Guhring 9006580025000 Cobalt Jobber Drill Bit 2.5 Mm

Product Description

The GUHRING 9006580025000 is a cobalt jobber-length drill bit engineered for demanding metal-cutting applications. Measuring 2.5 mm (0.0984 inches) in diameter with a 2.25-inch overall length, this bit features a titanium nitride (TiN) coating and a parabolic flute geometry designed to promote efficient chip evacuation and reduce heat buildup during drilling. The 130-degree split point and web-thinned tip allow for positive engagement on hard materials without the need for a center punch in most setups. A right-hand cut and straight-cylindrical shank make it compatible with standard drill chucks. This bit is suited for machinists, maintenance technicians, and fabricators working in production or job-shop environments.

This drill bit is designed for use in cast iron and steel workpieces, covering a broad range of ferrous metals common in manufacturing, structural fabrication, and mechanical maintenance. The parabolic flute provides a 5xD flute-to-diameter ratio, supporting drilling depths up to 1.03 inches (26.25 mm). Conforming to DIN 338 standards, the 9006580025000 fits into workflows where consistent dimensional tolerance and repeatable performance across multiple holes are required. It is suitable for use in drill presses, CNC machining centers, and handheld electric drills with appropriate chuck capacity.

Key Features

• Cobalt construction with TiN coating for extended tool life in ferrous metals
• 130-degree split point with web-thinned tip reduces thrust force and improves hole entry accuracy
• Parabolic flute geometry promotes fast chip removal and reduces heat at the cutting edge
• Right-hand cut, straight-cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 338 specification for consistent diameter tolerance (-0.014 to 0.000 mm)
• Tapered web configuration with 5xD flute ratio supports maximum drilling depth of 1.03 inches

Compatibility

Designed for use in cast iron and steel workpieces per DIN 338 Series 658 specification. Fits any standard drill chuck accepting a 0.0984-inch (2.5 mm) straight-cylindrical shank.

Installation Notes

This bit is installed and serviced by machinists or maintenance technicians using standard drill chucks or collet systems. Ensure the machine spindle is fully stopped and power is disconnected before inserting or removing the bit. Use cutting fluid or coolant appropriate for the workpiece material to maintain coating integrity and extend tool life. Do not exceed the rated maximum drilling depth of 1.03 inches in a single pass without pecking to clear chips.
