The Hand Sanding Companion
The 3M™ Hookit™ Dust Free Sanding Block is the perfect companion when you have a high-dust project in a tight spot. This sanding block fits comfortably in the hand to help reduce instances of hand fatigue while delivering consistent application of pressure for more uniform results. A sanding block also lets you apply more pressure than you could simply with your hand, a benefit that will help improve how quickly you can complete your project.
The Hookit™ Advantage
This sanding block uses the 3M™ Hookit™ attachment system for quick replacement of sandpaper sheets. Simply press on the abrasive sheet to get a secure grip, and then peel it away for easy removal. Hookit™ is the perfect time-saving answer when you’re switching between abrasive grits frequently, or if you are working in a dusty environment. Best of all, you can reuse abrasives that still have a useful service life. Simply save the partially used sheet until your next project. Hookit™ ensures that you will get the same secure hold every time, which can help you save time and money in the long run.
Keep Your Hands Dust Free
When connected with a vacuum system and used with dust-free or clean sand pads and abrasives, the 3M™ Hookit™ Dust Free Sanding Block can pull dust from the workpiece for improved sanding efficiency and a cleaner working environment. It has a threaded attachment feature that enables easy yet secure attachment and detachment of an external threaded vacuum hose (sold separately) to effectively reduce dust from the workpiece. This makes hand sanding in tight spaces much easier, and helps you get a more consistent finish.
