Kennametal KCP30B
KCP30B is a Kennametal carbide insert grade (KENGold™ CVD), applied in the ISO P area. In this cross-reference it appears on 1 insert designation; the same insert geometry is also made by ISCAR, Mitsubishi, 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 KCP30B?
KCP30B is a Kennametal carbide insert grade (KENGold™ CVD), applied in the ISO P area, used in 1 insert designation in this reference.
Which grades are comparable to KCP30B?
Grades from other makers confirmed at the same ISO application position by two or more manufacturer charts include ISCAR IC8350, Kyocera PR1535, Mitsubishi VP20RT, Tungaloy UX30, ISCAR IC50M. 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.
