Sandvik Coromant 6039870 Coromant Capto Clamp

Product Description

The SANDVIK COROMANT 6039870 is a Cx-TRI-MS style clamp designed for use within the Coromant Capto modular tooling system. This component secures indexable inserts in Coromant Capto toolholders, maintaining precise cutting-edge positioning under the forces generated in turning, milling, and boring operations. The clamp corresponds to catalog number C4-TRI-MS40A and is built to the dimensional and clamping-force standards of the Coromant Capto interface. It is installed and serviced by machinists and toolroom technicians working with CNC and manual machine tools in production and job-shop environments.

This clamp is suited to shops running Coromant Capto C4-size toolholders where indexable insert replacement is a routine maintenance task. It is applicable in both high-volume production and precision low-volume work where consistent insert seating directly affects surface finish, dimensional accuracy, and tool life. The part ships individually (package quantity of one) and is intended as a direct replacement or spare component within an existing Coromant Capto tooling setup.

Key Features

• Cx-TRI-MS clamp style for secure indexable insert retention in Coromant Capto holders
• Corresponds to catalog number C4-TRI-MS40A for direct cross-reference
• Designed to maintain repeatable insert positioning across insert changes
• Compatible with the standardized Coromant Capto modular interface geometry
• Single-unit packaging supports targeted spare-parts stocking

Compatibility

Designed for use with Coromant Capto C4-size toolholders requiring the Cx-TRI-MS clamp style, as identified by catalog number C4-TRI-MS40A. Consult SANDVIK COROMANT toolholder documentation to confirm fitment before ordering.

Installation Notes

Installation and replacement of indexable clamps should be performed by a qualified machinist or toolroom technician with the machine in a safe, de-energized, and locked-out state per applicable lockout/tagout procedures. Use the correct Torx or hex key specified in the SANDVIK COROMANT holder documentation for the C4 interface — do not substitute driver sizes, as improper tooling can damage the clamping screw or insert seat. Inspect the insert pocket and seating surfaces for chips or debris before fitting the new clamp. Follow the manufacturer's assembly sequence to ensure full seating and proper clamping force.
