Threading Grade introduction
GM3325/GM3225/GM3220/GAT7115/GAT7125
 |
● The newly upgraded PVD AlTiN coating, combined with a high Co fine-grained hard alloy matrix, provides excellent wear resistance and collapse resistance, which can be used for processing at various cutting speeds and feed rates
● Suitable for thread machining of stainless steel and steel under unstable working conditions ● Applicable to Un-grind thread series-TC |
| GM3325 | |
 |
● 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 Un-grind thread series-TC、High precision thread series、G-Notch series-thread |
| GM3225 | |
 |
● 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 Un-grind thread series-TC |
| GM3220 | |
 |
● New nanostructured PVD coating combine with micro-graincemented carbide substrate and special surface treatment,provides outstanding wear resistance, oxidation resistance andmachining stability.
● Suitable for steel and stainless steel in general cuttingcondition with medium or high speed. ● Applicable to GST series-thread |
| GAT7115 | |
 |
● New generation coating with new PVD technology,combinedwith high-Co cemented carbide substrate, provides excellenttoughness and cutting edge strength.
● Suitable for steel and stainless steel in unstable cuttingcondition. ● Applicable to GST series-thread |
| GAT7125 |
