How to read cermet insert codes, choose between KT20 and KCT25, set cutting parameters and diagnose tool failure — written from the Koves cermet catalogue and cutting tests.
A technical guide to cermet cutting tools: KT20 and KCT25 grades, ISO insert codes, chipbreaker selection, recommended cutting conditions, materials and troubleshooting.
How cermet, coated carbide and CBN compare in hardness, toughness, wear resistance, cost and typical applications, with a side-by-side comparison table.
When cermet turning can replace grinding, how the two processes compare on cost, flexibility, precision and surface finish, and where grinding still wins.
A practical troubleshooting guide to cermet insert failure modes - chipping, built-up edge, notch wear, thermal cracking, chatter and chip control - with causes and corrections.
How to choose between the uncoated KT20 and the nano-AlTiN coated KCT25 cermet grades: coating effects, continuous versus interrupted cutting, and steel versus stainless.
Tell us the material, hardness and machine — our engineers reply with a grade recommendation and starting cutting data, at no obligation.
