Product Description

The SECO 00018321 is a CL-style cantilever clamp designed for use with indexable toolholders in metal cutting and turning applications. This clamp secures indexable inserts within compatible toolholder bodies, maintaining precise insert positioning during cutting operations. It is part of the Secomax series and is engineered for toolholders with an insert dimension of 4. Installation is performed by machinists and toolroom technicians working with CNC and conventional turning equipment. The clamp accommodates left-hand, right-hand, and neutral cutting directions, making it a versatile replacement component for shops running multiple toolholder orientations.

This clamp is suited for use in production machining environments where indexable toolholder systems are standard. It fits a defined range of SECO toolholder styles and is sold individually, though the minimum order quantity is 10 units.

Installation Notes

This clamp is installed by a machinist or toolroom technician as part of routine insert indexing or toolholder maintenance. Before servicing any toolholder, confirm the machine spindle is fully stopped and the toolholder is secured in a vise or fixture. Use the appropriate torque wrench and clamp screw specified for the toolholder series to avoid over-tightening, which can damage the clamp seat. Inspect the clamp seat and insert pocket for wear or debris before installing the replacement clamp.
