SKILSAW SPT99 Worm Drive Table Saw Dust Port Size and Vac Adapter
The SKILSAW SPT99 is a 10 in. worm drive table saw. A table saw throws more chips than any other tool in the shop. Rip a few boards and the floor behind the saw turns white. Sealing the rear port is the single biggest dust win you can get.
The saw has a round dust port at the rear. A community adapter made for this saw lists the port near 2-1/4 in., which is about 57 mm inside. That puts it in the same class as the jobsite table saws. A 2-1/2 in. shop vac hose looks close, but it sits loose on a port this size. Loose means it leaks right where the saw makes the most dust. A GulpDust PETG adapter is printed to match the port on one end and your hose on the other end, so the joint seals and the chips go into the vac. No tape. No clamps. Measure your port first to confirm the fit.

SKILSAW SPT99 Dust Port Size: About 2-1/4 in. Round Rear Port
The rear dust port on the SPT99 is round. A community adapter built for this worm drive saw lists the port near 2-1/4 in., which is about 57 mm on the inside. That is the same class as most jobsite table saws.
This number comes from a community source, not from SKILSAW. So treat it as a strong starting point, then measure your own port before you order. Ports can shift a little between model runs.
Here is the trap. A standard 2-1/2 in. shop vac hose is named for a size close to this port, so people push the hose on, feel it wiggle, and reach for the duct tape. The hose cuff and the port were never made to seal on each other. A GulpDust adapter grips the port on one end and your vac hose on the other end, so the seal is tight and the suction stays at the blade.
How to Connect a Shop Vac to the SKILSAW SPT99
Unplug the saw first. Then wipe the sawdust off the rear port, so the adapter seats clean and seals all the way around.
Measure the port before you buy, since the size we list is from a community source. Then press the saw end of the PETG adapter onto the port. It is a friction fit, so a firm push is all it takes. Press your shop vac hose onto the other end.
Turn the vac on before the blade touches wood. A table saw fires chips down through the blade slot the moment the cut starts, so the vac needs to be pulling from the first inch.
Why Worm Drive Table Saw Dust Collection Matters
A worm drive saw has the torque to rip long, so it makes chips by the foot. One sheet of plywood can fill a vac drum. Pulling the dust at the port keeps it off the floor and out of the air.
The fine dust is the real problem. It floats, you breathe it, and it settles on every flat surface in the shop. Trapping it at the port keeps your lungs and your shop cleaner.
If you cut a lot, add a cyclone separator between the saw and the vac. The heavy chips drop into a bucket, so your vac filter stays clear and the suction stays strong.
SKILSAW SPT99 Dust Collection FAQ
What size is the dust port on the SKILSAW SPT99?+
A community adapter made for this saw lists the rear port near 2-1/4 in., which is about 57 mm inside. It is a round port at the rear. This is a community figure, so measure your port to confirm.
Will a 2-1/2 in. shop vac hose fit the SPT99 port?+
Not by itself. The hose cuff sits loose on a port this size, so it leaks and falls off mid cut. The GulpDust PETG adapter grips the port on one end and your hose on the other, so the joint seals tight.
Why should I measure the port myself?+
The size we list comes from a community adapter, not from SKILSAW. It is a strong starting point, but ports can shift between model runs. A quick measure with a ruler or caliper confirms the fit before you order.
Do I need clamps or tape to attach the adapter?+
No. The adapter is a friction fit. You push it on and it holds, so setup takes seconds and comes apart just as fast when you move the saw.
Can I print this adapter myself?+
Yes. You can buy the printed PETG part shipped from the US, or download the STL file and print it at home. We suggest PETG with 3 walls and 25 percent infill, so the part stays stiff and shrugs off shop heat.
