This dust shoe is made of high-quality transparent ABS . The transparent design helps you keep an eye on your operations. Equipped with a 40mm long nylon brush to maximize vacuum suction and help act as a dust sweep with high dust removal efficiency. Keep your machine and work area clean while cutting, drilling, and carving.

Two-Piece Magnetic Design: Durable, light and flexible, convenient for daily use and maintenance. Easy to assemble and install. Only take 3 steps to finish the installation.

The split design makes it much easier to replace bits. You only need to pop off the bottom cover when replacing your bits, no tools required , and avoid other complicated procedures.

The planting brush is much tidy and firmer than other glued ones. You could just replace the whole bottom cover when the brush is worn. Don’t need to spend much time removing and adding a new brush (If the brush is too long for your bits, we suggest that you could trim it off from the bottom according to the bits length or order a Replacement Base Bottom Cover with 20mm long nylon brush).
