There is increased awareness of the importance of dust extraction on job sites, and Makita is meeting demand with a growing range of dust extraction solutions. The Dust Extracting Attachment (197172-1) is ideal for use with demolition hammer (1-1/8” Hex Shank). It attaches directly onto the bit shaft, from 1” to 4” away from the surface, and the hose is kept out of the way with the convenient hose holders. When used with a job site vacuum (sold separately), the attachment is engineered for maximum dust extraction.
