4 Pcs Dog Nail Grinder Replacement Heads Compatible with Casfuy, Professional Diamond Tips Drill Bit Pet Nail Spare Wheels Trimmers for Large Medium and Small Dogs

Easy to use, confort great quality, easy to clean

I am glad I got 60 grit grinders... I saw some video on groomers recommending 60 grit and this kit comes with two 60 grit and two 80 grit grinders. These fit my Lopsic grinders and I tried them on myself first and material are flying off faster. It took me much longer with the finer grinders that came with the lopsic grinders I got on Amazon. I'm very happy to get these...they work well.

It’s just a bit too long for the Casfuy grinder & hits the plastic top so had to return it…

We have a 20lb boston terrier with long quicks that we have historically been nervous to trim with typical bladed trimmers. These grinding bits are easy to install and seem to hold up fairly well against the nail material which gives me hope that they'll last a while. The vibration of the grinder is something that I hope my dog will get more comfortable with over time but overall she didn't fight or resist any more than normal although it takes a little longer to grind than it does to clip. I think this is a great idea and I hope that it works out long term.

There are 2 sizes: 60 (finer) and 80 (coarser.) They both fit in the grinder, until you put the plastic guard on. Then, the 80 spins but rubs against the guard, and the 60 does not spin at all… If you feel comfortable using without the guard, it will work fine and decent product for the price.

get the stock parts (original ones). nailguard is kind of important.....
