Kennametal KCU25
KCU25 is a Kennametal carbide insert grade (PVD AlTiN), applied in the ISO P/M/K/S areas. In this cross-reference it appears on 4 insert designations; the same insert geometry is also made by ISCAR, Sandvik, Seco, Tungaloy, Walter. 5 grades from other makers are confirmed at the same ISO position by two or more manufacturer charts. Same position is not the same performance: verify on a sample part before switching.

Frequently asked questions
What is Kennametal KCU25?
KCU25 is a Kennametal carbide insert grade (PVD AlTiN), applied in the ISO P/M/K/S areas, used in 4 insert designations in this reference.
Which grades are comparable to KCU25?
Grades from other makers confirmed at the same ISO application position by two or more manufacturer charts include ISCAR IC908, Mitsubishi VP15TF, Sumitomo AC1030U, Seco CP500, TaeguTec TT9080. Same position is not the same performance: treat them as starting points and verify on a sample part before switching.
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.
