Tsubosan Hardness Tester Set HRC40 to HRC65 175 mm MA00600

[Features] • Set of 6 testers; each hardness level is color-coded by its grip. • The grip is non-slip and fits comfortably in the hand. • To use, remove rust from the test material first, then press and rub with a tester. If it scratches the object, the hardness is below the value marked on that tester. • If no scratch is made, check with the next higher tester. The tips are bent, so hardness can be checked on flat, curved and inner surfaces. [Applications] • A measuring tool for easily testing hardness from HRC40 to HRC65. • Fits in a pocket; convenient for large workpieces or special steel outdoors that cannot be placed in a testing machine. • A set at hand is useful for checking workpiece hardness before machining or confirming the hardness reached after heat treatment.
