How to read ISO grade ranges
The letter is the workpiece group: P steel, M stainless steel, K cast iron, S heat-resistant alloys and titanium. A lower number (01–10) means a harder, more wear-resistant grade for higher cutting speeds and finishing; a higher number (30–40) means a tougher grade for interrupted cuts and roughing. Pick the equivalent from the same range as your current grade, then match the insert shape and chipbreaker.
Equivalents are approximate. This chart is compiled from the multi-brand grade comparison published in Tungaloy’s 2020–2021 general catalog, which is based on each manufacturer’s public catalogs and is not endorsed by them. Insert geometry and chipbreaker matter as much as the grade — send us your full insert model and we will confirm the closest match.
