DustBubble is used with a hand frill to capture dust when drilling. 105 3 packs of Dust Bubbles. Regular Strength for wallpaper and painted walls Extra Strength for wood, plaster and untreated surfaces Industrial Strength for metal, and other industrial applications. DustBubbles are disposable dust collectors for DIY or industrial drills. They use a combination of adhesion to the wall and the action of the drill itself to catch virtually all the dust when you drill. They make drilling jobs easier - leaving both hands free while you drill and saves you the clean up afterwards. When you"ve finished drilling, you simply remove the DustBubble from the wall and discard it along with all the dust. Transparent, flexible and hands free: All DustBubbles are transparent so you can always see where you are drilling. The flexible material allows drilling at an angle or in restrictive spaces and DustBubbles stick to the wall surface so they are hands free for safer drilling. Tough and heat resistent: DIY DustBubbles are available for "Wallpaper and Painted Walls", "Kitchen and Bathroom Tiles" and "Wood (including MDF), Plaster (or Drywall) and Untreated Surfaces". For non-contamination issue maintenance work these offer a hugely cost effective protection against dust for general health and safety protection and reduce or eliminate clean up time.
