QWORK Dog Nail Grinder Replacement Head, 10 PackPet Nail Grinder Diamond Tip Replacement, Professional Spare Grinding Head for Electric Pet Paw Trimmer Nail Grinder, Dog Claw Smoothing Grinder Bits

The heads are very tough and last.Very happy I found them.Works with the PETPROVED nail grinder.

Bought this as replacement heads for my Casfuy nail grinder that was losing its efficiency. As others have mentioned, these heads are a bit bigger than standard and will rub against the cover for the Casfuy. If you have a large dog with thick nails, this likely won't be an issue as you won't be using the cover anyways. Using one of the brand new heads I was able to grind all of my dog's nails down to the quick in a matter of minutes and shaping the nail was also a breeze. At this cost, QWORK is a no-brainer if you've got a dog with super thick nails. Highly recommend.

These replacement heads fit my nail grinder perfectly, which was a relief. However, they don't seem to match the quality of the original ones that came with the grinder. They work fine, but I've noticed they wear down a bit quicker than I expected. For the price, they're still a decent option, especially if you need a backup set for regular trims. Just keep in mind they might not last as long as the originals. Overall, they get the job done, and having 10 in a pack is convenient.

These are way better than typical Dremel bits and a lot easier to file down my dog's nails. Not only that they last forever and you hardly ever have to replace them

Fits my dog nail Dremel well.Has lasted much longer and does better than original that came with tool.

I love them they are verygood quality!!!!

I have a casfuy grinder and it doesnt work with the guard on but does without it. It did get caught in my dogs hair one time and ripped some of his hair out.

These arrived as described. They really don't work that great on my dogs' nails. I have since switched to a tool with a sander.

Purchased for my dog pet paws device. Fit perfect and works well. Happy with purchase

They don't last very long. But they are 10 for the price of one. They fit. They work.

I recently purchased this dog nail grinder bit replacements and have mixed feelings about it. On the positive side, it's easy to use and fits perfectly with my existing grinder. The price was also reasonable.However, I've noticed that the grinding surface wears down relatively quickly, requiring frequent replacements.Overall, it gets the job done, but I'd love to see improvements.
