PLEASE READ FULL DESCRIPTION BEFORE PLACING ORDER!

No matter how much better your aftermarket miter saw dust collection works compared to the factory setup, it does nothing to collect the debris that gets forced below the saw's table.

So, where does all that debris go?

Some of it falls to the floor and under the saw. But a surprising majority of it gets ejected BEHIND the collector via the throat plate. This is especially true when cutting wide material, since the collector moves with the saw blade, further away from the back of the saw where the dust is ejected. In fact, depending on the size of the material you're cutting, so much dust escapes through the rear of the throat plate that it may seem like your aftermarket dust collection isn't working that great to begin with.

Enter the Dust Collection Throat Plate for the DeWALT DWS779 and DWS780 sliding miter saws.

This replacement throat plate has a built-in shroud that surrounds the blade under the table, guiding all the debris to the rear of the saw. And once there, a specially designed vacuum port sucks it all away via a clear vinyl tube connected to your vacuum or extractor.

It is meant to be used in tandem with aftermarket dust collection units that use a 1-5/8" outside diameter hose cuff. And to make it even better, it also uses replaceable, sticky-back, PVC tape for a zero clearance insert to provide you with safe, clean cuts.

What's included?

  • Throat Plate/Shroud. This will come as two pieces, a front section and a rear section. It replaces the factory throat plate and installs reusing the factory screws.
  • Throat Plate Vacuum port. This installs on the rear section of the throat plate with four small screws (included) and a 2mm hex (Allen) wrench (not included).
  • Clear Vinyl Hose. This is what carries the dust away. It connects the throat plate vacuum port to the vacuum adapter.
  • Vacuum Adapter. This is what allows everything to work together. On the vacuum side you can hook up to almost any extruder, shop vacuum or even a dust collector. It will accept 2-1/2" dust collection hose, 2-1/2" shop vacuum hose, 1-7/8 shop vacuum hose or 36mm Festool antistatic hose. On the tool side there are two ports. One port is to hook up the 1-5/8" hose cuff from your aftermarket behind-the-blade unit. The other port is sized to fit the supplied 1/2" outside diameter vinyl hose OR can be used with 5/8" inside diameter hose (not included or available from us). All fittings are tapered to provide a secure connection to a wide variety of brands of hoses, both new and old.
  • Zero Clearance Tape. This is what will give you the benefits of a zero clearance insert. It is sticky-backed and removable/replaceable, and the throat plate is recessed so that the zero-clearance tape will sit flush to the surface.
  • Rail Stops. In the event that the vinyl hose interferes with your aftermarket dust collection, the two 45mm-long rail stops can be snapped onto the saw's rails to prevent it from sliding all the way back. Unlike the rail lock on the DWS780, this will still allow the rails to fully extend.

The orange pieces shown in the photos are a prototype of a different product and will not be shipped with the Dust Collection Throat Plate!

NOT INTENDED FOR BEVEL CUTS! The throat plate and dust shroud are intended to be used with the blade at 90 degrees to the table. You can enjoy dust-free, quality cuts at any miter angle your saw was designed to make, but bevel cuts will destroy the throat plate and the vacuum port.

WORKS WITH THIN & FULL KERF BLADES! Designed with just the right amount of clearance to account with the flex that can happen when not pulling perfectly straight down and forward with the handle.

NOT GUARANTEED TO FIT ANY MODEL OTHER THAN DEWALT DWS779 & DWS780 SLIDING COMPOUND MITER SAWS!

This setup is intended to work with aftermarket dust collection systems that use a 1-5/8" outside diameter hose cuff (the piece that would be connected to a dust collector or vacuum hose). It can also be used with the factory dust collection tube, although we cannot guarantee it will make much a difference with the factory dust collection.

The throat plate sections, vacuum port, vacuum adapter and rail stops are 3D printed with PETG filament.

Excellent quality product. Completely eliminated dust on my miter saw. Highly recommend this to anyone serious about dust collection.

Dust port and shroud for Dewalt miter saw

I installed the shroud and port per instructions but for some reason I’m getting more saw dust around my miter station than I was before the install. Makes no since to me because it looks like it should work well with my shop nation dust port. I also have a very strong shop vac connected so I should have ample air to pull through both ports. Any suggestions would be welcome. Thanks

Wish I found this one earlier

Between allergies and family requests, having exceptional dust collection is more of a priority than when I was in a work shed. I've tried many capture add-ons, with many improving things, but where they all seem to fail is the throat plate. Usually, stuff gets thrown below the deck, causing chips and bits to build up and smaller particles to escape. After a few days, a thin 'wood dust' coats half the shop, proving other designs are only marginally effective. Meanwhile, the Inspire Woodcraft solution traps virtually all of the fine debris. Installing doesn't take long.

One benefit that should be highlighted matters for those who use a yellow zero clearance tape. Those tapes are thick enough to alter the level of a workpiece, especially smaller parts. The Inspire Woodcraft product maintains a flush-cutting surface. If I had all the money I spent on other guys' solutions, I could have paid for two of these, so if you're on the fence, let me tell you this is the best thing on the market today.
