The GCTS Specimen End Grinders provide the final step to prepare test specimens with parallel and flat ends according to ASTM and ISRM specifications. The grinders are driven by heavy-duty electric motors for durability and come with a 152 mm (6″) diamond cup wheel. Each grinder moves the specimen across the face of the grinding wheel, allowing the entire face of the specimen to be ground flat with a single pass.
GCTS also offers Specimen Core Drills, Specimen Lab Saws, and a Specimen Verification Kit to fully prepare a cylindrical rock specimen for testing.
