Sumitomo TPMT321ELB AC8020P – Turning Carbide Insert

The Sumitomo TPMT321ELB turning carbide insert, featuring the AC8020P grade with a tin coating, excels in interrupted cutting applications on steel workpieces, where its triangle shape and 60-degree cutting edge provide robustness and stability. With a 0.0157″ corner radius and precise Absotech finish, this insert is well-suited for withstanding the stresses of interrupted cuts, making it an ideal choice for machining operations that involve frequent changes in cutting direction. Its compact size, with a 0.3750″ inscribed circle and 0.6496″ length, also allows for efficient material removal in tight spaces.
