Guhring 9055140127000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140127000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built to DIN 6537 K standards, this Series 5514 bit features a 140-degree split point with web thinning for reduced thrust and improved centering on entry. The straight-cylindrical shank measures 1.8503 inches and the overall tool length is 107 millimeters (approximately 4.21 inches). Submicron carbide grade and a coated finish extend tool life when cutting ferrous materials at elevated speeds. This bit is intended for use by machinists, tool-and-die professionals, and maintenance mechanics working in production or job-shop environments.

This drill bit is suited for screw machine operations and CNC drilling applications where short, rigid tooling reduces deflection. Primary workpiece materials are cast iron and steel. The 3xD flute-to-diameter ratio and parallel web configuration support chip evacuation in through-hole and blind-hole applications. The maximum drilling depth is 1.612 inches (40.95 mm). It is a single-piece unit sold individually.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree SU point with web thinning reduces entry thrust and improves self-centering
• Coated finish extends cutting edge life in cast iron and steel
• Right-hand spiral flute promotes consistent chip evacuation
• Screw machine length profile increases rigidity and reduces runout in short-reach setups
• Meets DIN 6537 K specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or production tooling option for screw machine and CNC drilling applications in cast iron and steel workpieces per Series 5514 specifications.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tool-and-die technicians with the spindle fully stopped and machine locked out per applicable safety procedures. Secure the straight-cylindrical shank in a compatible collet or drill chuck rated for the shank diameter before operation. Do not exceed the maximum drilling depth of 1.612 inches per pass without verifying chip clearance. Inspect the cutting edges and coating condition before each use to avoid premature failure or workpiece damage.
