The Grout Removal Attachment comes with two different adapters so it can fit on several Dremel tools. The 568 Grout Removal Attachment can fit Dremels with model numbers 4000, 400, 398, 395, 300, 285, 275, 200, 100, 8200 and 800. According to Dremel, the tool is also compatible with the Dremel Advantage High Speed rotary saw or any other Dremel rotary saws that have standard-size collars.
The Dremel 568 Grout Removal Attachment has several features that help you control where the tool’s bit sits, avoiding damaging the tiles. The attachment has a cutout or window that allows you to see the bit’s placement while you are working to remove the grout. Guides sit on either side of the bit, helping protect against the bit accidentally contacting the tiles as you work. Since not all grout lines are the same width, the attachment allows you to adjust its cutting angle up to 30 degrees. You can also control how deep the bit penetrates through the grout, adjusting the bit to cut up to 3/8 inch below the tiles, avoiding damaging the tile’s substrate, or the material under the tile.
You must follow the directions on the use of Dremel's Grout Removal Attachment to avoid damaging it or the tiles. If the attachment’s bit does not fit between the tiles without contacting the tiles, remove it using the wrench that came with the attachment to loosen the bit in its slot. Insert a smaller bit into the attachment and tighten the bit in its slot with the wrench before turning the tool on. If you are working on removing grout from wall tiles, you must move the tool from top to bottom. When you are removing grout from side to side, you must draw the tool toward you, instead of pushing it away, to maintain maximum control.
While operating the Dremel 568 Grout Removal Attachment, you must keep in mind some safety considerations specific to the tool. To protect yourself from electrical wiring that may be behind the tile you are removing, always keep your hands on the tool's insulated handles while cutting into grout. Turning on the tool while the bit is against the grout, or holding the tool with one hand while it is running, can cause you to lose control of the tool, damaging the tile or injuring yourself. Using dull bits in the tool can cause you to push too hard on the tool, leading to bit damage. Damaged bits can break, possibly leading to personal injury.
