Guhring 9055100051600 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100051600 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding production environments. Built to DIN 6537K standards, it features a 140-degree split point (SU point type) with web thinning for reduced thrust and accurate self-starting entry. The 13/64 inch (0.2031 inch) diameter straight-cylindrical shank fits standard drill chucks and collets without modification. Two spiral flutes with a regular helix and parallel web configuration promote efficient chip evacuation. Coolant-through capability makes this bit well-suited for high-cycle CNC machining and screw machine operations where heat management is critical. Licensed HVAC techs, machinists, and tool-and-die professionals select this bit for its tight diameter tolerance and consistent performance in ferrous materials.

This drill bit is intended for drilling cast iron and steel in screw machine, CNC lathe, and automatic production applications. Its screw machine length body keeps deflection low in short-reach setups, and the 3xD flute-to-diameter ratio supports maximum drilling depths up to 25 mm. The coated carbide substrate maintains cutting-edge integrity across high-volume runs where high-speed steel bits would wear prematurely. It is appropriate for both light-duty repair shops and high-production manufacturing environments where repeatable hole quality in ferrous workpieces is required.

Key Features

• Solid carbide construction with submicron carbide grade for extended tool life in cast iron and steel
• 140-degree SU split point with web thinning reduces entry thrust and improves hole location accuracy
• Coolant-through design supports high-speed CNC and screw machine operation
• Straight-cylindrical shank with 6 mm shank diameter fits standard collets and drill chucks
• Meets DIN 6537K specification for consistent dimensional accuracy
• Diameter tolerance of +0.004 to +0.016 mm ensures precise fit in close-tolerance applications

Compatibility

Designed as an OEM-style replacement and production drill bit for screw machine and CNC applications targeting cast iron and steel workpieces, per Series 5510 and DIN 6537K classification.

Installation Notes

This bit is installed by machinists and tool-and-die technicians in CNC lathes, screw machines, or drill press setups. Ensure the machine spindle and collet or chuck are clean and within spec before seating the straight-cylindrical shank. Always verify coolant lines are clear and flow is established before engaging the cut when using the coolant-through feature. Handle carbide tooling with care to avoid chipping the cutting edge during loading and unloading.
