Guhring 9055140135000 Carbide Drill Bit 0.5315 in

Product Description

The GUHRING 9055140135000 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 with SU web thinning and a coated finish that extends tool life under demanding conditions. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With a 3xD flute-to-diameter ratio and parallel web configuration, this bit delivers consistent chip evacuation and dimensional accuracy. It is intended for use by machinists, tool-and-die professionals, and production shops requiring tight tolerances in cast iron and steel applications.

This drill bit is sized at 0.5315 inches in diameter and falls within the 0.5000 to 0.6000 inch diameter range of the GUHRING Series 5514 lineup. Its screw machine length profile makes it suitable for CNC machining centers, drill presses, and turret lathes where rigidity and short overhang are priorities. Primary workpiece materials are cast iron and steel. The 2-flute spiral design with regular spiral type supports efficient chip removal at production feed rates. Coolant-through is not supported on this model.

Key Features

• Solid carbide construction with submicron carbide grade for hardness and wear resistance
• 140-degree SU point with web thinning reduces entry force and improves centering
• Coated finish extends tool life when drilling cast iron and steel
• DIN 6537 K compliant geometry ensures consistent dimensional performance
• Straight-cylindrical shank compatible with standard chucks and collet systems
• Maximum drilling depth of 1.565 inches (39.75 mm) with 3xD flute ratio

Compatibility

Designed for use in CNC machining centers, drill presses, and turret lathes equipped with standard straight-shank toolholders. Primary workpiece materials rated by the manufacturer are cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and within tolerance before seating the shank to prevent runout. Carbide drill bits are brittle compared to high-speed steel and should not be used in hand-held drills or applications with significant lateral force. Follow machine manufacturer feed and speed guidelines for the specific workpiece material to avoid chipping the cutting edge.
