Kobalt SM3055LW Miter Saw Dust Port Size and Shop Vac Adapter Guide
The Kobalt SM3055LW is a 10 inch sliding compound miter saw. A miter saw throws a big pile of chips on every cut. A vac at the port catches most of them before they land on your work and your floor.
The saw has a large round dust port at the rear. One community adapter reads about 52 mm on the inner bore, with a wider cuff of about 55.5 to 58 mm at the saw end. That is a single measurement, not a hard spec, so measure your own port with calipers before you buy. A GulpDust PETG adapter is sized to the port on one end and your shop vac hose on the other end. No tape. No clamps.

Kobalt SM3055LW Dust Port Size: Large and Round, About 52 mm Inside
The dust port on the SM3055LW is large and round. One community adapter listing puts the inner bore at about 52 mm and the saw-end cuff at about 55.5 to 58 mm. That is a stepped port, so the number you read depends on where you place the calipers.
Treat 52 mm as a close guide for the inner bore, not a hard spec. This is a single community measurement, not a caliper reading on our bench. Measure your own port before you order so you get the right size.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. A 2-1/2 inch hose is close to this large port but rarely seals on its own. A GulpDust adapter matches the saw port on one end and your vac hose on the other end for a tight fit.
How to Measure Your Kobalt SM3055LW Dust Port
Slide the inside jaws of your calipers into the port and open them out until they touch the inner wall. That gives you the inner diameter. You should read close to 52 mm on the main bore.
This port is stepped, so check the saw-end cuff too. Close the caliper jaws around the outside of the cuff for that reading. It runs wider, about 55.5 to 58 mm.
Write down both numbers and order the adapter to match. The inner bore is what the adapter plugs into, so that reading matters most.
Why Dust Collection Matters on a Sliding Miter Saw
A sliding miter saw makes a big pile of chips fast. Those chips spray back behind the fence and pile up on the bench and the floor.
Pulling the chips at the port keeps your work area clear and keeps the fine dust out of the air you breathe. It also helps you see your cut line so your cuts stay clean.
For the best result, match the adapter to the port and run a steady vac while you cut. Any shop vac with the right adapter does the main job.
Kobalt SM3055LW Dust Collection FAQ
What size is the dust port on the Kobalt SM3055LW?+
One community adapter reads about 52 mm on the inner bore, with a wider cuff of about 55.5 to 58 mm at the saw end. That is a single measurement, not a hard spec, so measure your own port with calipers before you buy.
Does the Kobalt SM3055LW work with a regular shop vac?+
Yes, with an adapter. A 2-1/2 inch shop vac hose is close to this large port but rarely seals on its own. The GulpDust PETG adapter fits the saw port on one end and your vac hose on the other.
Why should I measure the port myself?+
The 52 mm figure comes from one community adapter listing, not a caliper reading on our bench. The port is also stepped, so the number changes with where you measure. A quick caliper check makes sure you order a size that seals.
Do I need clamps to attach the adapter?+
No. The adapter is a friction fit. You press it into the port and it holds. The vac hose end works the same way.
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.
