Guhring 9014520107200 Jobber Drill Bit 27/64 Carbide

Product Description

The GUHRING 9014520107200 is a solid carbide jobber length drill bit designed for precision drilling in demanding machining environments. Built to DIN 6539 specification, it features a 27/64 inch (0.4219 inch decimal) diameter with a 150-degree drill point angle and a three-flute spiral configuration. The bright coating finish leaves the carbide substrate exposed for high-performance cutting. The submicron carbide grade provides exceptional wear resistance and edge retention when drilling hard or abrasive materials. This bit is suited for machinists, tool-and-die shops, and maintenance professionals working with ferrous and non-ferrous metals on CNC and manual drilling equipment.

This jobber length drill bit is appropriate for production drilling applications where hole accuracy and tool life are critical. The web-thinned, tapered-web geometry reduces thrust force and improves chip evacuation. The straight cylindrical shank at 27/64 inch diameter provides secure retention in standard drill chucks and collet holders. The 3-3/4 inch overall length and 2-23/64 inch flute length make it compatible with typical jobber-length tool holders and setups in general metalworking, mold making, and precision fabrication.

Key Features

• Solid carbide submicron-grade construction for superior hardness and wear life
• 150-degree drill point angle reduces thrust and is suited for harder workpiece materials
• Three-flute spiral design improves chip evacuation over standard two-flute configurations
• Web-thinned tapered web lowers cutting resistance and entry force
• Bright coating finish with no thermal barrier for direct carbide-to-material contact
• Conforms to DIN 6539 specification for dimensional consistency

Compatibility

Designed as an OEM-specification jobber length drill bit for use in standard straight-shank drill chucks and collet systems accepting a 27/64 inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Secure the straight cylindrical shank fully in a properly sized chuck or collet before operation, and verify runout before drilling. Coolant through is not supported on this bit, so external coolant or cutting fluid application is recommended when drilling at elevated speeds or depths. Carbide tooling is brittle and should not be subjected to side loads or impacts during handling or machining.
