Seco 02562797 Internal Threading Toolholder Right Hand

Product Description

The SECO 02562797 is an indexable internal threading toolholder designed for precision threading and turning operations on CNC lathes and boring machines. Built from steel with a right-hand orientation, this toolholder accepts 22NR inserts secured by a clamp-style holding method. The shank measures 0.902 inches in height and 0.957 inches in width, with an overall length of 7.917 inches. Coolant-through capability is supported via axial concentric entry, making it suitable for demanding production environments where thermal management and chip evacuation are critical. It is part of the Snap Tap series and carries a CN toolholder style designation.

This toolholder is suited for internal threading and turning applications in both production and job-shop environments. The minimum bore diameter of 1.2 inches defines the smallest workpiece bore it can access. With a head length of 1.736 inches and a center-to-cutting-edge dimension of 0.710 inches, it is configured for consistent insert positioning in deep-bore threading setups. Licensed machinists and CNC operators working with steel, alloy, and similar materials will find this toolholder a direct fit for standard internal thread-cutting cycles.

Designed to accept 22NR threading inserts with a 1/2-inch inscribed circle. Compatible with CN-style toolholder seat configurations. Verify insert geometry and grade selection against the target thread form and workpiece material before use.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and all axes at rest. Secure the toolholder in the turret or tool block to the machine manufacturer's specified clamping torque using calibrated tooling. Confirm insert seating and clamp engagement before resuming cutting operations. When routing coolant-through supply, verify that the machine's internal coolant system pressure and connector style are compatible with the axial concentric entry on this holder.
