Guhring 9014520063500 Carbide Jobber Drill Bit Letter E

Product Description

The GUHRING 9014520063500 is a solid carbide jobber-length drill bit sized at Letter E (0.2500 inches / 1/4 inch) with a 150-degree drill point angle. Built to DIN 6539 standards, this bit features a 3-flute spiral configuration with a web-thinned, tapered web for improved chip evacuation and self-centering entry. The submicron carbide grade delivers the hardness and heat resistance needed for consistent performance in demanding production drilling applications. The bright, uncoated finish is suitable for a range of workpiece materials. Overall length is 2.75 inches with a straight-cylindrical shank of 0.2500 inches diameter.

This Series 1452 drill bit is suited for precision jobber-length drilling in machine shop, manufacturing, and maintenance environments. Its self-centering point geometry reduces the need for a center punch or pilot hole on flat and prepared surfaces. The right-hand cut with regular spiral flute geometry handles a broad range of materials. Maximum drilling depth is 1.279 inches, making it appropriate for through-holes and shallow blind holes in production setups where accuracy and repeatability matter.

Key Features

• Solid carbide construction in submicron grade for extended tool life in hard or abrasive materials
• 150-degree point angle with self-centering geometry reduces walking and pilot hole requirements
• 3-flute spiral design improves chip removal and supports higher feed rates compared to standard 2-flute bits
• Web-thinned tapered web lowers thrust force at entry
• Bright uncoated finish compatible with a wide range of cutting fluids and dry applications
• Manufactured to DIN 6539 specification for consistent dimensional accuracy

Compatibility

Designed as a direct-fit jobber-length carbide drill bit for use in CNC machining centers, drill presses, and hand-held drilling equipment accepting a 1/4-inch straight-cylindrical shank. Fits any machine spindle or chuck rated for 0.2500-inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter to prevent runout. Solid carbide tooling is brittle and should not be used in setups with excessive vibration or side-loading, as this can cause fracture.
