Seco 02562574 Indexable Threading Toolholder Internal Rh

Product Description

The SECO 02562574 is an indexable threading toolholder designed for internal threading and turning operations on CNC lathes and turning centers. It accepts two 16NR-style inserts and features a right-hand cutting orientation. The shank measures 0.65 inches in height and 0.707 inches in diameter, with an overall length of 6.693 inches. Coolant is delivered through an axial concentric entry port, directing fluid directly to the cutting zone for improved chip control and tool life. The insert is held by a clamp-style mechanism, providing rigid, repeatable positioning across indexing cycles. This toolholder belongs to the SECO Snap Tap series and is built from steel construction.

This toolholder is suited for internal threading and turning applications in both production and job-shop environments. It is typically installed in CNC turning centers by machinist-level trades or toolroom technicians. The minimum bore diameter it can reach is 0.95 inches, making it appropriate for medium-bore internal thread work. The insert inscribed circle is 3/8 inch, compatible with 16NR insert designations. The toolholder style is CN, and it supports multi-use configurations across threading and turning passes within the same setup.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CNC turning center tooling setups. Ensure the machine spindle and turret are fully powered down and locked out before inserting or removing the toolholder. Verify insert seating and clamp torque per the machine tool manufacturer specifications before running the first part. Confirm coolant line connection at the axial port is secure and free of obstruction before enabling through-tool coolant flow.
