Sandvik Coromant 6078860 Capto Weldon Shank Adapter

Product Description

The SANDVIK COROMANT 6078860 is a Capto to Weldon straight shank adapter designed to connect a C6 Capto outside modular connection to a Weldon-style straight shank toolholder. It provides an 85mm projection and accepts a 1-inch hole diameter, making it suitable for shops that need to bridge Capto-style spindle interfaces with Weldon shank cutting tools. The nose diameter measures 48.4mm. Through-coolant capability is built in, directing coolant to the cutting zone for improved chip evacuation and tool life in demanding machining operations. Licensed machinists and toolroom technicians install this adapter as part of a modular tooling setup on CNC machining centers.

This adapter is used in CNC turning, milling, and machining center applications where a C6 Capto modular connection is present on the spindle or turret and the operator needs to run a Weldon straight shank tool. Through-coolant support makes it well suited for deep-reach operations, high-speed cutting, or materials that generate significant heat at the cutting edge. The 85mm projection and 123mm overall length give adequate clearance for workpiece access in many fixturing situations.

Key Features

• C6 outside modular Capto connection for direct spindle or turret mounting
• 1-inch hole diameter accommodates standard Weldon straight shank tools
• 85mm projection length for extended reach applications
• 123mm overall length for predictable gage-line planning
• 48.4mm nose diameter for stable tool engagement
• Integrated through-coolant path for improved chip evacuation and thermal management

Compatibility

Designed for use with C6 Capto outside modular connection spindles and turrets on CNC machining centers requiring a Weldon straight shank interface.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with modular tooling systems. Power down and lock out the machine spindle before mounting or removing the adapter. Ensure all mating Capto surfaces are clean and free of chips or debris before assembly, as contamination at the interface affects runout and clamping force. Follow the machine tool builder torque recommendations for the Capto clamping mechanism when securing the adapter.
