Guhring 9055150044000 Carbide Drill Bit 4.4 Mm Firex

Product Description

The GUHRING 9055150044000 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding industrial applications. Built to DIN 6537 L standards, it features a 4.4 mm diameter, a 140-degree split point (SU type), and a FIREX coating that extends tool life in abrasive and hard materials. The two-flute, right-hand spiral design promotes efficient chip evacuation, while web thinning reduces entry force and improves self-centering performance. This bit is intended for use by machinists and tool-and-die professionals working on precision drilling operations in production environments.

This drill bit is suited for drilling cast iron and steel workpieces in both light manufacturing and heavy production settings. The 5xD flute-to-diameter ratio and a maximum drilling depth of 32 mm make it appropriate for moderate-depth holes in ferrous materials. The straight-cylindrical shank at 6 mm diameter seats reliably in standard drill chucks and collet holders. It conforms to DIN 6535 and DIN 6537 L specifications, making it a direct fit for tooling setups that require metric DIN-standard tooling.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in ferrous materials
• FIREX coating reduces heat buildup and extends service life in cast iron and steel applications
• 140-degree SU split point provides self-centering entry without a center punch in most setups
• Web-thinned tapered web reduces thrust load and improves chip flow at the cutting edge
• Right-hand spiral flute with regular helix angle promotes consistent chip evacuation
• Conforms to DIN 6535 and DIN 6537 L for dimensional standardization across metric tooling setups

Compatibility

Designed for use in cast iron and steel workpieces. Compatible with standard drill chucks and collet systems accepting a 6 mm straight-cylindrical shank. Meets DIN 6535 and DIN 6537 L dimensional standards for metric tooling compatibility.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual drilling equipment. Ensure the machine spindle and workpiece are properly secured before beginning any operation. Confirm chuck or collet runout is within acceptable tolerance before seating the shank, as excessive runout accelerates carbide wear. Do not use this bit without confirming the spindle speed and feed rate are appropriate for the workpiece material and bit diameter.
