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.
The Model 415B is designed for use by inspection and quality control personnel, heat treaters, tool and die makers, mechanics, welders, etc. This unique instrument is the
handiest and the most economical way of grading and checking various metals in equivalent Rockwell B range of 40HRB to 100HRB.
