Feed rate and RPM can vary depending on make of machine, water supply, material, operator and factory set up. If the RPM is engraved on the tool, it is the maximum RPM from the manufacturer, as the tool is legally required to show. We do not recommend running your tools at this RPM. The Feed Rate and RPM displayed on our website are recommended settings for optimal performance, as advised by our technical experts. You will need to adjust the Feed Rate and RPM to suit your specific individual setup to ensure safe and effective use, and best performance. If you are unsure on what these should be, please contact our technical team on technical@stonegatetooling.co.uk or you can arrange training at our Innovation Hub.
