Andy Walser, Productivity sales rep, in conjunction with the Productivity sales team and applications, evaluated Diamond Tools requirements, researched the best options, and performed test cut demonstrations. That along with Productivity’s strong reputation as a single source metalworking distributor offering machines, tooling, service and applications support, made the choice easy. Plus, it didn’t hurt that it had 60-position tool changer option that allowed for unattended operation.
