Sandvik Coromant 5729960 Capto Weldon Straight Shank Adapter

Product Description

The SANDVIK COROMANT 5729960 is a Capto to Weldon straight shank adapter designed to interface a Capto C6 modular connection with a Weldon-style straight shank toolholder. It accepts a 1-inch bore diameter and features through-coolant capability, directing cutting fluid directly to the tool tip for improved chip evacuation and tool life. With a projection of 85.01 mm and an overall length of 123.01 mm, this adapter provides a precise, rigid connection between the spindle and cutting tool. It is installed by toolroom technicians and machining setup specialists in CNC milling and turning environments where Capto modular tooling systems are in use.

This adapter is suited for use in machining centers and turning centers equipped with Capto C6 spindle interfaces. The Weldon straight shank output allows compatibility with a wide range of end mills, drills, and other cylindrical-shank cutting tools requiring a 1-inch bore. The through-coolant feature supports high-pressure coolant systems, making this adapter appropriate for production environments running demanding materials or deep-cavity work where flood coolant alone is insufficient.

Key Features

• Capto C6 outside modular connection for rigid, repeatable spindle coupling
• 1-inch bore diameter accepts standard Weldon-shank cutting tools
• Through-coolant design channels coolant directly to the cutting zone
• 85.01 mm projection with 123.01 mm overall length for extended reach applications
• 48.40 mm nose diameter provides a compact profile to minimize interference in tight setups

Compatibility

Designed as an OEM-style adapter for CNC machining centers and turning centers equipped with a Capto C6 spindle interface, used with Weldon straight shank cutting tools at 1-inch bore diameter.

Installation Notes

Installation should be performed by a qualified toolroom technician or CNC setup specialist. Ensure the machine spindle is fully powered down and the tool carousel or turret is in a safe, locked position before mounting or removing the adapter. Verify that the Capto C6 coupling surfaces and the Weldon bore are clean and free of chips or debris before assembly. Confirm through-coolant passages are clear and that the machine coolant system pressure is within the tool manufacturer's rated range before operation.
