ISO application area

Recommendations

Steel shank cutter bodies are generally the first selection. Carbide shank cutter bodies are recommended for applications with highest demands on precision-machining.

Inserts

Use shallow axial and radial cuts for safe productivity. Always calculate the true cutting speed (v_e) based on the effective diameter in cut (D_e).
