Guhring 9055140050000 Screw Machine Drill Bit 0.1969 in

Product Description

The GUHRING 9055140050000 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. It measures 0.1969 inches in diameter with a 140-degree split point (SU point type) and a web-thinned geometry that reduces entry force and improves hole accuracy. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 66.00 mm. With a 2-flute spiral configuration and a 3xD flute-to-diameter ratio, this bit delivers efficient chip evacuation in short-hole drilling applications. It is suited for use in CNC machining centers, drill presses, and screw machine setups where tight tolerances and tool longevity are required.

This drill bit is built for production environments where ferrous materials such as cast iron and steel are the primary workpiece materials. The screw machine length format provides added rigidity compared to jobber-length bits, making it a reliable choice for high-cycle drilling operations. The parallel web configuration and web-thinned point reduce walking and improve centering without a pilot hole in many applications. Machinists and tool-and-die professionals working to DIN 6537 K standards will find this bit fits standard toolholding systems with 6.00 mm shank compatibility.

Key Features

• Solid carbide submicron-grade construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces thrust and improves entry precision
• 2-flute spiral design with regular spiral type for efficient chip removal
• Screw machine length format provides superior rigidity over jobber-length bits
• Coated finish enhances wear resistance and surface lubricity
• Conforms to DIN 6537 K specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct application drill bit for use in CNC machining, screw machine, and drill press setups requiring a straight-cylindrical shank tool in the 0.1500 to 0.2000 inch diameter range per DIN 6537 K.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Ensure the machine spindle and toolholder are fully de-energized and at rest before inserting or removing the bit. Secure the straight-cylindrical shank firmly in a compatible collet or chuck to the toolholder manufacturer's specified clamping procedure. Do not exceed the maximum drilling depth of 0.8070 inches (20.50 mm) for this bit series.
