Guhring 9055140076000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140076000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to DIN 6537K standards, this right-hand-cut bit features a 140-degree split point with SU point geometry and web thinning for fast, accurate starts with minimal thrust. The straight-cylindrical shank measures 1.496 inches and the overall tool length is 79 millimeters, making it a compact, rigid choice for screw machine and CNC setups. With a flute-to-diameter ratio of 3xD and regular spiral fluting, it handles chip evacuation efficiently in ferrous materials.

This drill bit is suited for production drilling in cast iron and steel across metalworking, machining, and fabrication environments. It fits standard screw machine and CNC drill press chucks accepting straight-cylindrical shanks. The 0.2992-inch diameter and screw machine length profile make it well-matched for close-tolerance work where stub-length rigidity is required. It does not feature through-coolant capability, so external coolant or cutting fluid should be applied when drilling at sustained high feeds and speeds.

Key Features

• Solid carbide submicron-grade construction for extended tool life in hard and abrasive materials
• 140-degree SU point with web thinning reduces entry thrust and walking on hard surfaces
• Coated finish for improved wear resistance and heat management
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Parallel web configuration maintains consistent geometry through the flute length
• Conforms to DIN 6537K specification for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with standard straight-cylindrical shank chucks; suited for drilling cast iron and steel workpieces within the 0.2500 to 0.3000 inch drill bit size range per Series 5514 specifications.

Installation Notes

This bit is installed by machinists and toolroom technicians in screw machines, CNC machining centers, or drill presses equipped with compatible chuck systems. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank firmly in the chuck to the full depth of the shank to prevent pullout under load. External coolant or cutting fluid should be applied during operation, as this tool does not support through-coolant delivery.
