Guhring 9014520045000 Jobber Drill Bit 0.1772 in Carbide

Product Description

The GUHRING 9014520045000 is a solid carbide, jobber length drill bit designed for precision drilling in demanding shop and production environments. Built to DIN 6539 standards, this bit measures 0.1772 inches in diameter with an overall length of 2.2835 inches and a 150-degree drill point angle. The three-flute spiral geometry combined with a web-thinned, tapered web design allows for self-centering entry without a pilot hole. The bright, uncoated finish is suited for applications where coating buildup or heat retention is a concern. Machinists, tool-and-die technicians, and CNC operators working with precision hole tolerances will find this bit appropriate for production-grade drilling applications.

This bit is intended for use in standard drill chucks or CNC machining centers accepting a straight-cylindrical shank. The 5xD flute-to-diameter ratio and 1.2598-inch flute length support chip evacuation in moderate-depth holes up to a maximum drilling depth of 0.9940 inches. The submicron carbide grade provides the hardness and edge retention needed when drilling ferrous and non-ferrous materials where consistent hole quality and dimensional accuracy are required across high-cycle runs.

Key Features

• Solid carbide submicron grade construction for extended tool life in high-cycle drilling
• Three-flute spiral design improves chip evacuation compared to standard two-flute geometry
• 150-degree drill point angle with web thinning enables self-centering entry
• Straight-cylindrical shank at 0.1772 inches diameter fits standard drill chucks and collets
• Meets DIN 6539 specification for consistent dimensional and tolerance compliance
• Bright, uncoated finish suitable where coated tooling is not preferred or required

Compatibility

Designed as a DIN 6539 jobber length drill bit in the GUHRING Series 1452, compatible with any standard drill chuck or collet system accepting a 0.1772-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with proper tooling setup procedures. Ensure the machine spindle is fully stopped and the tool holder is secured before inserting or removing the bit. Verify chuck or collet runout is within acceptable limits before production use, as excess runout will accelerate carbide tool wear. Do not exceed the maximum drilling depth of 0.9940 inches without retracting to clear chips.
