Kennametal KCP25B
KCP25B is a Kennametal carbide insert grade (KENGold™ CVD), applied in the ISO P area. In this cross-reference it appears on 10 insert designations; 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.

The best-evidenced alternative to Kennametal KCP25B from another maker, with published cutting speeds (sourced, and compared only where both makers publish them for the same conditions), coating and what would decide a switch. Usually in your inbox within 30 minutes.
Kennametal KCP25B plus up to two grades you run next to it, worked through in one document: every cross-brand match with the number of manufacturer charts behind it, single-source candidates kept apart, where your grades overlap so the list can be shortened, and a validation plan. Emailed to you, usually within the hour. No account needed.
Same insert geometry, other brands
These makers produce the same insert designation in their own grade. Shared geometry is not a grade equivalence.

Frequently asked questions
What is Kennametal KCP25B?
KCP25B is a Kennametal carbide insert grade (KENGold™ CVD), applied in the ISO P area, used in 10 insert designations in this reference.
Which grades are comparable to KCP25B?
Grades from other makers confirmed at the same ISO application position by two or more manufacturer charts include Kyocera PR1225, Kyocera PR1725, Sandvik GC1525, Sumitomo AC1030U, ISCAR IC8250. 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.
