Rank #5 in Best Dog Nail Grinder 2026: 10 Ranked, Four Share One RPM Band
Casfuy N60 6-Speed Dog Nail Grinder, 7,000–12,000 RPM
Price and rating as shown on Amazon when we collected them. Both change.
This is the Casfuy 6-Speed Dog Nail Grinder, fifth in our guide to dog nail grinders. At £21.24 it is the cheapest of the four Casfuy listings in that guide, and on paper it looks like the dearer ones: the same 7,000–12,000 RPM band, the same six controlled speeds, the same claim to suit small, medium and large dogs. The £24.99 and £23.99 Casfuy models behind that same RPM figure also claim 7 hours of use from a 2,000 mAh cell. This one does not. Its own bullet says it lasts 2 hours after a 3-hour charge — a fraction of the runtime those two claim, for a saving of £3.75 against the £24.99 model.
There is a second inconsistency inside the same listing. The bullet headed "Rechargeable & Portable" describes a cordless grinder charged over USB, while the specification table underneath says "Batteries: 4 AAA batteries required" and "Batteries Included: No". Both cannot describe the same device as it ships. Every figure on this page comes from the Amazon listing for this model, not from any testing we carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I don't normally do reviews but this is so good I felt I had to. This product is amazing. My dogs hate having their nails cut. It takes about 2 hours. They have arthritis so can not do a lot of pavement walking to wear the nails down. Whilst my dogs were a little nervous they soon got used to it and it does a brilliant quick job. Saving me a lot of money to have someone come and cut their nails aswell.”
