Each diamond penetrator is mounted in conformity with its grain structure, to assure balanced pressure and prevent early wear or breakage.
They are precision ground, lapped and polished.
We also subject each diamond penetrator to a strict performance test before it is approved and accredited for sale.
Anvils help ensure accurate test results by supporting the test specimen during the application of the major load during a hardness test. Rockwell anvils are compatible with most Rockwell hardness testers.
