Product Description

The TOOL-FLO 09495AC54F is a solid carbide laydown threading insert designed for cutting API Rotary Shoulder Connection threads at 4 threads per inch (TPI). The insert features an AlTiN coating applied via PVD process, which improves heat resistance and wear life during demanding threading operations. With a 5/8 inch inscribed circle and a 60-degree included angle, this insert handles both internal and external thread profiles. It is used by machinists and tool and die professionals working in oilfield and energy sector applications where API-standard threaded connections are required.

This insert is suited for threading operations on cast iron and steel workpieces in applications requiring API Rotary Shoulder Connection thread standards. The LDS54 insert style and AC54F manufacturer grade make it a direct fit for compatible laydown-style toolholders. With 2 teeth per side and a 4 TPI pitch, it is used in heavy-duty threading of large-diameter pipe and drill collar connections common in oilfield equipment manufacturing and service.
