DM20

The only core drilling motor on the market using PMSM Technology for the highest performance and 90% efficiency.

  • Water-cooled, high frequency PMSM motor has the highest output efficiency of any single phase coring motor on the market at 90%. Outstanding performance with large diameters up to 500 mm.
  • The Rebar Assist mode makes it much easier to handle embedded steel while drilling. When rebar is encountered, press the Rebar Assist button, once the steel is passed, press the button again to resume normal drilling mode.
  • LED display gives bit diameter, as well as mode display, service indicator, hours counter, and error codes.
