Guhring 9055110087000 Carbide Jobber Drill Bit 8.7mm

Product Description

The GUHRING 9055110087000 is a solid carbide jobber length drill bit engineered for high-performance drilling in demanding materials. Built to DIN 6537L specification, it features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance for extended tool life in production environments. With an overall length of 103 mm (4.055 inches) and a spiral flute design, this bit is suited for machinists, toolmakers, and fabricators working on precision drilling applications in a shop or manufacturing setting.

This drill bit is designed for right-hand cutting in cast iron and steel workpieces. The 2-flute regular spiral configuration with a tapered web supports efficient chip evacuation during deep-hole passes. Coolant-through capability allows internal delivery of cutting fluid directly to the cutting zone, making it appropriate for CNC machining centers and high-cycle drilling operations where heat management is critical. The 5xD flute-to-diameter ratio provides adequate flute length for moderate-depth applications.

Key Features

• Solid carbide submicron-grade construction for rigidity and edge retention
• FIREX coating for enhanced heat and wear resistance
• 140-degree SU split point with web thinning for self-centering entry
• Coolant-through design for internal cutting fluid delivery
• Right-hand, 2-flute regular spiral for efficient chip removal
• Meets DIN 6535 and DIN 6537 L standards

Compatibility

Designed for drilling cast iron and steel workpieces in CNC machining centers and conventional drill press setups that support straight-cylindrical shank tooling with coolant-through capability.

Installation Notes

This bit is installed by machinists or toolroom personnel into compatible collet chucks or drill holders that accept a straight-cylindrical shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify coolant-through lines are clear and delivering adequate flow before beginning high-cycle operations. Do not exceed the maximum drilling depth of 47.95 mm (1.888 inches) per the flute geometry of this series.
