APMT and APKT inserts are both 85° single-sided cutting tools with two cutting edges that are used to machine metals with precision. The strong geometry design enables to deal with alloy steel, stainless steel, and cast iron. It has the strong pocket design with excellent chip evacuation, extreme well ramping and slotting capabilities.
APMT inserts:
APMT inserts have an 85° parallelogram shape with an 11° back angle.
The “M” stands for the accuracy grade of the insert, which is molded grade accuracy.
APMT inserts with various coatings are suitable for machining steel, stainless steel, cast iron, non-ferrous metals, heat-resistant alloys, titanium alloys, and high hardness steels.
APKT inserts:
APKT inserts also have an 85° parallelogram shape with an 11° back angle.
The “K” stands for the grade of accuracy of the insert, which is a grinding grade of accuracy, higher than the “M” grade.
APMT VS APKT
The main difference between APKT and APMT inserts is their accuracy class. In both types of inserts, the “K” and “M” represent the accuracy level of the insert. Specifically, “K” grade accuracy is higher than “M” grade accuracy. Therefore, the workpieces machined by APKT inserts will have better surface finish and higher dimensional accuracy.
Additionally, the thickness of APKT and APMT blades may vary.
Overall, while APKT and APMT inserts may be similar in shape and design, they may perform differently in real-world applications due to differences in accuracy class and thickness. Therefore, when selecting an insert, you need to decide which one to use based on your specific machining needs and equipment conditions. I hope this information is helpful to you!
