Guhring 9006090125000 Carbide Jobber Drill Bit 12.5mm

Product Description

The GUHRING 9006090125000 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding machining applications. Built to DIN 6539 specification, it features a titanium nitride (TiN) coating over a submicron carbide substrate, which increases surface hardness and extends tool life in abrasive materials. The 150-degree point angle and web-thinned, tapered web configuration reduce thrust force at entry and improve chip evacuation. With three spiral flutes and a straight-cylindrical shank, this bit is suited for use in CNC machining centers, drill presses, and rigid toolholding setups where consistent, repeatable hole quality is required.

This drill bit is intended for metalworking and precision machining environments, including production shops, tool rooms, and maintenance facilities. The 12.5 mm diameter and jobber-length geometry make it appropriate for general-purpose drilling in steel, cast iron, aluminum alloys, and similar materials where carbide tooling is specified. It is typically installed and operated by machinists and CNC programmers working within established feeds-and-speeds parameters for carbide tooling. The DIN 6539 standard designation makes it a direct fit for applications that call out that specification.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance
• Titanium nitride (TiN) coating increases hardness and reduces friction at the cutting edge
• 150-degree point angle reduces entry thrust and improves centering accuracy
• Three-flute spiral design improves chip evacuation compared to standard two-flute geometry
• Web-thinned tapered web lowers cutting resistance and extends tool life
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a DIN 6539-compliant jobber-length drill bit for use in drill presses, machining centers, and other rigid setups that accept a 12.5 mm straight-cylindrical shank. No specific model or system compatibility was provided in the product data.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Secure the shank fully in a collet, drill chuck, or toolholder rated for the shank diameter before operation. Carbide tooling is brittle and can fracture if subjected to lateral shock or side loads — avoid hand-held or unsupported setups. Follow established speeds-and-feeds guidelines for solid carbide drills in the material being machined, and inspect the cutting edge for chipping before each use.
