Guhring 9055140091300 Screw Machine Drill Bit 23/64

Product Description

The GUHRING 9055140091300 is a screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built from solid carbide with a coated finish, this bit delivers the rigidity and edge retention that production and maintenance machinists demand in demanding applications. It features a 140-degree split point with SU geometry and web thinning for fast penetration and reduced thrust. The straight-cylindrical shank measures 10.00 mm in diameter, and the overall length is 89.00 mm (approximately 3.5 inches). Two spiral flutes with a regular helix and parallel web configuration promote efficient chip evacuation during drilling cycles.

This drill bit is suited for screw machine operations, CNC machining centers, and drill press applications where tight tolerances and consistent hole quality are required. Primary workpiece materials include cast iron and steel. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 1.311 inches (33.31 mm), it handles stub-length work in both production shops and field maintenance environments. It conforms to DIN 6537 K standards and is packaged as a single unit.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Secure the shank fully in a compatible chuck or collet before operation and verify runout before drilling. Power down the spindle completely before changing tooling. Do not exceed the maximum drilling depth of 1.311 inches without retracting to clear chips.
