Guhring 9055150046500 Carbide Drill Bit 4.65mm

Product Description

The GUHRING 9055150046500 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding materials. Built to DIN 6537L standards, it features a 140-degree split point (SU-type) with web thinning for self-centering entry and reduced thrust. The FIREX coating provides thermal resistance and extended tool life when cutting cast iron and steel. The submicron carbide grade and regular spiral flute geometry deliver consistent chip evacuation in production environments. At 74.01 mm overall length with a 36.01 mm flute length, this bit fits standard tool holders and CNC machining centers. Machinists, toolroom technicians, and production drilling operators are the primary users of this tool.

This drill bit is suited for production and job-shop applications where precision hole quality in ferrous metals is required. It performs in cast iron and steel workpieces, covering primary material codes K and P. The 5xD flute-to-diameter ratio supports drilling to a maximum depth of 29.03 mm without coolant-through capability, making it appropriate for short-to-medium depth holes in vertical machining centers, drill presses, or CNC lathes with driven tooling. Series 5515 designates this as a DIN 6537L long-series jobber geometry within the GUHRING catalog.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating reduces heat buildup and extends tool life in steel and cast iron
• 140-degree SU point with web thinning enables self-centering without a center drill
• Regular spiral flute geometry promotes consistent chip evacuation
• Straight-cylindrical shank at 6.00 mm diameter fits ER collets and standard drill chucks
• Conforms to DIN 6535 and DIN 6537L standards for dimensional consistency

Compatibility

Designed as a DIN 6537L jobber-length carbide drill for use in ferrous workpiece materials including cast iron and steel, compatible with standard straight-shank tool holders, ER collet systems, and CNC machine spindles accepting a 6.00 mm shank.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank in a properly sized ER collet or drill chuck with adequate clamping force before operation; never run a loose or improperly seated tool. Verify spindle speed and feed rate against published carbide tooling parameters for the workpiece material before engaging the cut. Inspect the cutting edges and coating condition before each use, as carbide tooling can fracture if run in a worn or chipped state.
