wow. a 0.7 mm bit would be just asking for me to break it. I snapped a 1.8" bit the other day by bumping the sled while it was running.
I struggle getting enough torque to release the collet with the router on the sled, so I really like the screw clamp that lets the router slide in and out quickly so I can swap bits off the sled relatively fast and drop it back in and twist it in place. Plus I pull the router and run it in its stock base for finishing cuts off the maslow as well.
