General characteristics of APMT and APKT milling plates
- made of hard alloys KB7080 and KB9080;
- they have a durable coating that increases resistance to temperature stress and wear;
- suitable for a wide range of metalworking operations: end milling, profile milling, ledge processing;
- the milling cutters are attached to the body using mechanical elements, which ensures quick and convenient replacement;
- To improve performance, Kobi plates are equipped with multilayer wear-resistant coatings applied by PVD (Physical Vapor Deposition) methods.
Coating allows you to:
- increase the service life of the tool;
- increase the allowable cutting speed;
- improve the quality of the treated surface;
- reduce cutting forces and heat generation;
- expand the range of processed materials.
Type specifics
- APMT
- the shape is rectangular with a positive front angle;
- the geometry provides easy entry into the material and reduces cutting forces;
- suitable for finishing and semi-finishing of steels and stainless steels.

- APKT
- rectangular shape with a chamfer on the cutting edge;
- reinforced cutting edge increases strength and durability under severe cutting conditions;
- optimal for roughing, including difficult-to-process materials.

Main advantages of using
- Versatility. They are suitable for various operations: end milling, profile milling, and ledge processing.
- Cost-effectiveness. Replaceable plates allow you not to change the entire tool - it is enough to replace a worn plate.
- High performance. The optimized geometry reduces vibration and improves chip removal.
- Durability. The wear-resistant coating extends tool life and reduces downtime for replacement.
Where are they used?
Kobi APMT and APKT plates are suitable for enterprises:
- the machine-building and machine-tool sector;
- aviation and automotive industries;
- production of molds and dies;
- repair and tool shops.
Selection recommendations
When choosing plates, it is worth considering:
- The material of the workpiece. ISO groups: P - steels, M - stainless steels, K - cast iron.
- The type of processing. Chip breakers are available for roughing (R/H), semi-finishing (M) and finishing (F) processing.
- The radius of the vertex. 0.2–0.4 mm - for finishing and thin walls, 0.8–1.2 mm - universally or for roughing.
- Plate size. Must match the milling cutter body.
Kobi APMT and APKT plates confirm the brand's reputation as a reliable tool manufacturer. Their sophisticated geometry and high-strength materials ensure stable operation and long service life. Choose a tool that you can trust!
