Guhring 9055140031000 Screw Machine Drill Bit 0.122in Carbide

Product Description

The GUHRING 9055140031000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built to DIN 6537 K standards, it features a 0.122-inch diameter, a 140-degree split point (SU type), and a web-thinned, parallel web configuration that reduces entry force and improves centering accuracy. The two-flute spiral design promotes chip evacuation, and the coated finish extends tool life in abrasive materials. This bit is suited for machinists, tool-and-die professionals, and maintenance technicians working with precision drilling equipment.

The 9055140031000 is engineered for drilling cast iron and steel in screw machine and short-hole applications. Its screw machine length profile makes it a practical choice for turret lathes, CNC machining centers, and drill presses where rigidity and repeatability matter. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With a flute-to-diameter ratio of 3xD and an overall length of approximately 2.44 inches (62 mm), it fits standard tooling setups without special adapters.

Key Features

• Solid carbide construction with submicron carbide grade for wear resistance in ferrous materials
• 140-degree SU split point reduces walking and improves hole entry accuracy
• Web-thinned parallel web lowers thrust force requirements
• Two-flute spiral design promotes efficient chip clearance
• Coated finish extends tool life in cast iron and steel
• Meets DIN 6537 K specification for screw machine length carbide drills

Compatibility

Designed for use in standard drill chucks and collet holders accepting a straight-cylindrical shank; primary workpiece materials are cast iron and steel as specified by the manufacturer for Series 5514.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before loading or removing the bit. Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before beginning a cut. Do not exceed the maximum drilling depth of 0.604 inches (15.35 mm) per pass without retracting to clear chips.
