Guhring 9055140096000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140096000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in ferrous materials. It features a 0.378 inch diameter, a 140-degree split point (SU type), and a web-thinned, parallel-web geometry that reduces entry thrust and improves chip evacuation. The two-flute spiral design runs right-hand cut with a straight-cylindrical shank. At 89 mm (3.504 inches) overall length, this stub-length bit delivers rigid, accurate hole-making in production and job-shop environments. It is used by machinists, tool and die technicians, and maintenance professionals who need precise, repeatable results in cast iron and steel.

This drill bit is suited for screw machine operations, CNC drilling centers, drill presses, and hand-held power tools where a short, stiff bit is required to maintain positional accuracy. Its primary workpiece materials are cast iron and steel, making it appropriate for general metalworking production, fixture fabrication, and component repair in industrial and commercial settings. The solid submicron carbide construction handles elevated cutting speeds and intermittent feed applications where high-speed steel tooling would wear prematurely. The coated finish further extends tool life in abrasive ferrous workpieces.

Key Features

• Solid submicron carbide construction for extended tool life in cast iron and steel
• 140-degree SU split point reduces walking and lowers thrust at entry
• Web-thinned parallel web improves chip flow and reduces heat buildup
• Screw machine (stub) length provides maximum rigidity and runout control
• Right-hand cut, straight-cylindrical shank compatible with standard drill chucks and collets
• Conforms to DIN 6537 K specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for applications requiring a 0.378 inch diameter screw machine length carbide drill bit conforming to DIN 6537 K within the 0.350 to 0.400 inch size range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify runout with a dial indicator when precision is required. Carbide is brittle — avoid side loads, interrupted cuts at excessive feed, and re-chucking a visibly chipped tool. Refer to GUHRING cutting data recommendations and applicable shop safety standards when setting spindle speed and feed rate for the target workpiece material.
