Guhring 9014520047600 Carbide Jobber Drill Bit 3/16 in

Product Description

The GUHRING 9014520047600 is a solid carbide jobber-length drill bit designed for precision drilling in demanding materials. Built to DIN 6539 standards, this bit features a 150-degree drill point angle with web thinning for self-centering entry and reduced thrust. The three-flute spiral design improves chip evacuation and surface finish compared to standard two-flute geometry. At 3/16 inch (0.1875 inch) diameter with a bright uncoated finish, this bit is suited for ferrous and non-ferrous metals, composites, and hard plastics where dimensional accuracy and hole quality are critical. Licensed machinists, toolroom technicians, and production drilling operations are the primary users.

This drill bit fits applications requiring tight-tolerance holes in materials that demand carbide hardness and rigidity over high-speed steel. The straight-cylindrical shank accepts standard drill chucks and collet systems without modification. With a flute-to-diameter ratio of 5xD, it handles moderate drilling depths cleanly. Series 1452 positions this bit within a professional production line intended for CNC machining centers, drill presses, and hand-held precision drilling rigs operating in shop environments. It is not intended for hammer or rotary percussion applications.

Key Features

• Solid carbide submicron-grade construction for superior wear resistance in hard and abrasive materials
• 150-degree split point with web thinning provides self-centering entry and reduces walking on flat or curved surfaces
• Three-flute spiral geometry improves chip flow and extends tool life in short-run and production drilling
• Bright uncoated finish maintains dimensional consistency and suits applications where coating contamination is a concern
• DIN 6539 compliant with straight-cylindrical shank for direct chuck or collet mounting
• Maximum drilling depth of 1.097 inches (27.86 mm) within a compact 2-7/16 inch overall length

Compatibility

Designed as an OEM-style production drill bit conforming to DIN 6539 standards, suitable for use in standard drill chucks and collet systems accepting a 3/16 inch straight-cylindrical shank across CNC machining centers and manual drill presses.

Installation Notes

This bit should be installed by qualified machinists or toolroom personnel familiar with carbide tooling handling procedures. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout with an indicator when tight tolerances are required. Carbide is brittle — avoid side loading, interrupted cuts beyond the tool's rated capacity, or dropping the bit on hard surfaces. Always ensure the spindle is stopped and de-energized before changing tooling.
