Sandvik Coromant 6408380 Drill Chuck 0.5118 in Keyed Tapered

Product Description

The SANDVIK COROMANT 6408380 is a keyed drill chuck designed for precision drilling operations in machining and metalworking environments. It accepts drill shanks up to 0.5118 inches (13 mm) capacity and mounts via a tapered, modular connection shank with a C6 modular connection size. The plain bearing construction and steel chuck body provide reliable concentricity and durability under continuous production loads. With a maximum spindle speed of 8000 RPM, this chuck is suited for high-productivity drilling on CNC machining centers and tooling systems that accept modular connection toolholders. Installation and tool changes are performed by licensed machinists or qualified tooling technicians.

This chuck is intended for use on machining centers, drilling machines, and modular tooling systems configured with a C6 modular connection interface. Its keyed design provides positive drill retention, making it appropriate for production drilling in steel, cast iron, aluminum, and similar workpiece materials. The tapered mount and modular shank interface allow for repeatable tool changes with consistent axial positioning. It is a direct fit for tooling setups where a C6 modular connection chuck is specified by the machine tool or toolholder manufacturer.

Key Features

• 0.5118 inches (13 mm) maximum drill chuck capacity for standard twist drill and jobber drill shanks
• Keyed chuck design provides secure drill retention during high-torque and high-RPM operations
• C6 modular connection shank for repeatable, accurate mounting on compatible tooling systems
• Rated to 8000 RPM maximum spindle speed for high-productivity drilling applications
• Steel chuck body construction for long service life in industrial machining environments
• Plain bearing type with closed length of 3.9764 inches and open length of 3.7402 inches for compact tooling envelope

Compatibility

Designed for use with machining centers and drilling systems equipped with a C6 modular connection toolholder interface. Verify that the host spindle or toolholder accepts the C6 modular connection shank before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular connection tooling systems. Power down and lock out the machine spindle before mounting or removing the chuck from the toolholder. Follow the machine tool manufacturer torque and clamping specifications for the C6 modular connection interface. Inspect the chuck and modular connection mating surfaces for burrs or contamination before assembly to ensure proper seating and concentricity.
