Seco 02562785 Indexable Threading Toolholder Internal Rh

Product Description

The SECO 02562785 is an indexable threading toolholder designed for internal threading and turning operations on CNC lathes and turning centers. Built from steel with a right-hand orientation, this toolholder accepts 16NR-style inserts and uses a clamp-style insert holding method for secure, repeatable positioning. The shank measures 0.902 inches in height by 0.957 inches in width, with an overall length of 8 inches and a shank length of 5.748 inches. Coolant-through capability with axial concentric entry supports chip evacuation and thermal control during threading passes. This toolholder is part of the Snap Tap series and is suited for machinists and tool setters working in production threading environments.

This toolholder is used in internal threading and turning applications where bore access and insert reach are critical. The minimum bore diameter of 1.15 inches defines the smallest bore this tool can effectively enter. The CN-style toolholder geometry, combined with a 3/8-inch insert inscribed circle, makes it appropriate for medium-duty threading work in steel, cast iron, and similar materials. It fits standard boring bar setups on manual and CNC turning equipment and is flagged as a multi-use tool suitable for both threading and turning applications.

Compatibility

Compatible with 16NR-style inserts with a 3/8-inch inscribed circle. Also referenced under MSC/Manufacturer Number CNR/L 00100 8 to 16AHD. Designed for use in standard boring bar setups on CNC and manual turning equipment where a 1.15-inch minimum bore diameter is acceptable.

Installation Notes

Installation is performed by qualified machinists or tool setters on turning centers or lathes. Power down and lock out the machine spindle before mounting or changing the toolholder. Verify insert seating and clamp torque according to the machine shop's standard tooling procedures before initiating a cut. Confirm coolant line connection and flow before running coolant-through operation.
