There are Ball Indenters offered by us that are attached to a hardness testing machine called a hardness tester, and then a load is applied to press it into the test material. The hardness of the test material is determined by the depth or area of the indentation. The tip of the indenter is made of diamond or steel balls, and diamond indenters are used for testing hard materials and thin objects. Ball Indenters are very effective and made for commercial uses.
We supply 1/16" , 1/8" , 1/4" , 1/2" , 2.5mm, 5mm & 10mm Ball Indenters for Rockwell, Brinell & Vickers Hardness Testers
