Tool-flo S1252154AC50C Threading Insert 6 Tpi Carbide AC50C

Product Description

The TOOL-FLO S1252154AC50C is a solid carbide laydown threading insert designed for external Pittsburgh Acme thread cutting at 6 threads per inch (TPI). Manufactured in the AC50C grade and finished with an AlTiN (aluminum titanium nitride) coating applied via PVD process, this insert is built for threading operations that demand heat resistance and extended tool life. The 1/2-inch inscribed circle (IC) and L43 insert style make it a precisely dimensioned tool for use in compatible laydown threading toolholders. Machinists and tool-and-die professionals rely on this insert for consistent thread form on Pittsburgh Acme profiles.

This insert is suited for external threading operations on lathes and turning centers where Pittsburgh Acme thread forms are required. Pittsburgh Acme threads are commonly found in power transmission and mechanical actuator applications. The AC50C carbide grade with AlTiN finish provides performance in ferrous and hardened materials where surface heat buildup is a concern. This insert fits L43-style laydown threading toolholders and is sold individually with a minimum order quantity of 10 pieces.
