Dust Collection & Coolant
Dust shoes, cyclone separators, mist coolant, MQL, flood coolant, and the smoke / dross management tools for plasma and laser-adjacent CNC.
Routers make dust; mills make swarf and chips; plasma tables make smoke and dross; combo CNC/laser machines make all of it. Bad dust collection wrecks bearings and rails (see Maintenance) and is a real lung hazard. This page is mostly hardware — fans, hoses, pumps, and the dust shoes that hook everything together.
Dust shoes (router heads)
- ★ SuckIt Dust Boot (now part of OneFinity) — paid (~$200); brush-skirted dust shoe for Shapeoko / OneFinity / X-Carve / Sienci. The hobby standard.
- Carbide 3D Sweepy — paid (~$100); Carbide's official dust shoe for Shapeoko + Carbide compact router or Makita.
- Sienci Dust Shoe — vendor; ships with LongMills.
- OneFinity SuckIt Pro — vendor; their integrated post-acquisition.
- Kent CNC dust shoes — paid; well-regarded aftermarket. Mafell and Kress-specific options.
- DIY printable dust shoes — Thingiverse / Printables; hundreds of designs for every router/spindle combo.
Vacuums / dust extractors
- ★ Festool CT26 / CT36 — paid premium ($600–$1200); HEPA dust extractors with auto-start and bag systems. The "I'll never replace this" pick.
- ★ Fein Turbo II / III — paid (~$400); German workshop vac, beloved alternative to Festool.
- Bosch GAS / DeWalt DXV / Milwaukee 0960 — paid; tool-brand shop vacs; mid-tier.
- Rigid / Shop-Vac / RIDGID 6 gal — paid, cheap (<$200); the hobby workshop default. Loud.
- Oneida Dust Cobra / Dust Deputy — paid; cyclone-first systems sized for routers.
Cyclones / pre-separators
- ★ Oneida Dust Deputy DX — paid (~$140); the universal "drop in front of any vacuum" cyclone. Massively extends shop-vac filter life. Hobby essential.
- Big-shop cyclones: Oneida Super Dust Gorilla, Powermatic PM1900, Grizzly G0441 — paid; ducted systems for dedicated woodshops with multiple machines. Overkill for a Shapeoko corner.
- DIY Thien baffle / cyclone bucket — free DIY plans; works adequately if you can't justify Oneida.
- Anti-static hoses — important if you've had static shocks on shop vac hoses; Festool, Oneida, and Rockler all sell them.
Mist / flood coolant (mills, aluminum, steel)
- ★ Trico Fog Buster — paid (~$300); the gold-standard mist coolant nozzle for hobby mills. Compressed-air-driven, controllable mist, doesn't fog the room. Standard on Tormachs.
- Noga MiniCool / MagCool — paid; small-shop mist coolant arms; magnetic base, hand-pump or air. Less rigorous than Fog Buster but cheaper.
- MQL (Minimum Quantity Lubrication) — air + tiny droplet of vegetable-based oil. Burns clean, leaves chips dry. Good for production aluminum and not soaking the shop in coolant.
- Flood coolant systems — full enclosure, Tormach FlashCool / Bijur recirculating pump + sump; only realistic on enclosed mills (Tormach 770/1100, retrofit Bridgeports).
- Coolants: Trim MicroSol 585XT, Hangsterfer's S-500CF, Koolrite 2290 — paid; semi-synthetic mill coolants. WD-40 for one-off aluminum is the meme that actually works for light hobby cuts.
Through-spindle coolant / TSC
- Through-spindle coolant — high-end mills only; expensive sealed spindle, high-pressure pump (Chip Blaster, MP Systems). Mention only — outside hobby budget.
Plasma smoke / dross management
- ★ Water tables — water under the cut catches dross and dampens noise/smoke. Standard on industrial; Langmuir's MR-1 has a small water-table option.
- Downdraft tables — fan + duct under sacrificial slats pulls smoke down through the cut. Lincoln Flextec, Plymovent, Eurovac sell them; DIY versions are common (squirrel-cage blower + sheet-metal plenum).
- Overhead extraction — articulated arm + HEPA filter; Plymovent FlexMax, Lincoln Miniflex. For shops where downdraft isn't possible.
- Self-cleaning filter cartridges (Donaldson Torit, Camfil) — industrial.
Laser-adjacent (combo CNC/laser machines)
- See Laser Firmware & Controllers and laser ventilation guides for the diode/CO2 specifics.
- Activated-carbon filtration + outside venting is the standard recipe; combo CNC/laser owners need both dust collection (router mode) and air filtration (laser mode).
PCB-milling dust
- Bantam Tools vacuum nest + small shop vac — vendor recipe.
- Air assist — small compressed-air nozzle blowing chips off the cut; standard on Bantam, Carbide 3D Nomad workflows.
Pick this if…
- Shapeoko / OneFinity / Sienci, must do dust collection: SuckIt or Sweepy + Festool/Fein + Dust Deputy DX cyclone.
- Workshop on a budget: RIDGID shop vac + Oneida Dust Deputy + DIY printed dust shoe.
- Tormach / PM-class mill, aluminum: Fog Buster + a Trim semi-synthetic.
- Aluminum on a hobby router: MQL drip + air blast.
- Plasma table, garage shop: small downdraft or shop-built water table; ventilate the room.
- Production sign shop: ducted Oneida Super Dust Gorilla + dedicated machine drops.
