Guhring 9055150060000 Carbide Drill Bit 0.2362 in

Product Description

The GUHRING 9055150060000 is a solid carbide jobber length drill bit designed for high-performance drilling in ferrous materials. It features a 140-degree SU point angle with web thinning for self-centering entry, reducing the need for a center punch on most surfaces. The FIREX coating provides thermal and wear resistance, extending tool life in demanding production environments. With a 0.2362-inch diameter and a 5xD flute-to-diameter ratio, this bit delivers controlled chip evacuation through a regular spiral, two-flute geometry. Licensed tradespeople and machining professionals in metalworking and fabrication shops are the primary installers.

This drill bit is suited for drilling cast iron and steel workpieces in both production and job-shop environments. The straight-cylindrical shank seats directly into standard drill chucks and collet systems without adapters. The Series 5515 designation follows DIN 6537 L geometry standards, making it a recognized form factor in European-specification tooling applications. Maximum drilling depth is 35.00 mm (approximately 1.378 inches), keeping the bit in its optimal cutting range for jobber-length operations.

Key Features

• Solid carbide submicron-grade construction for hardness and rigidity in steel and cast iron
• FIREX coating for elevated-temperature and abrasion resistance
• 140-degree SU point with web thinning for self-centering entry
• Regular spiral, two-flute design promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Conforms to DIN 6535 and DIN 6537 L standards

Compatibility

Designed for use in drilling cast iron and steel workpieces; primary workpiece material codes K and P per DIN classification. Compatible with any spindle or drill chuck accepting a 6.00 mm straight-cylindrical shank.

Installation Notes

Installation and tool changes must be performed with the machine at a full stop and all power isolated. Seat the straight-cylindrical shank fully into the chuck or collet and verify runout before engaging the spindle. Use appropriate cutting fluid or dry-air blast where required by shop practice for cast iron or steel. Inspect the cutting edges and FIREX coating before each use; discard or resharpen if chipping or coating delamination is observed.
