Guhring 9055100056000 Carbide Drill Bit 0.2205 in 140 Deg

Product Description

The GUHRING 9055100056000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial applications. It measures 5.60 mm (0.2205 inches) in diameter with a 140-degree split point and a web-thinned, parallel web configuration that reduces thrust and improves chip evacuation at entry. The overall length is 66.00 mm with a 28.00 mm flute length and a maximum drilling depth of 25.00 mm. Built to DIN 6537 K standards, this bit is coated for extended tool life and features through-coolant capability, making it well suited for high-cycle production environments where heat and chip control are critical.

This drill bit is intended for use in cast iron and steel workpieces in machine shop and production line settings. The screw machine length format provides added rigidity compared to jobber-length bits, which reduces deflection in short-hole drilling on CNC machining centers, drill presses, and screw machines. The straight-cylindrical shank with a 6.00 mm diameter fits standard collet and drill chuck toolholding systems. It is appropriate for aerospace, automotive, and general metalworking applications where tight tolerances and consistent hole quality are required.

Key Features

• Solid carbide submicron-grade construction for superior wear resistance in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and self-centers on the workpiece
• Through-coolant design supports high-feed drilling and effective chip flushing in blind and through holes
• Coated finish extends tool life in cast iron and steel applications
• Regular spiral, 2-flute configuration provides efficient chip evacuation at a 3xD flute-to-diameter ratio
• Conforms to DIN 6537 K specification for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or direct substitute for screw machine length solid carbide drill bits conforming to DIN 6537 K with a 5.60 mm diameter and straight-cylindrical shank. Compatible with standard collet chucks and drill chucks sized for a 6.00 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool and die technicians familiar with CNC and manual machine tooling. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or chuck runout does not exceed manufacturer tolerances before seating the shank, as excess runout will accelerate wear and degrade hole tolerance. Through-coolant connections should be confirmed and flow verified prior to cutting to prevent premature tool failure in deep-hole applications.
