Guhring 9055150138000 Solid Carbide Jobber Drill 13.80mm

Product Description

The GUHRING 9055150138000 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and metalworking applications. Built to DIN 6537L standards, it features a 13.80 mm diameter, a 140-degree 4-facet point, and a multi-layer FIREX proprietary coating that extends tool life in abrasive and heat-generating cuts. The web-thinned, tapered web geometry reduces entry force and supports self-centering behavior at the point. With an overall length of 124.00 mm and a flute length of 77.00 mm, this drill is sized for consistent chip evacuation across a 5xD depth-of-cut envelope. Installation and operation are handled by machinists and tool-room technicians running CNC machining centers, drill presses, and manual lathes.

This drill is intended for use in ferrous and hard-material applications. Primary workpiece material categories include steel, cast iron, and stainless steel, corresponding to material codes P and K. The straight cylindrical shank at 14 mm diameter and 45 mm shank length fits standard ER and straight-bore collet systems. A maximum drilling depth of 70.00 mm makes it appropriate for through-hole and blind-hole work within its rated reach. This series is a catalog staple for job shops and production floors that require repeatable hole quality without coolant-through infrastructure, as the 9055150138000 does not require coolant-through capability.

Key Features

• Solid carbide submicron-grade construction for rigidity and edge retention in hard materials
• Multi-layer FIREX coating reduces friction and extends tool life in steel and cast iron
• 140-degree 4-facet point geometry provides self-centering entry without a pilot hole
• Web-thinned tapered web lowers thrust force and improves chip break at entry
• Regular spiral flute with 5xD flute-to-diameter ratio supports chip evacuation to 70.00 mm depth
• Straight cylindrical 14 mm shank fits standard collet and chuck systems
• Conforms to DIN 6535 and DIN 6537 L dimensional standards for interchangeable tooling programs

Compatibility

Designed as an OEM-spec replacement or direct procurement option for machining operations requiring a DIN 6537L jobber drill in the 12.50 mm to 15.00 mm diameter range, suitable for use in any machine spindle accepting a 14 mm straight shank.

Installation Notes

Installation is performed by machinists or tool-room personnel. Secure the straight shank fully in a collet, drill chuck, or hydraulic holder rated for the shank diameter before energizing the spindle. Confirm runout is within acceptable tolerance before beginning production drilling, as excessive runout accelerates carbide edge chipping. Do not use this drill beyond its rated maximum drilling depth of 70.00 mm without retracting to clear chips.
