ISCAR IC8250

IC8250 is a ISCAR carbide insert grade (SUMO TEC® CVD Al₂O₃), applied in the ISO P area. In this cross-reference it appears on 10 insert designations; the same insert geometry is also made by Kennametal, 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 ISCAR IC8250?

IC8250 is a ISCAR carbide insert grade (SUMO TEC® CVD Al₂O₃), applied in the ISO P area, used in 10 insert designations in this reference.

Which grades are comparable to IC8250?

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, Kennametal KCP25B. 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.
