the 4000k must rank way up there with the world 's greatest sawdust disperse tool . my dust Collector be try and fail . it be now gather dust -lrb- pun intend -rrb- . it be a nice thing to look at and seem to fit ok , but you would not want to depend on it . I can not be certain with actual efficiency rating , but I would be shock if you could prove it capture even half the sawdust . get a REAL dust extractor with enough vacuum to suck the paint off the tablesaw stand , and you will be sure to collect 90 % of the saw 's by-product . the other 10 % will be up you nose unless you wear a paper mask . : - -rrb- but real man eat sawdust , do not they ?
