Love these I purchased 2 sets. The cheap ones I bought on Amazon didn’t fit well and squeaked terribly. My e-filed are my most expensive tools and I take care of them. You need these no matter what file you are using. I’m using in my KB and YN e-files and th we t are perfect-even though my YN file has been resting at home lately!
I love these ! I had ordered some cheap rubber ones from Amazon but the squeaking made me nuts. These work with both my KB file and YN Desk file (it’s been lonely since I got the KB e-file) BUT we have to protect our tools. Can you imagine the dust that gets in without the cap? I ordered 2 bags and plan to replace at least once a year. Spend the 9$ - it’s way cheaper than sending your hand piece in to be serviced or replaced.
Brilliant product! I have drill bits that don't have dust caps so it is wonderfull that I can order them when I need them 🖤
These are a great addition to my bits and put my mind at rest as to what is going into my file. Will possibly need some more for some of my other bits.
I love these little caps
