Sandvik Coromant 5729944 Capto Weldon Adapter 1/2 in

Product Description

The SANDVIK COROMANT 5729944 is a Capto to Weldon straight shank adapter designed to connect a C6 Capto modular tooling interface to a Weldon-style straight shank tool holder. It provides a rigid, accurate transition between the two connection systems, maintaining concentricity and clamping force for milling and rotating applications. The adapter features a through-coolant channel, delivering coolant directly to the cutting zone for improved chip evacuation and tool life. With a 59.99mm projection and 23mm nose diameter, it fits standard machine spindle setups. Installation is handled by machinists and toolroom technicians working with modular tooling configurations.

This adapter is used in CNC machining centers and milling machines equipped with Capto C6 spindle interfaces that require compatibility with Weldon straight shank tooling. It is suited for shops running mixed tooling inventories where both Capto and Weldon-style holders are in use. The 1/2 inch bore accommodates standard Weldon shank cutting tools. The through-coolant feature makes it appropriate for deep-pocket milling, long-reach applications, or high-speed operations where flood coolant alone is insufficient to reach the cutting edge.

Key Features

• C6 outside modular connection for direct Capto spindle interface mounting
• 1/2 inch bore diameter accepts standard Weldon straight shank tooling
• 59.99mm projection supports extended reach tooling setups
• 23mm nose diameter for compact clearance in tight workpiece geometries
• Through-coolant channel directs coolant to the cutting zone
• Overall length of 97.99mm for predictable gauge-line calculations

Compatibility

Designed for use with C6 Capto modular tooling interfaces on CNC machining centers and milling machines that accept Weldon straight shank tool holders with a 1/2 inch bore.

Installation Notes

Installation of this adapter is performed by a qualified machinist or toolroom technician. Power down the machine spindle and relieve any coolant system pressure before mounting or removing the adapter. Ensure the Capto interface and mating surfaces are clean and free of chips or burrs before assembly to maintain proper seating and runout specifications. Verify through-coolant port alignment with the machine spindle coolant supply before operation.
