415B Steel Hardness Tester
The instrument consists of a completely redesigned chassis made from aerospace aluminum, which houses a high quality displacement gauge. The upper end (the shank) is the gripping area for insertion into a milling machine, drill press, or lathe. The lower end is the load cell. It extends up into the body of the hardness tester and houses a center less ground precision spring which preloads the hardened steel indenter.
