Guhring 9055150150000 Carbide Drill Bit 15mm 140 Series 5515

Product Description

The GUHRING 9055150150000 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding metalworking applications. Built to DIN 6537 L standards, it features a 15 mm diameter, a 140-degree split-point (SU) tip, and a FIREX multilayer coating that extends tool life in abrasive and hard materials. The submicron carbide grade provides rigidity and edge retention well beyond standard HSS tooling. With a 5xD flute-to-diameter ratio and a web-thinned, tapered web configuration, it delivers efficient chip evacuation and self-centering entry. Licensed machinists and CNC operators in production shops are the primary users of this bit.

This drill bit is designed for cutting cast iron and steel, including structural and alloyed grades. The spiral flute geometry and right-hand cut make it suited to both CNC machining centers and manual drill presses running moderate to high spindle speeds. The straight-cylindrical shank at 16 mm diameter seats in standard collet chucks or drill chuck holders. It is appropriate for use in job shops, automotive component manufacturing, mold and die work, and general metal fabrication where hole quality and tool life are priorities.

Key Features

• Solid submicron carbide construction for superior hardness and wear resistance
• FIREX coating reduces friction and extends tool life in ferrous materials
• 140-degree SU point geometry provides self-centering entry without a center punch
• Web-thinned tapered web improves penetration and lowers thrust force
• Conforms to DIN 6535 and DIN 6537 L standards for dimensional consistency
• No coolant-through design suited to flood coolant or dry cutting setups

Compatibility

Designed as an OEM-specification replacement or new-stock carbide drill for metalworking applications requiring a 15 mm straight-shank jobber-length bit conforming to DIN 6537 L geometry; compatible workpiece materials listed in specifications are cast iron and steel (material codes K and P).

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the collet or chuck bore is clean and free of chips before seating the 16 mm straight-cylindrical shank, and torque the toolholder to the machine manufacturer's specification. Always bring spindle to a full stop before changing tooling. Verify correct cutting direction (right-hand) and feed-and-speed parameters for the workpiece material before initiating a cut.
