Sandvik Coromant 6408302 CAT50 to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408302 is a CAT to Capto taper adapter designed to interface a CAT50 outside taper spindle with a C5 inside Capto modular connection. This adapter allows shops running CAT50 spindle machines to use Capto-compatible tooling without changing the machine spindle. It features through-coolant capability, delivering coolant directly to the cutting zone for improved chip evacuation and tool life. With a 30mm projection and 50mm nose diameter, it provides a compact, rigid connection suited to high-precision turning and milling applications. Installation is typically handled by a machinist or toolroom technician as part of a toolholder setup.

This adapter is used in machining centers and turning centers equipped with CAT50 spindle interfaces where Capto modular tooling systems are being adopted or integrated. The through-coolant feature makes it well suited to deep-cavity, high-speed, or hard-material cutting operations where flood coolant alone is insufficient. Overall length of 131.80mm makes it appropriate for standard toolholder stacks without excessive overhang.

Key Features

• CAT50 outside taper mates directly with CAT50 spindle interfaces
• C5 inside Capto modular connection for use with Capto tooling
• Through-coolant design delivers coolant to the cutting zone
• 30mm projection keeps toolholder stack compact and rigid
• 50mm nose diameter provides stable Capto clamping interface
• 131.80mm overall length suits standard machining center setups

Compatibility

Designed for use with CAT50 spindle machines requiring a transition to C5 Capto modular tooling connections. Compatible with through-coolant capable spindles.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is powered down and all motion is fully stopped before handling or seating the adapter. Mating tapers and clamping surfaces should be cleaned and inspected for damage or contamination before assembly. Follow the machine tool and tooling manufacturer torque and retention force guidelines for CAT50 toolholders when securing the drawbar connection.
