I shot this video of the tool at JLC LIVE in Providence, Rhode Island. In it, Rick Bush of Festool describes the improvements they made to the saw. They include:
an improved bevel gauge
- a detent override for bevels greater than 45 and less than 0 degrees
- dual-depth scale for use with and without the guide rail
- a micro-adjust knob for fine-tuning depth-of-cut
- flat-sided blade housing that allows you to cut to within 1/2 inch of adjoining surfaces
Best of all, the saw comes with a peel-and-stick imperial scale (inches) that can be installed over the existing metric depth scale.
