CNC Dust Shoe ABS Cover Cleaner for 3018 Series CNC Router/CNC Machines with a 42mm Diameter Motor, Hose Adapter Outer Diameter 38mm (1.5″), Transparent

It's a bit of effort to get a light hose connected so it's not in the way of the machine's normal operation, but it works as advertised. Be sure to get a chip separator to save your shop vac!! They're only a few bucks for a small one.

it works good

Well made and fits perfect on 300w spindle. (Genmitsu ProverXL 4060)

Just purchased the dust boot, first time using it, was working great for a while then the bristles got caught up in the bit. The dust boot was twisted and busted into pieces.UPDATE: Contacted SainSmart they immediately shipped a replacement. They also submitted the feedback to the product developers to request that they shorten the bristles to prevent issue on future products.They truly live up to their great support reputation! Trimmed the bristles down on the new one and its working great! The method i used was squeezing the bristles together and cut them short enough they could not easily reach the center where the bit spins.

Very happy with this well designed item. Fits perfectly and the magnet were a design coup as far as I'm concerned. The base screws to motor with two provided screws and allen wrench then the parts are held together with very strong magnets. Allow for quick , tool less removal to change and zero cutting tools.

The media could not be loaded. Keeping exposed ways and lead screws clean is critical for longevity of service. I recently purchased the Lunyee 3018 Pro Max and this shoe fits perfectly. I don't think I'll ever use the long bristle option but the short bristle option is perfect, my end mills sit about .2" below the bristles. I repurposed an old vacuum cleaner which delivers high pressure to the shoe and I have ZERO debris escape from it. I see videos here wherein the bristles are dragging the project piece which is not correct. My 30° V-bits are very short so I fabricated a plate to redirect the airflow so I use no bristles at all. I highly recommend this device, or whatever you can find to fit correctly, to keep debris contained.

I ordered this for my Genmitsu 3018-PRO with the upgraded 775M spindle. I noticed when I installed it that it blocks the lower ventilation holes on the motor but figured it was done that way for a reason. I ran a 30 minute cut. I have a 1/8 inch bit in there and had all kinds of issues with the bristles being too long and getting caught up in the cutter. I also noticed after the 30 minute cut the spindle makes some new really high pitch noises and it feels less smooth to rotate than before. I trimmed the bristles about 1/4 inch and ran another hour cut. The spindle did not seem to get any worse but I ordered a new one anyway. It sounds that bad. I'm going to drill some holes in the mounting plate that match up to the vent holes in the spindle motor. Looking at every other design I can find for a 775 size motor they all have vents in them for the motor to breathe. I emailed Sainsmart to tell them this is probably a problem but figured I would warn potential buyers anyway. Drill vent holes in the top piece. Other than those 2 issues it works fairly well. Keeps some of the dust off every flat surface within 20 feet of the machine. The bristles do clog up so keep that in mind for longer cycles. The magnetic attachment is great. Makes getting it off nice and easy but it is strong enough to not randomly fall off.

I love this dust buster. The only thing i hated is the head is so hard to get off when you need to setup for the next cut. I did a small mod splitting the front to give the bit space to pass.
