Guhring 9055100030000 Carbide Screw Machine Drill Bit 3mm

Product Description

The GUHRING 9055100030000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537 K standards, this bit features a 140-degree split point geometry with web thinning for reduced thrust and improved chip evacuation. The 3.00 mm (0.1181 inch) diameter bit uses a straight-cylindrical shank with a 6.00 mm shank diameter and delivers a flute length of 20.00 mm with a maximum drilling depth of 18.00 mm. Coolant-through construction supports high-duty-cycle applications. Right-hand cut with a regular spiral flute pattern. This bit is installed by machinists and CNC operators in precision metal fabrication and production drilling operations.

This drill bit is suited for production machining in both manual and CNC machine tool applications. Primary workpiece materials include cast iron and steel. The screw machine length body (overall length 62.00 mm) provides rigidity and runout control in tight-tolerance setups. The submicron carbide grade and coated finish extend tool life in high-cycle drilling environments. A 3xD flute-to-diameter ratio supports chip clearing in moderate-depth holes without pecking in most applications.

Key Features

• Solid carbide construction in submicron grade for wear resistance in steel and cast iron
• 140-degree SU point with web thinning reduces entry thrust and improves centering
• Coolant-through design supports high-feed, high-speed production drilling
• Coated finish extends tool life and reduces built-up edge
• DIN 6537 K standard ensures dimensional consistency for replacement and interchangeability
• Straight-cylindrical shank fits standard collet chucks and drill chucks without modification

Compatibility

Designed for use in CNC machining centers, drill presses, and screw machines equipped with standard collet or drill chuck toolholding accepting a 6.00 mm straight-cylindrical shank. Optimized for cast iron and steel workpiece materials per series 5510 application guidelines.

Installation Notes

Installation and tool changes should be performed with the machine in a fully stopped and locked-out state per applicable machine safety procedures. Seat the straight-cylindrical shank fully into the collet or chuck and verify runout before beginning production. Coolant-through capability requires a machine spindle with internal coolant delivery for full performance benefit. Consult tooling manufacturer feed and speed charts for the specific workpiece material and machine before setting parameters.
