to-diameter ratio suited to demanding depth requirements. Cutting direction is right hand, and the straight-cylindrical shank makes it compatible with standard drill chucks and collet holders.

This drill bit is intended for deep hole drilling operations in aluminum and similar non-ferrous and ferrous materials as indicated by its K, N, and P workpiece material designations. It is well-suited for machine shop, maintenance, and production environments where standard-length bits cannot reach required depths. The uncoated high speed steel construction is appropriate for operations where coolant-assisted cutting or re-sharpening is part of the standard workflow. Maximum drilling depth is 5.034 inches. This bit is typically used by machinists, tool-and-die professionals, and maintenance technicians working with drill presses, CNC machining centers, or handheld industrial drills.

Key Features

• Parabolic flute geometry promotes efficient chip removal during deep hole operations
• Web-thinned tapered web reduces thrust force at the cutting tip
• DIN 1869 specification ensures dimensional consistency and interchangeability
• Uncoated high speed steel construction supports re-sharpening and coolant use
• Straight-cylindrical shank fits standard chucks and collet systems without adapters
• Right-hand cutting direction for use with conventional drill configurations

Compatibility

Designed as an OEM-style replacement or direct-use extra length drill bit for applications requiring deep hole drilling in aluminum and similar materials per DIN 1869 specifications. Specific machine or equipment compatibility was not stated in the available product data.

Installation Notes

This bit is installed by machinists or maintenance technicians into a compatible drill chuck or collet holder. Ensure the drilling machine is fully powered down and secured before changing tooling. Verify that the shank diameter and chuck capacity match before tightening. Use appropriate cutting fluid or coolant as recommended for the workpiece material to maintain tool life and hole quality.
