Sandvik Coromant 5728213 Capto Weldon Shank Adapter

Product Description

The SANDVIK COROMANT 5728213 is a Capto to Weldon straight shank adapter designed to interface a C5 outside modular Capto connection with standard Weldon-style toolholding setups. The adapter features a 1-inch hole diameter, a 48.40 mm nose diameter, and an 84.99 mm projection from the gauge line. Through-coolant capability allows cutting fluid to be delivered directly to the tool tip, supporting longer tool life and better chip evacuation in demanding machining operations. This adapter is installed by machinists and tooling technicians on CNC machining centers and milling machines requiring modular quick-change tooling.

This adapter is suited for production environments running Capto modular tooling systems where a transition to a Weldon straight shank interface is required. It is a common fitment on horizontal and vertical machining centers equipped with C5 Capto spindle connections. The through-coolant design makes it appropriate for deep-pocket milling, high-speed finishing, and other operations where flood coolant alone is insufficient to reach the cutting zone. The overall installed length is 114.99 mm, which should be factored into tool-length offset programming.

Key Features

• C5 outside modular Capto connection interfaces directly with compatible C5 spindles
• 1-inch hole diameter accepts standard Weldon shank tooling
• 84.99 mm projection provides clearance for deep-reach applications
• Through-coolant capability delivers fluid directly to the cutting edge
• 48.40 mm nose diameter for secure, concentric clamping
• 114.99 mm overall length for accurate tool-length offset setup

Compatibility

Designed as an OEM-style modular adapter for CNC machining centers using a C5 Capto outside modular connection and requiring a Weldon straight shank interface.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked. Capto interfaces require proper torque applied to the clamping mechanism per the machine tool builder specifications — do not overtighten by hand estimation alone. Verify through-coolant passages are clear before assembly and confirm tool-length offsets in the machine controller after installation. Consult applicable machine tool and tooling system documentation before use.
