I have a 10" Dewalt mitersaw.It has a fitting or port on the back of the saw for a dust bag.Ive never used the dust bag but have had my shop vac hooked to it.The fitting isnt very big maybe 1 1/2" at most and will get stopped up.It would be a lot better if the fitting were bigger I have to reduce the shop vac hose down to be able to make the connection. Is their a better way? I am just wanting to reduce the saw dust somewhat.
