Guhring 9055150135000 Carbide Jobber Drill 13.50mm

Product Description

The GUHRING 9055150135000 is a solid carbide jobber-length drill bit designed for high-performance drilling in cast iron and steel. It features a 13.50 mm diameter (0.5315 inch), a 140-degree split-point (SU) geometry, and a FIREX coating that extends tool life in demanding production environments. The straight-cylindrical shank measures 14.00 mm in diameter and 45.00 mm in length, making it compatible with standard drill chucks and collet holders. With a 5xD flute-to-diameter ratio and web-thinned, tapered web construction, this drill is built for self-centering entry and efficient chip evacuation. It is installed by machinists, tool-and-die professionals, and maintenance technicians working with ferrous materials.

This drill bit is suited for through-hole and blind-hole applications in cast iron and steel workpieces in both production machining and job-shop environments. With a maximum drilling depth of 56.75 mm (2.234 inches) and an overall length of 124.00 mm, it fits standard CNC machining centers, knee mills, and drill presses where a straight-shank jobber drill is required. The FIREX coating provides thermal and wear resistance, making it appropriate for higher spindle speeds and dry or minimal-lubrication cutting strategies on ferrous materials. The 2-flute spiral design promotes reliable chip removal throughout the cut.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating provides thermal resistance and extended tool life
• 140-degree SU point geometry with web thinning for self-centering entry and reduced thrust force
• Straight-cylindrical shank (14.00 mm diameter) fits standard chucks and collet systems
• 5xD flute ratio supports drilling depths up to 56.75 mm without pecking in most applications
• Conforms to DIN 6537 L and DIN 6535 standards for dimensional consistency

Compatibility

Designed as a DIN 6537 L Series 5515 jobber drill for use in CNC machining centers, knee mills, and drill presses equipped with straight-shank toolholders accepting a 14.00 mm shank. Rated for primary workpiece materials cast iron (ISO K) and steel (ISO P).

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with carbide cutting tools. Confirm the spindle and toolholder are fully powered down and de-energized before loading or unloading the drill. Carbide drills are brittle compared to high-speed steel — avoid side loads, interrupted cuts without appropriate feed reduction, and re-sharpening without proper carbide grinding equipment. Verify runout and chuck concentricity before first use to prevent premature chipping.
