Finally a solution that replaces the terrible dust collection attachment on your Hercules 12" HE74 Compound Sliding Miter Saw! You will see a HUGE improvement in dust collection efficiency with this upgrade - all without losing ANY effective saw capacity! This chute is printed in a blue color (close to the Hercules Blue) high strength PETG plastic with black PETG accessories.
NOTE: This solution is designed SPECIFICALLY for the HE74 model number. There is no guarantee that this will fit any other saw.
Everything you need is Included:
(1) Dust Collection Chute Body (Hercules Blue)
(1) Expanding Hose Section
(2) Flexible rubber flap
(1) Hose Transition Piece (with optional adapters if ordered)
(4) Small phillips screws for attaching flap to the chute body
(1) Install Card with QR Code for complete installation video
There is an option to add a dust collection fitting to accommodate the common dust collection hose sizes.

Works with |
| Hose Transition | 1.625" (41.2mm) | 1.4" (35.5mm) | Small extractor hoses, Festool D27 |

If you're in desperate need of some cleanliness in your shop, look no further! This product was meticulously designed and tested to optimize dust collection efficiency while not impacting the capacity of the saw itself.
Blade changes: To change your blade you will need to loosen the (2) mounting screws to allow enough wiggle room to get the blade off. This minor inconvenience was a necessary evil to keep safety and dust collection efficiency as high as possible!

Overall rating: 4.8 / 5 from 6 reviews.

It works.

I installed it per instructions and connected the HF dust extractor up. Made a metal bracket to zip tie the vac hose over the main spring of the miter saw. The hose needed some support I thought. Made a few cuts and frankly a little disappointed thinking this would capture more of the wood dust. I may need to build some type of hood around the cutting area. Overall this is better than the bag supplied method which comes with the saw.

Works well, i did note that if you haven't pushed out the top of the fence then it gets stuck and cuts the floppy sweep bit. Good that there were two :) it's been working well so far.

Dust collection on my Hercules double bevel miter saw from the factory was an afterthought at best, but more likely a cruel engineer's enduring nose thumbing at the folly of consumerism. It collects nothing but mounting disappointment. This gem from Wittworks, however, is an elegant and extremely effective solution which (in my limited use) collects the vast majority of sawdust from the blade regardless the use case (miter angle, bevel, slide engagement). I am very pleased to have this dust collector, and while I rarely write reviews, this product deserves to be crowed from the rooftops.

Straight forward installation with use of the video tutorial. Function is everything I hoped for.
