Guhring 9055150092500 Carbide Jobber Drill Bit 140deg

Product Description

The GUHRING 9055150092500 is a solid carbide jobber length drill bit engineered for precision drilling in demanding production environments. Built to DIN 6537L and DIN 6535 standards, this bit features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The straight-cylindrical shank seats securely in standard chucks and collets. With a 2-flute spiral design and tapered web configuration, it evacuates chips efficiently while maintaining rigidity through the cut. At 9.25 mm in diameter, it is sized for close-tolerance work, holding a diameter tolerance of 0.006 to 0.021 mm.

This drill bit is designed for machining cast iron and steel workpieces, corresponding to material codes K and P. It is a solid choice for CNC machining centers, drill presses, and manual machine setups where consistent hole quality and repeatable performance are required. The 5xD flute-to-diameter ratio gives it the reach typical of jobber length drilling applications in both job-shop and production environments. No coolant-through capability is present, making it suited for setups relying on external coolant or dry cutting.

Key Features

• Solid carbide construction for extended tool life in ferrous materials
• 140-degree SU point with web thinning for self-centering, reduced thrust force
• DIN 6537L and DIN 6535 compliant for standardized fitment
• Straight-cylindrical shank compatible with standard chucks and collets
• 2-flute spiral design with tapered web for efficient chip evacuation
• Diameter tolerance of 0.006 to 0.021 mm for close-tolerance hole making

Compatibility

Designed as a Series 5515 jobber length drill bit per DIN 6537L, suitable for use in cast iron and steel workpieces (material codes K and P) with standard straight-shank tool holders.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a matching collet or drill chuck before operation and verify runout is within acceptable limits before cutting. Carbide tooling is brittle and should not be subjected to side loading or interrupted cuts beyond its rated application. Inspect the cutting edges for chipping before each use and replace the bit if edge integrity is compromised.
