Product information for purchasing teams
Free-cutting steels contain added sulphur, and sometimes lead, so chips break cleanly and tools last longer on automatic lathes. EN1A is the common low-carbon grade; the leaded version machines faster still. EN8M is a free-cutting version of EN8 for stronger parts.
