Seco 02562787 Indexable Threading Toolholder Internal

Product Description

The SECO 02562787 is an indexable threading toolholder designed for internal threading and turning operations on CNC lathes and boring bars. Built from steel with a right-hand cutting orientation, it accepts two 16NR-compatible inserts secured by a clamp-style holding method. The shank measures 1.339 inches in height and 1.427 inches in width, with an overall length of 12 inches. Coolant-through capability is included via axial concentric entry, supporting chip evacuation and tool life in deep-bore threading applications. Licensed machinists and CNC operators working in production turning environments will find this holder ready for direct setup.

This toolholder is suited for internal threading and turning on both ferrous and non-ferrous workpieces in production and job-shop environments. The 1.7-inch minimum bore diameter determines the smallest bore it can enter, making it appropriate for medium-to-large diameter internal thread work. It belongs to the SECO Snap Tap series and is configured for 3/8-inch insert inscribed circle (IC) inserts coded 16NR. The CN toolholder style and clamp insert holding method are standard in high-volume turning setups where insert indexing speed matters.

Key Features

• Internal threading and turning capability in a single right-hand holder
• Accepts 16NR inserts with 3/8-inch inscribed circle for standard thread profiles
• Clamp-style insert holding for secure, repeatable insert indexing
• Coolant-through design with axial concentric entry for improved chip control
• Steel construction for rigidity and vibration resistance in deep-bore applications
• Part of the SECO Snap Tap series for consistent insert-change workflows

Compatibility

Designed for use with 16NR-compatible indexable inserts with a 3/8-inch inscribed circle. Toolholder style is CN with a compatible insert size code of 2. Verify insert grade and thread profile designation separately based on workpiece material and thread standard.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Confirm proper insert seating and clamp torque per the insert manufacturer's specification before cutting. Connect the coolant supply line to the axial concentric entry port and verify flow before initiating the threading cycle.
