Guhring 9014520080000 Jobber Drill Bit 8 Mm Carbide

Product Description

The GUHRING 9014520080000 is a jobber-length solid carbide drill bit designed for precision hole-making in demanding shop and field applications. Built to DIN 6539 standards, it features a 150-degree drill point angle with a web-thinned, tapered web configuration for self-centering entry without a separate center punch. The submicron carbide grade delivers the edge retention needed for hard materials, while the bright uncoated finish keeps friction low in standard drilling operations. With three spiral flutes and a regular helix, chips clear efficiently from the cut zone during full-depth passes. Licensed machinists, tool-and-die workers, and industrial maintenance technicians are the primary users of this bit.

This drill bit is suited for precision drilling in metals including hardened steels, cast iron, and nonferrous alloys in both production and maintenance environments. It fits standard drill chucks and collet-style toolholders accepting a straight-cylindrical shank of 0.315 inches in diameter. The 5xD flute-to-diameter ratio supports drilling depths up to 36 mm (1.42 inches) before requiring a peck cycle. The Series 1452 design is appropriate for CNC machining centers, drill presses, and hand-held electric drills where carbide grades can be adequately supported without impact shock.

Key Features

• Submicron solid carbide construction for high edge retention in hard and abrasive materials
• 150-degree split point angle with web thinning for self-centering start and reduced thrust force
• Three-flute spiral design improves chip evacuation and surface finish compared to standard two-flute geometry
• Bright uncoated finish compatible with cutting fluids and coolant-assisted drilling setups
• Straight-cylindrical shank fits standard drill chucks and collet holders without modification
• Conforms to DIN 6539 specification for consistent dimensional tolerances across tool changes

Compatibility

Designed as an OEM-spec replacement or direct-use jobber drill for industrial toolholders and drill chucks accepting a straight-cylindrical shank at 8.00 mm (0.315 inches) diameter, conforming to DIN 6539 standards.

Installation Notes

This bit is installed by machinists or industrial maintenance technicians into a collet holder or keyed drill chuck rated for carbide tooling. Secure the shank fully within the chuck jaws or collet bore before operation, and verify runout with a dial indicator on CNC setups where tolerance is critical. Carbide is brittle under lateral or impact loading, so avoid using this bit in hammer-drill mode or in applications with interrupted cuts unless the setup is rigid. Always wear appropriate eye protection and follow applicable shop safety standards when operating rotary cutting tools.
