I hope this would do as state in the other review , but I be disappoint with several thing : it do not catch fine dust -lrb- mdf -rrb- at all because the dust just blow into the air from the air movement create by the saw blade ; if any of you wood be green , the moisture cause it to collect in the bag entrance and just stop all sawdust from get into the bag ; if you remove you blade guard to do dado and rabbet cut , the air flow that usually flow down from the saw blade be minimize already and attach this bag cause most of the airflow to go up around the blade along with most of the dust . if you use dry hardwood and little or no mdf or green wood , this will help to catch maybe 60 % - 70 % a of the sawdust , but I find myself do a lot of cut that require I to remove the blade guard which make this product almost useless - maybe 20 % of the dust be collect while the rest be throw into the air . I really think that the biggest problem be with the design of the lower blade cover in the saw design because it be not smooth and only the driest and heaviest sawdust get blow into this bag . Mark I down as disappointed and back to use my shop vac .
