ISO P Steel Turning Grade Cross-Reference
A brand-neutral cross-reference for ISO P (steel) turning insert grades from 7 manufacturers: ISCAR, Kennametal, Mitsubishi, Sandvik, Seco, Tungaloy and Walter. The 26 grades below are listed with their coating, ISO area and manufacturer-stated application range, ordered from finishing (P05) to roughing (P50) so you can line up each brand's grades across the steel-turning range. A shared application range is a starting point, not a drop-in replacement: substrate, coating, chipbreaker and edge prep differ between brands. Verify on a sample part before switching a production tool.
How to read this chart
- Application range
- The ISO P number (P05 finishing → P50 roughing) is the manufacturer's stated working range, not a hardness or a cutting speed. Several brands print overlapping ranges — that is normal.
- "Equivalent"
- Grades with a similar range are candidates with comparable application coverage, not certified drop-in replacements. Coating, substrate, chipbreaker and edge geometry still differ.
- Before you switch
- Trial the candidate on a sample part and check tool life, chip control and surface finish against your current grade. Ask the AI advisor for cutting data for your exact material and machine.

Cross-reference a grade at its ISO position
Type any maker's grade (e.g. GC4325, AC820P, T9215) to see grades other brands publish at the same ISO application position. VERIFIED = multi-source consensus; 2+ CHARTS = placement confirmed by two or more manufacturer-published charts; SINGLE-SOURCE = one chart only. Comparable at ISO position — not identical performance. Verify on a sample part.
Frequently asked questions
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.
