Guhring 9014520126000 Carbide Jobber Drill Bit 12.6 Mm

Product Description

The GUHRING 9014520126000 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding machining applications. Built from submicron-grade carbide with a bright coating, it delivers consistent performance in ferrous and non-ferrous materials. The bit measures 12.6 mm in diameter (0.4961 inches) with an overall length of 102 mm (4.016 inches) and a flute length of 65 mm (2.559 inches). The 150-degree drill point angle and web-thinned, tapered web configuration reduce entry force and improve centering accuracy. This bit is intended for use in CNC machining centers, drill presses, and production environments where tight tolerances are required.

This jobber-length drill bit suits production machining in metalworking shops, tool rooms, and manufacturing facilities. Its straight-cylindrical shank accommodates standard drill chucks and collet holders across a wide range of machine spindles. The 3-flute spiral design promotes efficient chip evacuation, making it well-suited for through-hole and blind-hole drilling in materials that demand consistent finish and dimensional accuracy. It conforms to DIN 6539 specification, which governs solid carbide straight-shank twist drills for precision work.

Key Features

• Submicron solid carbide construction for hardness and wear resistance in high-production drilling
• 150-degree drill point angle reduces thrust force and improves self-centering on entry
• 3-flute spiral design with regular spiral type promotes fast, clean chip removal
• Web-thinned, tapered web lowers cutting resistance and extends tool life
• Bright (uncoated) finish maintains sharp edge geometry for clean bore surfaces
• Conforms to DIN 6539 specification for dimensional consistency and interchangeability

Compatibility

Designed as a DIN 6539-compliant jobber-length drill bit with a straight-cylindrical shank; fits standard drill chucks and collet holders sized for the 0.4961-inch shank diameter, suitable for machining operations within the 12.50 mm to 15.00 mm drill bit size range.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following standard tool-change procedures. Secure the shank fully within the chuck or collet to the manufacturer-recommended engagement depth before operating the spindle. Verify machine RPM and feed rate are appropriate for the workpiece material and bit diameter before drilling. Coolant-through is not supported on this bit; use external coolant or cutting fluid as required by the application.
