The two edges • Reduced notch wear (due to 45º approach angle) without chipbreakers (flat) are not used. • Increased feed (the 45° approach angle produces a thin chip) • Increased productivity of up to 50% Toolholders • Ability to machine in two directions with the same tool, These inserts require the use of RST 443R/L SET - special longitudinal and face turning seat when used on DSSNR/L tools and TSN 423-PIN SET seat when used on PSSNR/L-JHP and PSDNN– Chipbreaking Range Chipbreaking Range JHP tools.
