Guhring 9055100078000 Screw Machine Carbide Drill Bit

Product Description

The GUHRING 9055100078000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built to DIN 6537K standards, this bit features a 140-degree split point with web thinning and a coated finish for improved wear resistance. The 7.80 mm (0.3071 inch) diameter and straight-cylindrical shank make it compatible with standard drill chucks and CNC machine tool holders. With coolant-through capability and a 3xD flute-to-diameter ratio, it is suited for high-speed, chip-clearing work in production environments. Licensed machinists, tool and die workers, and CNC operators are the primary installers.

This drill bit is engineered for cutting cast iron and steel in screw machine and short-hole drilling operations. The screw machine length body keeps the tool rigid in tight setups or where spindle clearance is limited. The spiral flute design promotes efficient chip evacuation during continuous drilling cycles. With a maximum drilling depth of 38.00 mm and a 2-flute regular spiral configuration, it handles repetitive production drilling where dimensional consistency is critical. The parallel web construction and submicron carbide grade support extended tool life in ferrous materials.

Key Features

• Solid carbide construction with submicron carbide grade for superior hardness and wear resistance
• 140-degree SU point with web thinning for accurate self-centering entry and reduced thrust
• Coolant-through design supports high-feed drilling and extended cycle times
• Coated finish reduces friction and extends tool life in cast iron and steel
• DIN 6537K standard compliance ensures dimensional consistency for production tooling
• Straight-cylindrical shank fits standard collets and drill chucks without adapters

Compatibility

Designed for use in CNC machining centers, screw machines, and drill presses equipped with standard straight-shank toolholders. Primary workpiece materials are cast iron and steel. Refer to GUHRING Series 5510 documentation for full application guidance.

Installation Notes

This tool is installed by machinists or CNC setup technicians following standard tooling change procedures. Power down and lock out the machine spindle before seating or removing the bit. Ensure the shank is fully seated and the collet or chuck is torqued to the machine manufacturer specification. Verify coolant-through lines are clear and flowing before beginning high-feed drilling cycles.
