Recommendations for Choosing RUIAN Carbide Inserts

Turning

For machining steel, the most popular grades are:

• RC6215 or RC6215D – high cutting speed, improved tool life under stable conditions; most popular with semi-finishing/finishing chipbreakers TG or TF.
• RC6225 or RC6225D – universal grade for machining steel, proven effective with semi-roughing chipbreaker GM; allows speeds up to 300 m/min and withstands minor impact loads.

For stainless steel (PVD):

• RP1020 – for unstable conditions and low cutting speeds, combined with semi-finishing/finishing chipbreaker TG.
• RP1225 – for high-speed machining of stainless steels from roughing to semi-finishing, combined with chipbreaker TM.
• RP9125B – suitable for machining 12Х18Н10Т (austenitic corrosion-resistant, heat-resistant, and heatproof stainless steel).

For machining cast iron (CVD):

• RC8305H – suitable for high-speed finishing of cast iron; ultrafine WC-Co grade, coated with Al2O3/MT-TiCN.
• RC8315A – universal grade for machining cast iron; medium-grain WC-Co grade, coated with Al2O3/MT-TiCN; proven effective with universal chipbreaker KM.

For grooving and parting operations:

• RP9125C – universal grade for machining steels and stainless steels.

Milling and Hole Machining

• RP9125B or RP9125C – both grades perform excellently in hole machining and milling of all steels up to 45 HRC.
• RP1020 – grade for rough machining of steel and stainless steel.
• RP1205 or RP9025 – grades used in mold manufacturing and machining of hardened steels up to 55–60 HRC.
