What is Kennametal KCM25B?
KCM25B is a Kennametal carbide insert grade (MT-CVD TiCN/Al₂O₃), applied in the ISO M area, used in 1 insert designation in this reference.
Which grades are comparable to KCM25B?
Grades from other makers confirmed at the same ISO application position by two or more manufacturer charts include Walter WSM20S, Sandvik GC2220, Seco CP500, ISCAR IC6025, Kyocera CA6525.

Does this cross-reference favour specific brands?
No. Comparable grades appear here only because manufacturer-published comparison charts place them at the same ISO application position. No manufacturer pays for placement, nothing on this page is sponsored, and CuttingToolsAI sells no tools and earns no commission. Placements backed by a single chart are flagged as such, and every comparison ends the same way: verify on a sample part before switching.
