52mm /65mm /80mm Spindle Brush Dust Shoe Sturdy Easy to Assemble CNC Engraving Machine Spindle Dust Shoe Cover for Engraving Machine, 65mm

Hats off to the designer and 3D printer of the connector. The downside is that the vacuum hose connector is small and the dimension of it is not listed. When attached to an 80mm spindle, producing loads of chips extraction is poor. The extraction port is adjacent to the spindle and not to the cutter. The 3D print has many loose print strands inside the suction port, the 3D printer used could not quite make the excessive unsupported print gap. Although 80mm diameter the magnets to secure the brush are at about 75mm this prevents the dust shoe from positioning where I would like to with longer CNC bits.

Good design, my standard size vacuum connection kit fits perfectly. The tolerance for the spindle is very good. The brush that came with it was too long, I could have cut it down but have had issues with other dust shoe after that. I found the opening was the same size as a yogurt pot so I have created my own brush. The magnetic detachable brush holder is useful.

Great product worth every penny highly recommended
