Sandvik Coromant 5729964 Capto Weldon Shank Adapter

Product Description

The SANDVIK COROMANT 5729964 is a Capto to Weldon straight shank adapter designed to interface a Capto modular tooling connection with a Weldon-style straight shank holder. The C6 outside modular connection delivers a rigid, accurate mount for rotating tool assemblies in CNC machining centers and milling applications. Key dimensions include a 1-1/4 inch hole diameter, an 85.01 mm projection, and a 54.30 mm nose diameter, with an overall length of 123.01 mm. Through-coolant capability directs cutting fluid directly to the tool tip, supporting higher cutting speeds and longer tool life in demanding operations. Licensed machinists and CNC tooling specialists are the primary installers.

This adapter is suited for use in production machining environments where Capto modular tooling systems are already in place and a Weldon straight shank interface is required for a specific cutter or end mill. It is appropriate for both roughing and finishing operations on milling machines and machining centers where through-coolant delivery is beneficial. The C6 Capto size is typically matched to mid-to-large spindle platforms. No specific OEM machine model compatibility was provided in the product data.

Key Features

• C6 outside Capto modular connection for rigid, repeatable toolholder mounting
• 1-1/4 inch hole diameter accepts standard Weldon shank cutters
• 85.01 mm projection provides clearance for a range of workpiece geometries
• 54.30 mm nose diameter with 123.01 mm overall length for stable reach
• Through-coolant design delivers fluid directly to the cutting zone

Compatibility

Designed as an OEM-style adapter for CNC machining setups using C6 Capto modular tooling interfaces that require a Weldon straight shank output with a 1-1/4 inch hole diameter.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist. Power down and lock out the spindle drive before mounting or dismounting any toolholder. Inspect the Capto connection interface and Weldon bore for chips, burrs, or contamination before assembly, as debris will affect runout and clamping force. Verify through-coolant port alignment with the machine spindle coolant supply before placing the machine back into service.
