Guhring 9055150058000 Carbide Jobber Drill Bit 0.2283in

Product Description

The GUHRING 9055150058000 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous metals. It carries a 140-degree split point (SU type) that self-centers on entry, eliminating the need for a center punch in most applications. The FIREX coating reduces friction and increases tool life, particularly in cast iron and steel. With a flute-to-diameter ratio of 5xD and a web-thinned, tapered web configuration, the bit handles chip evacuation efficiently during deeper passes. It is used by machinists, tool-and-die technicians, and industrial maintenance trades.

This bit is suited for drilling cast iron and steel workpieces in production and maintenance environments. The straight-cylindrical shank seats in standard drill chucks and collet holders with a 6 mm shank bore. The Series 5515 is built to DIN 6537 L and DIN 6535 standards, making it a direct fit for shops that spec to DIN tolerances. Coolant-through capability is not included in this variant. Typical applications include through-hole and blind-hole work in structural steel, machine frames, and cast iron housings.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard ferrous materials
• 140-degree SU split-point geometry self-centers on contact, reducing walk and setup time
• FIREX coating extends tool life and reduces heat buildup in cast iron and steel
• Web-thinned tapered web improves chip flow and reduces thrust at the cutting edge
• Right-hand spiral flute with regular helix for consistent chip evacuation
• Conforms to DIN 6537 L and DIN 6535 standards for dimensional consistency

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 6 mm straight-cylindrical shank. Intended for drilling cast iron and steel workpieces per primary material codes K and P. Conforms to DIN 6537 L specification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Follow machine tool manufacturer guidelines for spindle speed and feed rate when working with solid carbide tooling. Inspect the cutting edges before each use and remove from service at the first sign of chipping or excessive wear.
