Product Description

Hardness Tester File Set

For use in all metal working & engineering facilities, comprising of six specially shaped precision files with curved tips, which can reach into internal slots, grooves and bores of parts which cannot otherwise be tested using conventional types of fixed or portable Hardness Testers. Useful for out-of-factory sites, large structures or segments of machinery. For example large surface-hardened gears, large printing cylinders or weld zones of heat affected pipe lines which cannot be moved to a stationary tester.
