Shear / scratch test set Taber Industries
115V/60Hz - 230V/50Hz

The Taber Shear / Scratch Tester is portable instrument is used to evaluate a material's or coating's resistance to shearing, scratching, gouging, marring, scraping or engraving. Specimens (up to 1/2" thick by 4" square) are affixed to a turntable and then a precision cutting tool, which is attached to a balanced and calibrated scale beam, is placed on the specimen. As the turntable rotates the specimen, the cutting tool will scratch or shear the specimen surface. A sliding weight adjusts the load applied on the scratch tool from 0 - 1000g to determine the point of failure. Optional interchangeable scratch tools include a conical diamond tool; diamond scratch tool; and 1.0 mm hemisphere scratch tip. Using the S-20 tungsten carbide tool (contour shear tool), Taber's Shear / Scratch Tester can also be used to evaluate coating adhesion on a variety of materials.
