Sandvik Coromant 5727288 Capto Weldon Shank Adapter

Product Description

The SANDVIK COROMANT 5727288 is a Capto to Weldon straight shank adapter designed to connect Capto modular tooling to Weldon-style straight shank setups on CNC machining centers and milling machines. It features a C4 outside modular connection with a 1/2 inch hole diameter, a 56 mm projection, and a 23 mm nose diameter, making it a precision interface component for shops running Capto quick-change tooling systems. Through-coolant capability delivers cutting fluid directly to the tool tip, supporting higher cutting speeds and extended tool life in demanding metal removal applications. This adapter is installed by CNC machinists and toolroom technicians working with modular tooling configurations.

This adapter suits production machining environments where Capto modular connections are paired with Weldon shank toolholders. It is appropriate for both roughing and finishing operations on machining centers requiring a secure, repeatable tool interface. The C4 connection size targets mid-range spindle platforms common in job shops and high-volume production facilities. Through-coolant routing makes it well suited for deep-cavity milling, long-reach applications, and heat-sensitive workpiece materials where flood coolant alone is insufficient.

Key Features

• C4 outside Capto modular connection for secure, repeatable tool mounting
• 1/2 inch hole diameter accepts standard Weldon straight shank tooling
• 56 mm projection provides clearance for deep-cavity and long-reach setups
• 23 mm nose diameter for compact spindle clearance in tight workpiece environments
• Through-coolant passage directs fluid to the cutting zone for thermal control and chip evacuation
• 80 mm overall length supports consistent gage-line to tool-tip measurement

Compatibility

Designed for use with C4 Capto modular tooling systems paired with 1/2 inch Weldon straight shank cutting tools. Specific machine and holder compatibility should be verified against the spindle interface and Capto connection size prior to installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machining center spindle before mounting or removing any toolholder or adapter. Verify that the Capto clamping unit is clean and free of chips or debris before seating the adapter, as contamination will affect runout and clamping force. Confirm through-coolant port alignment with the machine spindle coolant supply before tightening to ensure unobstructed flow.
