Guhring 9055110050000 Carbide Drill Bit 0.1969 in

Product Description

The GUHRING 9055110050000 is a solid carbide jobber length drill bit designed for precision drilling in ferrous materials. Built to DIN 6537L standards, it features a 140-degree split-point (SU) tip geometry with web thinning for self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance during high-speed drilling cycles. At 3.2283 inches overall length with a 1.7323-inch flute length, this bit is suited for production and maintenance drilling where hole quality and tool life are critical. It is installed and used by machinists, tool-and-die professionals, and industrial maintenance technicians.

This drill bit is designed for use in cast iron and steel workpieces. Its 5xD flute-to-diameter ratio and coolant-through capability make it well suited for deep-hole drilling applications in CNC machining centers and production drilling equipment. The straight-cylindrical shank and regular spiral flute support consistent chip evacuation and accurate hole entry in both manual and automated setups. Conformance to DIN 6535 and DIN 6537L ensures dimensional interchangeability with standard toolholders used in industrial machining environments.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• FIREX coating for improved thermal resistance and reduced built-up edge
• 140-degree SU point with web thinning for self-centering entry
• Coolant-through design supports chip evacuation in deep-hole drilling
• Straight-cylindrical shank per DIN 6535 for standard collet and chuck compatibility
• Right-hand cut, regular spiral flute for consistent chip flow

Compatibility

Designed for use in cast iron and steel workpieces. Straight-cylindrical shank per DIN 6535 fits standard drill chucks and collet toolholders accepting a 0.2362-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and within tolerance before seating the shank. Coolant-through setups should be verified for adequate flow pressure before beginning a drilling cycle. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper feeds, or use in hand-held drill applications.
