It works as a dust collector for drill use with compatible 16 cm/6.2 in hole saws.Suitable for home repairs, wall openings, fittings, and installation tasks using an electric drill or hammer drill. The flexible bowl surrounds the cutting area to help contain loose chips and drilling dust.Compared with drilling without a cover, this attachment provides a neater work area and reduces cleanup. It can also serve as a rubber drill dust cover or drill machine dust cap for compatible setups.Press the silicone bowl firmly against the surface before drilling and keep the cutting tool aligned. Empty collected debris after use, then wipe and dry the attachment before storage. Support is available for product-use questions.
