Selection of tools, steel analogues, coatings, hardness

5 tools

Section task: correctly match the material of the workpiece with the type, geometry and coating of the tool. Often this is the cause of half of the problems with wear and quality.

Recommends the type of cutting tool for a specific operation and material. Considers ISO group, hardness, operation and processing conditions.

Selection by ISO material

Classifies the workpiece material into ISO groups (P, M, K, N, S, H) and recommends the appropriate grades of carbide, geometry and modes.
