Guhring 9014520071400 Carbide Drill Bit Letter K 9/32

Product Description

The GUHRING 9014520071400 is a solid carbide jobber length drill bit sized at letter K (9/32 inch, 0.2812 inch decimal), designed for precision drilling in hard and abrasive materials. Built to DIN 6539 standards, it features a 150-degree point angle with a standard point geometry and web-thinned, tapered web construction that promotes self-centering entry and reduces thrust. The bright uncoated finish preserves dimensional accuracy on the cutting edge. With a regular spiral flute and three-flute configuration, this bit delivers efficient chip evacuation in demanding applications. Qualified machinists and tool-and-die professionals install this bit in CNC machining centers and manual drill presses where tight hole-location tolerances are required.

This drill bit is suited for use in metalworking environments where solid carbide tooling is specified over high-speed steel, particularly when drilling hardened steels, cast iron, and other wear-intensive materials. The Series 1452 design follows a 5xD flute-to-diameter ratio, offering a 1.7656-inch flute length within a compact 2-29/32-inch overall length. The straight-cylindrical shank seats directly in standard chucks and collet holders without adapter modifications. It is commonly used in production drilling, toolroom work, and precision fabrication where repeatability and hole quality are critical.

Key Features

• Solid carbide submicron-grade material for hardness and wear resistance in abrasive workpieces
• 150-degree point angle with web-thinned, tapered web for self-centering performance and reduced entry thrust
• Three-flute spiral design promotes faster chip evacuation compared to standard two-flute geometry
• Bright uncoated finish maintains precise cutting-edge geometry for tight tolerance drilling
• Straight-cylindrical shank fits standard chucks and collet holders without modification
• Manufactured to DIN 6539 specification for consistent dimensional quality

Compatibility

Designed as a DIN 6539 Series 1452 jobber length drill bit with a straight-cylindrical shank; compatible with any standard drill chuck or collet holder sized for a 9/32-inch shank diameter in CNC machining centers, manual drill presses, and similar equipment.

Installation Notes

This bit is installed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank fully in a compatible collet or chuck before operation, and verify runout with a dial indicator when precision hole location is required. Carbide tooling is brittle and should never be used in applications with excessive vibration or interrupted cuts unless the setup is rigid and properly supported. Always follow machine manufacturer guidelines and applicable shop safety protocols when changing or running carbide drill bits.
