Sandvik GC1125 Equivalent Grades – Cross Reference Chart
GC1125 is a Sandvik PVD-coated carbide grade for turning. In published grade comparison charts it sits in ISO application ranges P20–P30, M20–M30, S20–S30 (steel and stainless steel and heat-resistant alloys and titanium). The table below lists the grades other manufacturers place in the same ranges, so you can find an alternative when GC1125 is out of stock, on long lead time, or a customer specifies another brand.

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.
