Casfuy Quiet Dog Nail Grinder, 6 speeds, 2 LED lights

The Casfuy dog nail grinder is a rechargeable grooming tool with six grinding speeds between 7,000 and 12,000 RPM. Two LED lights sit at the head, and the plastic body weighs 310 g (10.9 oz). It runs on a full charge for up to 4 hours and can be topped up from an AC adapter, a laptop or another power source.

Working through the ports and speeds

Start on a low setting and move up through the six speeds as needed; the range runs from 7,000 to 12,000 RPM. Three grinding ports are built into the head: the small port is meant for small pets, the medium port for medium-sized pets, and the unprotected grinding bit is the choice for the nails of larger dogs.

The grinder keeps the speed you were using when you shut it off with the power switch, so the next session begins on that setting.

Grinding bit, lights and dust sheath

The grinding bit is diamond-coated. A removable plastic sheath fits around it and holds the nail dust and debris that come off during grooming, and two built-in LED lights illuminate the nail while you work.

Which port suits your pet?

Check the size of your pet against the three ports before you start. The small port is designed for small pets and the medium port for medium-sized pets, so a small dog's nails go through the first opening and a mid-size dog's through the second. Larger dogs' nails are worked on the unprotected grinding bit, without a port around it.

Charging and running time

The grinder is rechargeable through an AC adapter, a laptop or another power source. A full charge gives up to 4 hours of use.
