Guhring 9055150097000 Carbide Drill Bit 9.7 Mm Firex

Product Description

The GUHRING 9055150097000 is a solid carbide jobber-length drill bit engineered for high-performance drilling in ferrous metals. Built to DIN 6537L standards, it features a 140-degree split-point (SU) tip geometry with web thinning for self-centering entry without a center punch. The substrate is submicron-grade solid carbide finished with a FIREX coating, which extends tool life in demanding cast iron and steel applications. The 9.7 mm cutting diameter is paired with a 10 mm straight-cylindrical shank and a regular spiral flute pattern. Licensed machinists, tool and die setters, and CNC operators are the typical end users for a bit at this specification level.

This drill bit is designed for production drilling in cast iron and steel workpieces, referenced by material codes K and P. The 5xD flute-to-diameter ratio and 61 mm flute length support controlled chip evacuation at moderate-to-high feed rates. The 57 mm maximum drilling depth and 103 mm overall length suit it to vertical machining centers, drill presses, and CNC lathes running rigid toolholding. It performs without through-coolant, relying on the FIREX coating to manage heat at the cutting edge.

Key Features

• Submicron solid carbide substrate with FIREX coating for extended tool life in steel and cast iron
• 140-degree SU point with web thinning for self-centering entry
• Right-hand cut, regular spiral flute with 2 flutes for efficient chip evacuation
• Straight-cylindrical 10 mm shank conforms to DIN 6535 for standard collet and chuck compatibility
• 5xD flute-to-diameter ratio supports deeper holes without pecking in most setups
• Diameter tolerance of 0.006 to 0.021 mm for close-tolerance bore applications

Compatibility

Designed as an OEM-grade replacement or new-installation drill bit for any rigid toolholding system accepting a 10 mm straight-cylindrical shank, conforming to DIN 6535 and DIN 6537L specifications.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or CNC operators familiar with carbide tooling. Ensure the spindle and toolholder are fully stopped and locked out before loading or removing the bit. Solid carbide is brittle compared to high-speed steel — avoid lateral side loads, interrupted cuts without appropriate feed reduction, or drops onto hard surfaces. Verify runout at the shank before production drilling to stay within the stated diameter tolerance.
