Thread Grinder / Impregnated Dressers

American Diamond thread grinding tools are precision engineered and manufactured to give you long lasting, trouble-free service. Each stone is a tough, solid crystal of unmatched quality carefully selected for its sharp cutting points. Each stone is concentrically mounted by a special process in a powdered metal matrix that insures an unimpeded transfer of heat away from the cutting edge. All production operations are subject to constant supervision and every finished tool is rigidly inspected for accuracy and conformity to specifications by the shadow-graph and other advanced checking and inspection methods. The tools illustrated are available from stock in standard shanks for use on Ex-Cell-O, Jones & Lamson Thread Grinding Machines. Whatever your requirements, American Diamond engineers will design thread grinder dressing tools that are exactly right for your purposes.
