Sandvik Coromant 6408294 CAT40 to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408294 is a CAT40 outside taper to Capto modular taper adapter designed to bridge CAT40 spindle interfaces with Capto C4 inside modular connections. It provides a 60 mm projection length and a 40 mm nose diameter, making it a precision interface component used in CNC machining centers. The adapter supports through-coolant delivery, which directs cutting fluid directly to the tool tip for improved chip evacuation and tool life. It is installed by machinists and tooling setup technicians on machining centers equipped with CAT40 spindles where Capto tooling is required.

This adapter is suited for use in production machining environments where operators need to run Capto C4 modular tooling systems from an existing CAT40 spindle without retrofitting the machine. Typical applications include turning centers with live tooling, horizontal machining centers, and vertical machining centers running high-pressure coolant setups. The 128.40 mm overall length accommodates standard tool reach requirements in most CAT40 setups. Installation is performed during tooling changeover or workholding configuration by qualified tooling technicians or CNC setup personnel.

Key Features

• CAT40 outside taper interfaces directly with standard CAT40 spindle tapers
• C4 Capto inside modular connection enables use of Capto tooling system heads
• Through-coolant capability supports high-pressure coolant delivery to the cutting zone
• 60 mm projection and 128.40 mm overall length suit standard CAT40 reach requirements
• 40 mm nose diameter provides a robust clamping surface for Capto C4 modules
• Weighs 2.48 pounds for manageable handling during tooling setup

Compatibility

Designed as an OEM-style interface adapter for CNC machining centers with CAT40 spindle connections requiring a Capto C4 inside modular connection. No specific model compatibility data was provided in the available product information.

Installation Notes

Installation should be performed by a qualified tooling technician or CNC setup operator. Power down and lock out the machining center spindle before mounting or dismounting any taper adapter. Clean the CAT40 spindle taper and adapter mating surfaces thoroughly before seating to ensure proper contact and runout accuracy. Follow the machine tool manufacturer torque specifications for drawbar retention when securing the adapter in the spindle.
