Special characteristics Sanding - What can you do with it? The sanding drum, which is attached to an extra strong steel mandrel, allows you to move sideways or orbitally to smooth surfaces, enlarge holes, or create irregular cavities. How to use the accessory? The drum is most effective when its edge is flush against the workpiece. To find the optimal speed, start slowly and gradually increase the speed to avoid excessive heat. Let the tool do the work at a lower speed and apply little to no pressure for maximum accessory life. Not recommended for use with metal or materials such as paint and other finishes, as the drum will clog quickly. What materials can it be used on? Ideal for a wide range of materials including Hard and soft wood Ceramic wall tiles Composite materials Plastic Fiberglass Stone Not recommended for use on metal Sanding Recommended speed Soft and hard wood 15,000-35,000 rpm Laminate/plastic 15,000 rpm Shell/stone 25,000-35,000 rpm Ceramic 15,000 rpm Hole Saw - What can you do with it? This accessory functions as both a sanding drum and a hole saw. The hole sawing function allows you to plunge cut into a wide range of materials. How to use the accessory? Begin drilling by holding your tool at a 45-degree angle. Continue cutting while moving the tool in a rotating motion. Let the tool gradually saw the hole. This way, very little heat builds up around the accessory, extending its lifespan. When drilling holes in ceramic wall tiles, start cutting the hole from the unglazed side of the tiles. To remove the stuck material from the hole saw, you can screw a screw into the material and pull it out, or you can gently tap the material with an awl until it breaks. What materials can it be used on? Ideal for soft wood and ceramic wall tiles. Not recommended for stone, porcelain, or hard floor tiles.
