Stainless steel turning insert grades
CVD grade: new ultra-thin alumina coating and nano-columnar MT-TiCN with high-toughness cemented carbide substrate, special surface treatment technology effectively reduces cutting resistance and inhibits the generation of chip tumour, effectively improving the wear resistance of the grade.
PVD grades: High aluminium nano-structured coatings with different types of fine-grained cemented carbide substrates ensure stable machining of various types of stainless steel working conditions.

Class M (stainless steel) turning grades
GM1115\GM1230\GM3215\GM3220\GM3225
 |
●Combined nano-columnar MT-TiCN, thin Al2O3, bright TiN and a gradient substrate gives excellent wear resistance, low-stress posttreatment provides less built-up-edge and longer tool life.
●Recommended for finishing to semi-finishing of stainless steels. ●Applicable to Negative S series,Negative L series, Positive N series ,etc. |
| GM1115 | |
 |
●Thiner Al2O3 layer and nano-columar MT-TiCN layer with a gradient substrate. Post-treatment to reduce cutting force and less built-up edge, which in order to enhance the stability.
●Recommended for continuous and lightly interrupt processing in stainless steel. ●Applicable to Negative S series,Negative L series, Positive N series ,etc. |
| GM1230 | |
 |
●Brand new PVD TiAlN coating combined with submicron grained WC-Co cemented carbide substrate, provides the new grade with excellent wear resistance and heat resistance.
●Recommended for finishing of stainless steels and heat resistant alloys in stable cutting conditions at medium speeds. ●Applicable to Negative S series,Negative L series, Positive N series ,etc. |
| GM3215 | |
 |
●New nano-structured PVD coating matching high cobalt cemented carbide substrate, gives the grade with excellent wear resistance and high hot hardness.
Recommended for Continuous and light or medium Intermittent of stainless steels and soft steels at medium to low cutting speeds. ●Applicable to Negative S series,Negative L series, Positive N series ,etc. |
| GM3220 | |
 |
●The combination of optimized TiAlN coating and submicron grained carbide substrate with high Co content, provides superior adhesion and toughness.
●Recommended for semi-finishing of stainless steels and threading of steels, stainless steels, etc. ●Applicable to Negative S series,Negative L series, Positive N series ,etc. |
| GM3225 |
