Works perfectly

Good grinder
Worked well on cast rings for an AMC 2.5l engine.

Works great for less money, but takes more work/time.
Used this to rebuild an LS engine. Worked great and got the job done, but took a lot of work and time. You will get faster with it the more you use it. Make sure you use the mount points to put it on a solid surface. Makes the work a lot easier. Don't be fooled, you'll have to put in some time and energy in using this, but the product does exactly what it promises for a lot less money than the automatic setups. The handle is a little awkward to use and can make your hand cramp up a bit because of its size, otherwise I'd give it 5 stars. Great product.

Solid, well built
Looked at tons of ring grinders, this one is totally solid, well built... rebuilding a '68 Chrysler 440, collecting necessary tools.

Perfect tool for the job
I had a jegs ring filer that needed a new wheel. As I searched for the replacement wheel I came across this one, which was about the same price as just a replacement wheel. So far I’ve used it to build 3 LS engines, and don’t see why it won’t do many more!

Piston Ring Filer
Good quality heavy duty product.
Reviewed in the United States on January 18, 2026 by Amazon Customer
Not a great filer, but does the job. For the price and frequency I use it I couldn't ask for much more.
I recently rebuilt my Porsche engine and needed a ring filer to get the ring gap correct. Even with this filer mounted to a solid surface it was a little clunky and difficult to use. The handle position makes it difficult to avoid hitting the ring while turning the handle. I wish it had a gear drive to offset the handle further away. Even better would be an adapter that would allow it to be connected to a Dremel or drill. Other than the awkwardness the filer did exactly what I needed. I was able to get clean filed edges and perfect gaps. Since it is something that I only use every few years I can't complain too much.
