Application Selection and Material Limitations
M2 is not interchangeable with D2 cold-work tool steel or general alloy round bar. Common uses include cutters, reamers, precision tools and wear tooling. Suitability depends on grade chemistry, dimensions, strength and condition, the working environment and any surface or dimensional specifications. A related material should not be substituted solely because its marketing name sounds similar.
Centerless Grinding and Bar Finishing
Mozaic Precision Metals can review sourcing and centerless grinding, bar straightening, polishing, chamfering, cut-to-length and packaging for this product. Specify starting size, finished OD and diameter tolerance, length, surface roughness, straightness and inspection requirements separately. Actual capability depends on the material condition and geometry.
