The Andis Cordless Nail Grinder 66815 is a rechargeable tool for routine nail shaping and smoothing at home. Its DNG-1 design uses a rotary motor with adjustable speed, allowing you to change the setting as you work on individual nails. Cordless operation leaves the handpiece free of a trailing power lead during grooming, making it easier to reposition your hand around the paw.

Separate plus and minus buttons control the speed, and the grinder starts at its middle setting. The lithium-ion battery is rechargeable through the supplied adapter. This model operates on battery power only and will not run while it is charging, so charge it before beginning a session. Indicator lights show the battery's remaining charge and charging status.

The grinder uses replaceable sanding attachments held in a collet. Switch the tool off before changing an attachment, and check that the sanding band is secure before starting. The removable attachment system allows worn abrasive components to be replaced as part of normal upkeep.

For practical use, support the toe, keep hair clear and remove nail material gradually while checking for the quick. Use light pressure and short, moving passes. After grooming, switch off and brush away nail dust, then wipe the body with a soft cloth. The handpiece measures 8.30 inches long and weighs 12 ounces. Its charging supply is rated for 100–240 V, 50/60 Hz.
