With the Makita 191g69-8 drywall bit, you make fast and accurate cutouts in plasterboard and drywall partitions. The 3.18 mm diameter delivers clean, detailed openings for electrical boxes, switches, and conduits without tearing or crumbling the edges. Manufactured from high-speed steel (HSS), it cuts smoothly and withstands demanding use. Its 33 mm cutting length allows you to route completely through standard panel thicknesses with ease. Thanks to the plunge tip, you can penetrate directly into the board to start cutting immediately without pre-drilling.
