What can you do with it? Combined with the Dremel 7020 pet nail grooming tool these sanding discs can be used for safe and stress-free nail filing of your pet’s nails. The discs have a grit of 60, making them the perfect accessory for gradually sanding away the nail. How to use it? The accessories can be attached to the EZ SpeedClic mandrel up to 6 times faster, which allows you to change accessories as quickly as pull – twist – release. By gradually sanding away the nail bit-by-bit, you are less likely to cut quickly, which causes the nail to bleed. Materials to use Use it on your pet’s nails.
