Our most popular neck turner cutter is our standard steel. Made out of tool steel that get heat treated and then ground. We offer it in our universal 50 degree cutter and have 23, 28, 33, 38 and 43 degree cutters for those that want to be 3 degrees over their shoulder angle. The real benefit of the K&M Carbide Cutter is the useful life that is a multiple over the steel cutter. It also does better with heavier cuts. We will be introducing the carbide neck turner cutter in late summer/early fall with 23, 28, 33, 38 and 43 degree angles to go along with our standard 50 degree angle that it is today. Our large caliber cutters in both steel and carbide have 50 degree angles ground in them as standard.
