Is the 65mm version compatible with Makita RT0701 or the DeWalt DW611 ?
Or need I take the 69mm version for compatibility with Makita RT0701 or the DeWalt DW611 ?
There should be an adapting sleeve delivered with every Shapeoko, but we will have to verify this with manufacturer.
If it is delivered, then yes, you should be able to use DeWalt or Makita, but only thing is that Dust Boot will not fit. In that case you should buy additionaly 65mm Dust Boot to fit Makita router.
