Sandvik Coromant 5728168 Capto Weldon Shank Adapter

Product Description

The SANDVIK COROMANT 5728168 is a Capto to Weldon straight shank adapter designed to interface a C5 outside modular Capto connection with Weldon-style straight shank toolholders. It features a 1/2 inch hole diameter, a nose diameter of 23 millimeters, and a projection of 59.99 millimeters, giving machinists a well-defined reach for tool positioning. Through coolant capability is built in, allowing high-pressure coolant delivery directly to the cutting zone. This adapter is intended for CNC machining centers and milling setups where Capto spindle interfaces need to accept Weldon shank tooling. Installation is performed by experienced CNC tooling technicians or setup machinists.

This adapter is suited for production and job-shop environments running C5 Capto-equipped machining centers that require compatibility with Weldon straight shank end mills or other cylindrical-shank cutting tools. The through coolant feature supports high-speed machining applications where chip evacuation and tool life are priorities. With an overall length of 89.99 millimeters and compact nose geometry, it fits within typical toolchanger envelope requirements on vertical and horizontal machining centers.

Key Features

• C5 outside modular Capto connection for secure spindle interface
• 1/2 inch hole diameter accepts standard Weldon shank tooling
• 59.99 mm projection for defined tool reach and setup repeatability
• 23 mm nose diameter for compact clearance in tight workholding situations
• Through coolant passage supports high-pressure coolant delivery to the cutting edge
• 89.99 mm overall length fits standard toolchanger pockets on C5-equipped machines

Compatibility

Designed for use with C5 Capto outside modular connection spindles. Accepts 1/2 inch Weldon straight shank cutting tools. No additional model-specific compatibility data was provided in the product documentation.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or setup machinist with the machine in an E-stop or powered-down state and spindle rotation fully inhibited. Ensure all mating Capto surfaces are clean and free of chips or debris before seating the adapter. Torque the clamping mechanism per the machine spindle manufacturer guidelines, not values specific to this adapter. Confirm through coolant fittings are properly seated and leak-free before resuming machining operations.
