Guhring 9055140051600 Carbide Drill Bit 0.2031 in

Product Description

The GUHRING 9055140051600 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537 K standards, it features a 140-degree split point (SU type) with web thinning for reduced thrust and improved centering. The 2-flute spiral design with a 3xD flute-to-diameter ratio promotes efficient chip evacuation. With a straight-cylindrical shank and submicron carbide construction, this bit suits precision drilling operations where dimensional accuracy and tool life are critical. Licensed tradespeople and machinists installing or maintaining metal fabrication equipment rely on this style of bit for consistent, repeatable results.

This drill bit is engineered for use in cast iron and steel workpieces, making it appropriate for production machining, maintenance repair, and fabrication environments. Its screw machine length format — shorter overall length than jobber bits — provides added rigidity and reduced deflection, which is especially advantageous in CNC machining centers, drill presses, and turret lathes where tool overhang must be minimized. The coated finish supports extended tool life in demanding applications.

Key Features

• Solid submicron carbide construction for high wear resistance in ferrous materials
• 140-degree SU split point with web thinning reduces drill thrust and improves hole entry accuracy
• 2-flute spiral configuration with 3xD ratio supports efficient chip clearance
• Screw machine length provides added rigidity and reduced deflection versus jobber-length bits
• Straight-cylindrical shank with 6.00 mm diameter for standard chuck compatibility
• Conforms to DIN 6537 K specification for consistent geometry and dimensional tolerances

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with standard straight-shank chucks and collets accepting a 6.00 mm shank diameter. Suitable for CNC machining centers, drill presses, and turret lathes operating within the specified drilling depth range.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Confirm chuck or collet runout is within acceptable limits before use, as excessive runout accelerates tool wear and degrades hole quality. Do not exceed the maximum drilling depth of 0.7980 inches without retracting to clear chips.
