70mm 80mm CNC Router Dust Hood CNC Dust Cover For Engraving Milling Machine

Need to pull wood dust off the spindle instead of sweeping it off the bed? This hood clamps around the spindle body in one of five bores — 70, 75, 80, 88 or 90 mm — and passes the chips out through a 100 mm vacuum port on a body 260 mm long. A sealant strip closes the gap to the workpiece, one screw closes the split collar, and the seals are supplied free with the hood. Green engineering nylon, made in China.

A router cutting MDF without extraction leaves three things behind: a bed buried in chips after every pass, a dust shoe bought for one spindle size that fits nothing else, and a hood that twists mid-cut because the collar never tightened onto the spindle. All three come back to two joints: how the hood grips the spindle, and how it meets the hose.

The 70/75/80/88/90 mm CNC router dust hood is a one-piece cover that clamps around the spindle and carries chips out through a 100 mm vacuum port. Body length is 260 mm from the collar to the end of the suction tube, which sets the port clear of the gantry and close to the hose. The lower ring carries a sealant strip, so air is pulled through the hood instead of around it.

Five bores cover the spindles used on woodworking router tables: 70 mm, 75 mm, 80 mm, 88 mm and 90 mm. The front is a semi-circle rather than a thin lip, so there is no sharp corner at hand height; the port and the rubber strip are clamp-held.

The body is moulded from engineering nylon plastic in green, light enough to hang on the spindle without loading the Z axis. It is a spare part for woodworking engraving and milling machines, made in China, with the seal supplied rather than sold separately.

A dust hood is decided by three things: how it grips, how it seals, and how big the port is.

• Five spindle bores — 70, 75, 80, 88 and 90 mm collars, so one hood line covers the spindles found on most woodworking router tables.
• 100 mm vacuum port — the suction tube takes the 100 mm hose used by workshop extractors, with no reducer at that end.
• 260 mm body length — the port sits 260 mm from the spindle collar, which keeps it clear of the Z axis and the gantry rails.
• Sealant strip supplied — a flexible strip closes the gap between hood and workpiece, and the seals are provided free with every unit.
• Single-screw split collar — one knurled screw opens the collar, the hood slides onto the spindle, and the same screw closes it again.
• Clamped port and strip — the port and the rubber strip are fixed by clamps, not friction slots, so neither works itself free.
• Rounded front profile — the front edge is a semi-circle with no thin lip, keeping hands clear during fitting.
• Nothing to wear out — one nylon body, one strip and one screw: no bearings, springs or moving parts.

A shop with several spindles has two options: a hood per machine, or a hood per spindle size. The second is cheaper, and the fit is better because nothing is being stretched to cover a size it was not made for.

• Dust leaves at the cutter. Chips are caught at the 70–90 mm collar and carried out through the 100 mm port, so the bed and the floor stop collecting what the cutter throws.
• One hood line covers a spindle fleet. Order 70, 75, 80, 88 and 90 mm together and every spindle on the floor has a hood without a new part number being created.
• Tool changes stay fast. The collar opens on one screw, so changing a bit does not become a hood change, and the hood goes back in the same position.
• The seal does the extracting. A strip held against the work surface keeps the 100 mm port pulling air across the cutter instead of pulling it from the open room.
• Nothing on it will rust or dent. Moulded nylon takes the knocks a hood gets at the edge of a job, and the weight stays low enough not to hang on the Z axis.
• Spare-part simple. There is nothing to service: if a strip is worn or a body is cracked, the part is replaced rather than repaired.

Measure the spindle body, not the collet nut. The hood is made with 70, 75, 80, 88 and 90 mm bores, and the bore matches the outside diameter of the cylindrical spindle housing where the collar sits.

A 100 mm hose. That port diameter is the same on every size in this range, so an extractor with a 100 mm inlet connects straight on; a smaller hose needs a reducer.

Yes. The strip is supplied with the hood and the seals are provided free, so there is no separate seal part to order as well.

No. The split collar is closed by a knurled screw, so the hood goes on, comes off for a bit change and goes back on by hand.

Yes. The collar clamps onto the 70–90 mm spindle body, and the suction port and rubber strip are each held by clamps, so there is nothing to work loose in a cut.

Yes. The hood is specified for CNC router engraving and milling machines; the 260 mm body and 100 mm port are the same across the whole size range.

Yes. 70, 75, 80, 88 and 90 mm are all listed as available, so a mixed order covers a mixed spindle fleet. Price is quoted per order.
