Look at the dust port on your DeWalt DCS520B. If it sticks out like a tube, measure the outside. On the DCS520B, if it is a hole, measure the inside. Use calipers.

Full port and fit detail for this tool
The DeWalt DCS520B is a 6-1/2 in. track saw. A track saw throws a fine line of dust right where you cut. Pulling that dust at the port keeps your line clean and the air clear.
The saw has a dust port at the rear. We print a GulpDust PETG adapter to your port measurement on one end and to your shop vac hose on the other end.

DeWalt DCS520B Dust Port: What Connects To It
The dust port on the DCS520B sits at the rear of the saw. We print the adapter to the size you measure there.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. Neither one seals on this port by itself. That gap is why dust sprays out instead of going into the hose.
A GulpDust adapter is printed to match the saw port on one end and your vac hose on the other end. The fit is snug, so the dust goes where it should.
How to Connect a Shop Vac to the DeWalt DCS520B
First, clear any dust out of the port. A clean port gives the best fit.
Press the tool end of the PETG adapter onto the port. We print it to the size you measure, so it holds with a firm push. Then press your shop vac hose onto the other end. Turn the vac on before you start the cut.
Why a Track Saw Needs Dust Collection
A track saw cuts fast and makes a lot of fine dust. That dust hangs in the air and lands on your track, where it can throw off the next cut.
Pulling the dust right at the port keeps the track clean and the air clear. You see your line, and you breathe easier.
DeWalt DCS520B Dust Collection FAQ
Will a GulpDust adapter fit the DeWalt DCS520B dust port?+
Yes. The port sits at the rear of the saw. We print the adapter to the size you measure there, and the other end matches your shop vac hose.
Does the DeWalt DCS520B work with a regular shop vac?+
Yes, with the right adapter. A shop vac hose and a tool port rarely match, so measure both. We print the GulpDust PETG adapter to your saw port measurement on one end and to your vac hose size on the other.
Do I need clamps or tape to attach the adapter?+
Usually not. We print the adapter to the size you measure, so you push it onto the port and it holds. The same goes for the vac hose end. Add a wrap of tape at any joint that sees heavy use.
Do you sell the design file?+
No. We sell the finished part. Each one is printed to order in PETG and ships from the US.
