• Requires the use of RST 443R/L SET - seat when used on DSSNR/L tools and TSN 423-PIN SET seat when used on PSSNR/L-JHP and PSDNN-JHP tools

The inserts have 4 cutting edges (2 on each side) Advantages
with truncated radii – a configuration which facilitates • Increased cutting speed (due to better heat transfer)
heat transfer from the cutting area. 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
seat when used on DSSNR/L tools and TSN 423-PIN longitudinal and face turning
SET seat when used on PSSNR/L-JHP and PSDNN–
JHP tools. The standard seats should be replaced with Chipbreaking Range Chipbreaking Range
the special ones which have a pin whose purpose is to SNMG 120408-EM-M SNMG 120408-EM-R
prevent using the non-working flat cutting corners.
