Guhring 9055100054000 Screw Machine Drill Bit 0.2126in

Product Description

The GUHRING 9055100054000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding production environments. It carries a 5.40 mm (0.2126 inch) diameter, a 140-degree split point angle, and a coated finish for extended tool life. The straight-cylindrical shank measures 6.00 mm in diameter, and overall length is 66.00 mm. Coolant-through capability supports high-feed drilling by delivering cutting fluid directly to the tip. A web-thinned, parallel-web construction reduces entry thrust and improves chip evacuation. This bit is intended for use by machinists and tool-and-die professionals in CNC and manual drilling operations.

This drill bit is rated for primary workpiece materials including cast iron and steel. The screw machine length geometry keeps the bit compact for rigid setups and close-tolerance work in turret lathes, drill presses, and machining centers. With a maximum drilling depth of 25.00 mm and a flute-to-diameter ratio of 3xD, it is well suited to short, high-precision holes in ferrous components. The two-flute spiral design promotes consistent chip flow and minimizes deflection during penetration.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance
• 140-degree SU point with web thinning for reduced thrust and self-centering entry
• Coolant-through design delivers fluid directly to the cutting edge
• Coated finish extends tool life in cast iron and steel applications
• Screw machine (stub) length for maximum rigidity in short-reach drilling setups
• Conforms to DIN 6537 K specification

Compatibility

Designed for use in CNC machining centers, turret lathes, and drill presses where a straight-cylindrical shank tool holder accepting a 6.00 mm shank is in use. Primary workpiece materials are cast iron and steel as specified by the manufacturer.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and all motion halted. Secure the straight-cylindrical shank firmly in a compatible collet or chuck to the tool holder manufacturer's specifications. Verify coolant-through lines are clear and flowing before initiating a cut. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the drill.
