Guhring 9055110051100 Carbide Jobber Drill Bit Size 7

Product Description

The GUHRING 9055110051100 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It carries a wire size designation of 7 (0.2012 inches decimal) and features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The FIREX coating improves heat resistance and wear life in demanding applications. With an overall length of 82 millimeters and a 2-flute right-hand spiral configuration, this bit is suited for machinists, tool-and-die workers, and maintenance technicians running production or precision drilling operations.

This bit is built for drilling cast iron and steel, covering primary workpiece material codes K and P. It fits standard CNC machining centers, drill presses, and handheld power tools that accept a 6-millimeter straight-cylindrical shank. The 5xD flute-to-diameter ratio and 44-millimeter flute length support chip evacuation in deeper holes. Coolant-through capability makes it compatible with through-spindle coolant setups, extending tool life in continuous cutting cycles. Typical applications include production machining, fixture work, and maintenance drilling where dimensional accuracy and consistent hole quality are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating for elevated heat resistance and extended tool life
• 140-degree SU point with web thinning for self-centering entry
• Coolant-through design compatible with through-spindle coolant systems
• Right-hand spiral flute for efficient chip evacuation
• Meets DIN 6535 and DIN 6537 L standards for dimensional consistency

Compatibility

Designed for use in CNC machining centers, drill presses, and power tools accepting a 6-millimeter straight-cylindrical shank. Rated for drilling cast iron and steel workpieces per primary material codes K and P.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tool operator with the spindle fully stopped and the machine in a locked-out state per applicable safety procedures. Confirm shank diameter and collet or chuck size match before seating the bit. When using coolant-through capability, verify coolant pressure and flow settings are within the machine tool manufacturer specifications before running. Inspect the cutting edge and coating condition before each use and remove the bit from service at the first sign of chipping or excessive wear.
