Seco 00043250 Indexable Turning Toolholder 1x1 Shank

Product Description

The SECO 00043250 is a right-hand SCLC-style indexable turning toolholder designed for use on CNC and manual lathes in general turning operations. It features a neutral rake angle of 0 degrees and a screw-lock insert holding method, which provides secure, repeatable insert clamping during cut. The toolholder accepts CC..43. series inserts, including the CCMT 432, and is built from steel for durability under continuous cutting loads. With a 1 inch by 1 inch square shank and an overall length of 5 inches, it is sized for standard toolpost and turret applications across a broad range of turning centers.

This toolholder is suited for external turning operations in both production and job-shop environments. The SCLC style with a -5 degree lead angle and right-hand cutting direction makes it appropriate for straight turning and light facing passes. The universal material compatibility rating means it can be used across a wide range of workpiece materials, from carbon steels and stainless steels to aluminum, cast iron, and superalloys. It is a single-use toolholder, not a multi-use or modular design, and is sold individually.
