100mm Dust Collector Dust Cover With Brush For CNC Spindle Motor Milling Machine

Want the chips off your rails and into the vacuum instead of across the table? This 100 mm dust shoe wraps the spindle of a CNC router, engraving or milling machine with a nylon brush skirt, and a round outlet port pulls the dust away at the cut. Painted thick steel plate body, push-pull sliding collar for bit changes, brush strip that lifts off on its own, and collar sizes from 67 mm to 125 mm. One spare part, replaced in minutes, no machine rebuild.

Three things go wrong on a floor that cuts MDF, oak or plywood all day: chips pile up on the rails and linear guides, the operator stops every few minutes to blow the table down, and the nozzle that came with the machine sits too far from the cutter to catch anything. This 100 mm dust shoe is built to close all three gaps where the material is actually cut.

It is a push-pull dust shoe for a CNC spindle motor. The 100 mm collar wraps the spindle body, the flat white body carries a round vacuum outlet, and a nylon brush skirt hangs to the work surface, so chips leave through the port instead of flying.

The upper body is thick steel plate painted white, with a black hand knob at the front. The brush strip is a separate part: lift it off, drop a new one on, and the body stays on the spindle. A sliding gate opens the collar, so a cutter or collet is changed with the shoe still mounted.

The same shoe comes in 67, 70, 80, 90, 105 and 125 mm collar sizes besides this 100 mm version, so one machine family needs one part number per spindle. It is a woodworking machinery spare part made in China, listed for CNC spindle motor milling machines, routers and engraving machines.

What each part of the shoe does, with the numbers that matter when you order:

• 100 mm collar — the bore size of this SKU; the same body is also produced in 67, 70, 80, 90, 105 and 125 mm for other spindle motors.
• Push-pull sliding gate — the front of the collar slides open, so a cutter or collet is changed with the shoe still bolted to the spindle.
• Nylon brush skirt — dense yellow nylon bristles hang around the opening and flex over the work surface, closing the gap the vacuum would otherwise lose.
• Detachable brush strip — the bristles sit on one separate strip; lift it off and the white body stays on the machine.
• Thick steel plate body — painted white, iron plus nylon construction, with the stiffness a part bolted next to a spinning spindle needs.
• Round vacuum outlet — a single circular port on the top face carries the dust out of the shoe instead of letting it settle.
• Single hand knob — one black knob at the front clamps the collar, so fitting and removal take a hand, not a tool set.
• Flat, shallow body — the housing stays low around the spindle instead of hanging under the gantry.
• Spare-part fit — sold as a woodworking machinery spare part for CNC spindle motor milling machines, routers and engraving machines.

Most shops choose between running the spindle bare and buying a shoe that never quite fits. Neither is a good trade:

• Dust lands in the hose, not on the rails. A brush skirt around the cutter plus a round outlet port means the chip path ends at the vacuum, which is the part that wears linear guides and ball screws.
• Bit changes stay a one-minute job. The collar opens with a push-pull slide, so an operator does not unbolt the whole shoe to swap a cutter or drop a collet.
• Brush wear is a strip, not a shoe. Because the bristles are one detachable strip, a worn skirt is replaced as a spare part while the steel body keeps its place.
• One part number per spindle, not per machine. With 67 mm to 125 mm collars in the same design, a shop running several spindle motors keeps one familiar shoe.
• Fits the machines already on the floor. It is listed for CNC spindle motor milling machines, routers and woodworking engraving machines, so it goes on an existing head.
• Steel where it is loaded, nylon where it touches. The thick steel plate body holds the shape, the nylon brush takes the abrasion, so the cheap part wears first.

Only if the spindle body it wraps measures about 100 mm across. The number in the SKU is the collar bore, so measure the spindle first; if it is not 100 mm, the same shoe comes in 67, 70, 80, 90, 105 and 125 mm.

Yes. The collar is a push-pull sliding gate: slide the front section open, change the cutter or collet, close it again, and the body never leaves the spindle.

No. The brush is a separate strip. Lift the worn strip off the white body and fit a new one; the steel plate housing stays where it is.

No. One shoe covers any cutter that passes through the collar opening. The sliding gate gives access to the collet for the bit change, so the same part serves the whole cutter set.

Thick steel plate for the upper body, nylon for the brush. The steel is painted white, the bristles are yellow, and the two materials are listed together as iron plus nylon.

Yes. It is listed for CNC spindle motor milling machines and its scope of use covers woodworking engraving machines and CNC routers with a matching spindle diameter.

With one hand knob. The collar slides over the spindle body and a single black knob at the front of the body clamps it, so fitting needs no tool set.

Six: 67, 70, 80, 90, 105 and 125 mm. They are the same design in the same white steel and nylon brush, so a shop with mixed spindles orders one collar size per head.
