Carpenter Speed Star® High Speed Steel (Red-Hard) (AISI M2)
Categories:	Metal; Ferrous Metal; Tool Steel
Material Notes:	Speed Star high speed steel in a fine-grained "Moly"-Tungsten high-speed steel manufactured under close control. It has certain advantages over 18-4-1 high speed steels, some of which are lower cost, less weight per cubic inch, lower hardening temperature and somewhat easier machining. Applications: Lathe tools, Planer tools, Drills, Taps, Reamers, Broaches, Milling cutters, Form cutters, Thread chasers, End mills, Gear cutters, Wood knives Information provided by Carpenter Technology Corporation.
