Zero Clearance Dust Port




Zero clearance inserts are wonderful for eliminating tearout, but unfortunately, they also impede dust collection. To give my collection system an opening to pull sawdust through, I cut a 1/2-in.-dia. hole at the front end of the blade slot. In this location, the hole doesn’t adversely affect the benefits of my zero clearance insert.

This is a great idea, exept, it doesn't help with the back of the blade where the teeth are coming up and can throw some dust back up and toward the operator.  If you put a similar opening at the rear of the blade, it will help to get some air flow at the rear of the blade to help with getting that dust prior to the teeth of the blade coming back up.
