Used it to determine the hardness of a lathe tool holder, allowing for correct selection of a mill cutter that could cut it.

Performs as described. Using these hardness files to test hardness of annealed and heat-treated tool steels in my shop. Measures Rockwell C-scale hardness within a few points, not a precise testing tool but is not intended or advertised to test more precisely than plus or minus a few points of hardness. Certainly adequate for my purposes in tool making and woodworking.

Item came in nice package and was delivered within the timeframe stated. This set of tool is very helpful for checking hardness of parts/ tools in the workshop when a professional hardness tester is not available. The original instruction is in Japanese, but seller also includes a translated copy in English. Very thoughtful.Overall this is a good tool to be had in the home workshop, or for small family-own shops where having professional hardness testers are not practical.

While somewhat expensive, they are much cheaper than an actual Rockwell C hardness tester, and accurate enough for most machine shop needs. They are Japanese made. Use the tip to scratch or dig in to the metal piece in question. If it scratches or just digs in then your metal piece is softer on the Rockwell C scale. Move to the next lower probe until it does not scratch or dig in on your metal piece in question. You have now bracketed the hardness to within a 5 unit range on the Rockwell C scale. The whole process takes about 5 seconds per test range. Highly recommended for when tempering steel to a desired hardness, or when trying to identify the type and hardness of unlabeled scrap pieces.
