75mm 88mm 90mm Plastic Dust Cover CNC Machining Parts CNC Router Spindle

Need a dust shoe that actually fits your spindle? This cover is moulded in three collar diameters — 75 mm, 88 mm and 90 mm — so one part family covers most small and mid-size woodworking routers. Measure the collar, not the motor body, before you order. Plastic body in red or green, split collar closed by one hand knob, clear skirt under the cutter, drilled base plate. Every unit is 100% inspected before it ships. Export by sea, air or express. Customised OEM service available.

Anyone machining MDF or plywood on a router meets the same three things. Chips fly up round the collet, so the nut packs tight and every tool change gets slower. Grit settles on the Z-axis rail and on the blocks behind it. And the extractor hose ends up cable-tied to the gantry or left on the table, because nothing holds its mouth at the cut. A cover in the wrong size only adds a fourth problem: it rattles, it lifts, or it fouls the collet.

This part is a moulded plastic cover that sits between the spindle and the work. The collar is made in three inner diameters — 75 mm, 88 mm and 90 mm — the sizes used on most small and mid-size woodworking routers. A split collar and one black hand knob clamp it round the spindle, so the cover drops on and lifts off in seconds, with no key needed.

The body is a single plastic moulding carrying two round ports: one clamps the spindle, the other takes the hose. Under the collar sits a clear skirt, so the cutter and the cut line stay visible while chips are pushed into the outlet. The flat base is drilled for fixing screws to hold it square to the Z axis. Colour is red or green, and every unit is 100% inspected before dispatch.

What separates this cover from a shop-made shroud or a one-size boot:

• Three collar sizes — 75 mm, 88 mm and 90 mm inner diameters, so three routers run one cover family instead of three fittings.
• Split collar, hand knob — one black thumb screw opens the ring, so the cover is released in about 5 seconds without touching the nut.
• Clear skirt — the ring below the collar is transparent, so the collet and the cut line stay in view on a full-depth pass.
• One moulded body — two round ports in one plastic part: one clamps the spindle, the other takes the hose, with no separate elbow to lose.
• Drilled base plate — the flat plate carries screw holes, so the cover stays square to the Z axis through the full stroke.
• Two colours — red and green on the same part, the quickest way to keep the three sizes apart on a tool rack.
• Outlet instead of spill — chips are pushed into the round outlet rather than thrown back onto the Z-axis rail and its linear blocks.
• 100% inspection — every finished cover is checked before packing, not one part out of a batch.
• Customised OEM — send a drawing or a sample and the cover is produced to that version instead of the stock one.

Dust control on a router usually comes down to two bad choices: a different boot for every spindle, or a shop-made shroud that survives one season. This cover sits between the two.

• Three sizes, one family. With collars at 75 mm, 88 mm and 90 mm, a shop running three routers stocks one cover family instead of three fittings, and colour keeps them sorted.
• You keep eyes on the cut. The clear skirt shows the collet and the cut line, so a rubbing cutter is caught before it burns an edge — one panel saved, not a sheet.
• Off and on in seconds. One hand knob frees the collar, so a tool change needs no Allen key and no re-hanging of the hose; it returns to the same collar position.
• Chips stop reaching the rails. The skirt drops below the collet, so debris goes into the outlet instead of onto the linear blocks, where grit shows up as play in the Z axis.
• A cheap part to replace. A cracked cover is plastic with its own part number, so it is swapped alone while the spindle, rails and extractor stay in service.
• Fits the machine you own. The plate is drilled and the collar clamps, so the spindle and the Z plate need no modification to run it.

Only if your spindle collar matches one of the three sizes: 75 mm, 88 mm or 90 mm. Measure the collar diameter, not the motor body, and compare it with those three numbers before you order.

Two ways at once. The split collar clamps round the spindle with a hand knob, and the flat base plate is drilled for fixing screws, so the cover is held on the collar and squared to the Z axis.

Yes. The ring below the collar is clear plastic, so the collet and the cut line stay visible and you can watch the chips leave through the outlet.

Through the round outlet port on the housing. Hose diameters differ between extractors, so measure your hose and compare it with the port before ordering — that is the one dimension we cannot fix for you.

Moulded plastic, in red or green, with a clear plastic skirt below the collar. There is no metal insert and no separate elbow in the body.

No. Red and green are the same cover in two colours, so the colour itself does not change the collar diameter — order by size first, colour second.

Yes. Customised OEM service is available: send the drawing or a sample and the cover is produced to that version instead of the stock sizes.

By sea, air or express, and every single cover is inspected before it is packed — 100%, not a sample from the batch.
