The Casfuy 6-Speed Dog Nail Grinder sits at number four in our guide to dog nail grinders. It is listed at £23.99, it holds 4.4 out of 5 from 834 ratings, and Casfuy quotes 7,000–12,000 RPM across six speeds from a 4.8V copper core motor. What separates this listing from the other Casfuy entries in the guide is the runtime attached to that same speed band: 7 hours from a 2,000 mAh lithium-ion cell, which the listing says is enough to trim 30-50 dogs on one charge.

The listing's own numbers do not all sit comfortably together. It gives the item weight as 322 g and the package weight as 0.32 kg — that is 320 g for the parcel, so the grinder is listed as heavier than the box it arrives in. The model number here is N70, while two other Casfuy listings in this guide share the model number LGL007. Everything on this page comes from the Amazon listing and not from any testing we have carried out.

Six, adjustable from 7,000 to 12,000 RPM. The listing suggests higher speeds for quick shaping and lower speeds for precise work near the quick.
