Guhring 9055110041000 Carbide Jobber Drill 4.1 Mm

Product Description

The GUHRING 9055110041000 is a solid carbide jobber length drill bit designed for high-performance drilling in cast iron and steel. It carries a 140-degree split point (SU type) with web thinning for self-centering entry without a pilot hole. The FIREX coating improves wear resistance and extends tool life in abrasive materials. With an overall length of 74 mm (2.913 inches) and a flute length of 36 mm (1.417 inches), this bit fits standard straight-cylindrical toolholders and is suited for CNC machining centers and manual drill presses used in production environments.

This drill bit is built for machining cast iron and steel workpieces in applications where dimensional accuracy and tool longevity matter. The 5xD flute-to-diameter ratio and coolant-through design support deep-hole drilling at consistent chip evacuation rates. It follows DIN 6537 L and DIN 6535 standards, making it a direct fit in shops that specify DIN-compliant tooling. Series 5511 positions it within the GUHRING high-performance carbide drill lineup intended for production-level cut rates on difficult ferrous materials.

Compatibility

Designed for use in cast iron and steel workpieces per primary workpiece material codes K and P. Fits standard straight-cylindrical toolholders. Conforms to DIN 6537 L specification for jobber length solid carbide drills.

Installation Notes

This bit is installed by machinists and CNC operators using collet chucks or drill chucks rated for the 6 mm (0.2362-inch) straight-cylindrical shank diameter. Ensure the machine spindle and coolant-through system are verified before running at production feed rates. Confirm workholding is secure before engaging the cut. Do not run this bit in materials outside the rated cast iron and steel categories without consulting the manufacturer cut data.
