Guhring 9014520093000 Carbide Jobber Drill 9.3 Mm

Product Description

The GUHRING 9014520093000 is a solid carbide jobber-length drill bit designed for precision drilling in demanding production environments. Built to DIN 6539 standards, it features a 9.3 mm diameter, a 150-degree drill point angle, and a three-flute spiral design that promotes efficient chip evacuation and self-centering entry. The submicron carbide grade delivers the hardness and edge retention required when drilling hard metals, stainless steels, and other difficult-to-machine materials. The bright, uncoated finish maintains tight diameter tolerances from -0.015 to 0.000 mm. Machinists and toolroom professionals select this bit for CNC machining centers and precision drill press applications where concentricity and hole quality are critical.

This Series 1452 drill bit is suited for use in metalworking production shops, tool rooms, and manufacturing environments handling ferrous and non-ferrous alloys. Its self-centering point geometry reduces the need for center-drilling preparation, making it practical for high-volume hole operations. The straight-cylindrical shank fits standard drill chucks and collet holders, and the 5xD flute-to-diameter ratio supports controlled drilling depths up to 1.5 inches in a single pass without pecking cycles in many applications.

Key Features

• Solid carbide construction in submicron material grade for edge retention in hard materials
• 150-degree drill point angle with self-centering geometry reduces or eliminates center-drilling
• Three-flute spiral design promotes efficient chip evacuation and improved hole finish
• Web-thinned, tapered web configuration reduces thrust force at the cutting tip
• Bright uncoated finish with tight diameter tolerance of -0.015 to 0.000 mm
• Conforms to DIN 6539 standard for consistent interchangeability and dimensional accuracy

Compatibility

Designed as a DIN 6539 Series 1452 jobber-length drill bit with a straight-cylindrical shank, compatible with standard drill chucks and collet systems accepting a 0.3661-inch shank diameter in CNC machining centers, manual mills, and drill presses.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling practices. Secure the shank fully in the chuck or collet to the recommended grip depth before operation, and verify runout before beginning a production run. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without appropriate feed adjustments, or dropping the tool on hard surfaces. Always follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material.
