With the Makita 199142-6 dust extraction attachment set, you drill and chisel cleanly without spreading hazardous dust across the workspace.

Built to accommodate drilling diameters up to 40 mm, depths up to 380 mm, drill bits from 305 to 570 mm, and chisels from 280 to 600 mm, it simplifies heavy-duty wall and overhead jobs while saving valuable clean-up time.
