Guhring 9055110054000 Carbide Drill Bit 5.4 Mm Firex

Product Description

The GUHRING 9055110054000 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537L standards, it features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The 5.4 mm diameter cutting edge is finished with a FIREX coating that extends tool life when working through abrasive or hardened materials. With a regular spiral flute and tapered web configuration, chip evacuation stays consistent through the full drilling depth. Licensed machinists and CNC operators working in job shops or production facilities are the primary installers of this tool.

This drill bit is engineered for cutting cast iron and steel, matching material grade codes K and P. It suits horizontal and vertical machining centers, drill presses, and CNC lathes running coolant-through tooling setups. The 5xD flute-to-diameter ratio and 35.90 mm maximum drilling depth make it appropriate for medium-depth through-hole and blind-hole applications in ferrous materials. The straight-cylindrical shank seats securely in standard ER collets or drill chucks sized for a 6 mm bore.

Key Features

• Solid submicron carbide substrate for rigidity and wear resistance in ferrous materials
• FIREX coating reduces friction and extends tool life in cast iron and steel
• 140-degree SU point with web thinning enables self-centering without spotting
• Coolant-through design channels fluid directly to the cutting edge
• Regular spiral flute with tapered web for consistent chip evacuation
• Conforms to DIN 6535 and DIN 6537 L standards for shank and length geometry

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for machining setups requiring a DIN 6537L jobber length drill in the 5.00 mm to 6.00 mm diameter range. No specific machine model compatibility was provided by the manufacturer for this listing.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before changing tooling. Confirm the collet or chuck bore matches the 6 mm straight-cylindrical shank diameter and that runout is within acceptable tolerance before initiating a cut. Engage coolant-through supply at the recommended flow rate for the workpiece material before starting the spindle.
