Diamond Core Drilling Motors

The only PMSM 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.
• The separate LED Load Indicator, gives reliable information on load and thermal conditions.
• High Frequency Converter is integrated into the unit, so you can just plug it into the 230 V single phase supply and start drilling!
• The Bit Threading function makes threading on large bits much easier. Simply align the spindle with the bit, press the button once, and it will automatically rotate at low speed to thread the bit on. Press the button once again to stop.
• 17 Speed settings are easy to select, and can be adjusted on the fly. Device keeps memory of the most recent speed setting whenever it's plugged in.
