85mm Spindle Dust Shoe Boot Collector For CNC Router Engraving Machine

A dust shoe boot for CNC router and engraving machines, with a push-pull sliding door and a flexible nylon brush. The body is iron, painted white, and the brush ring is nylon. The size is 85mm, and the same shoe is made in 67, 70, 80, 90, 100, 105 and 125mm. Before ordering, measure the spindle or collet diameter on your machine and match it to the 85mm figure. The detachable design lets you lift the cover for bit changes and cleaning without pulling the spindle.

Chips and fine dust thrown by the cutter land on the rails, in the T-slots and in the air the operator breathes. A shoe that sits too high misses the stream; one that drags on the work marks it.

This is a CNC dust cover, also called a dust shoe boot, in white. The upper body is iron; the brush is nylon. It fits CNC router and engraving machines with an 85mm spindle. The same shoe comes in 67, 70, 80, 90, 100, 105 and 125mm, so confirm your spindle diameter against the 85mm size before you order.

The body is a push-pull type with a sliding door, and the brush ring is detachable. You slide the door to reach the collet for a bit change, then close it to run. The flexible nylon brush follows the work surface and keeps the extraction path closed around the cutter.

Shoes ship as CNC spare parts from China. Packaging and customisation are not stated, so ask before assuming. Send your spindle diameter, the machine model, and a photo of the current mount or spindle nose with your enquiry. Say whether you need the 85mm size or one of the other diameters, and ask what is in the box.

What the specification fixes, and what it leaves to the machine:

• Sliding door access — A push-pull sliding door in the iron body lets you reach the collet for bit changes without removing the whole shoe.
• Flexible brush ring — The nylon brush bends against the work surface and closes the gap around the cutter so chips stay in the airflow.
• Detachable for cleaning — The brush ring comes off the body, so you can clear packed dust and chips without tools or a full strip-down.
• 85mm spindle fit — The 85mm size fits CNC router and engraving machine spindles of that diameter; measure yours before ordering.
• Iron upper body — The upper body is iron plate, painted white, which holds its shape when the brush presses against the table.
• White painted finish — The white paint makes dust build-up visible, so you can see when the shoe needs cleaning.
• Size range check — The same shoe is made in 67, 70, 80, 90, 100, 105 and 125mm; match your spindle to the 85mm figure.
• Woodworking use — Built for woodworking engraving machines, where the cutter throws chips and fine dust at the rails.
• Push-pull operation — The push-pull action keeps the door where you set it, so it does not drift open while the spindle runs.

What changes on the shop floor when the right part goes back in:

• Keeps chips off the rails. Debris that reaches the linear rails and T-slots turns into wear and lost accuracy. The brush ring and extraction port catch it at the cutter.
• Bit changes without removing the shoe. The sliding door opens over the collet so you can change a bit and close it again. That saves a removal and remount each time.
• Brush ring comes off for cleaning. Packed dust in the nylon brush reduces airflow. A detachable ring lets you pull it, clean it and refit it during a short stop.
• One design across seven sizes. The shoe is made in 67, 70, 80, 90, 100, 105 and 125mm. That covers several spindles on the same shop floor with one familiar mounting pattern.
• Iron body holds its shape. The iron upper body does not flex like thin sheet when the brush presses on the work, so the gap around the cutter stays even.
• White paint shows the dust load. A white body makes chip build-up easy to see. You clean on condition rather than on a fixed schedule.
• Breathes easier at the table. Capturing fine dust at the cutter keeps it out of the operator's air. The nylon brush and extraction port do that at the source.

Measure your spindle diameter first. The 85mm size fits an 85mm spindle; the same shoe is also made in 67, 70, 80, 90, 100, 105 and 125mm, so match the number to your machine.

The upper body is iron, painted white, and the brush is nylon. Those are the two materials in the shoe.

Yes. The body is a push-pull type with a sliding door. Slide it open to reach the collet, then close it before cutting.

The brush ring is detachable. Pull it off the body, clear the packed dust and chips, and refit it.

It is made for CNC router and engraving machines used on wood. The brush follows the work surface and keeps the extraction path closed.

The shoe comes in 67, 70, 80, 90, 100, 105 and 125mm. This page is the 85mm size.

Send your spindle diameter, your machine model, and a photo of the spindle nose or current mount. Say which size you need and ask what is in the box.

That is not stated, so ask. Send the question with your size and machine details and wait for the answer before you order.
