Guhring 9055110047000 Carbide Jobber Drill Bit No.13

Product Description

The GUHRING 9055110047000 is a solid carbide jobber-length drill bit designed for precision drilling in demanding industrial and machining applications. Built to DIN 6537L standards, this bit features a 140-degree split-point (SU) geometry and a FIREX coating that extends tool life when cutting through cast iron and steel. The straight-cylindrical shank measures 0.2362 inches in diameter and the overall length is 2.9134 inches (74 millimeters). With coolant-through capability and a web-thinned, tapered web configuration, it is engineered for high-performance, self-centering cuts. Licensed machinists and tool-and-die technicians are the primary installers and operators of this bit.

This drill bit is suited for use in CNC machining centers, drill presses, and manual milling setups where tight-tolerance holes are required in ferrous materials including cast iron and steel (material codes K and P). The No. 13 wire gauge size corresponds to a decimal diameter of 0.1850 inches. The 5xD flute-to-diameter ratio and 36-millimeter flute length support chip evacuation in deeper blind and through-hole operations. It is a single-piece unit sold individually and is appropriate for production and maintenance machining environments.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in ferrous materials
• FIREX coating provides heat and oxidation resistance, extending tool life in steel and cast iron
• 140-degree SU split-point geometry enables self-centering entry without a center punch
• Coolant-through design supports internal coolant delivery for deep-hole drilling and heat management
• Web-thinned tapered web reduces thrust force and improves chip flow
• Conforms to DIN 6535 and DIN 6537 L standards for consistent dimensional accuracy

Compatibility

Designed as a high-performance replacement-style jobber drill for CNC and manual machining setups requiring a No. 13 wire gauge (0.1850 inch) solid carbide bit compatible with straight-shank toolholders. Primary workpiece materials are cast iron (K) and steel (P) per DIN material classification.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling procedures. Ensure the machine spindle and toolholder are clean and properly torqued before seating the straight-cylindrical shank. Carbide drill bits are brittle compared to HSS and must not be subjected to side-loading or used in hand-held drilling applications. When using the coolant-through feature, verify that coolant pressure and flow rate are appropriate for the machine before beginning the cut.
