The Proform electric ring filer does the job very well and quickly. Compared to hand filing, an electric ring filer will save you hours of work if you plan on filing more than one set of rings. The dial indicator helps a lot when it comes to seeing how much you have ground off, but you will still need to check the ring in the cylinder a few times to get the measurement correct. You will have to use very light pressure and go slow when grinding or the dial indicator will jump all around, making it next to impossible to read. I recommend practicing on an old ring first to get the feel of how the filer works. Once you have it figured out, it's not difficult at all and you'll be less likely to mess up a ring. Overall this is a great tool for anyone who plans on building more than one engine. My only gripe is that Proform should have included a small sharpening stone for de-burring the ring edge like they recommend and saved me a trip to the store. ...read more

Proform 66765 ring filer is a must have tool

This electric ring filer is great. I bought it to replace my hand held ring filer. I work on big bore motors (4.13 and bigger)and it can be hard to keep equal pressure on both end at the same time. The Proform 66765 is excellent. The only short coming is it could use some more in-depth direction on it use. Thank goodness for You Tube.

Proform Electric Ring Grinder

Summit RacingSummit Racing Verified Purchase

PRO-66765
The Proform electric ring grinder/filer works pretty well. As mentioned already, the needle bounces around quite a bit which will take some time getting used to. But with a little experience a process can be developed for obtaining accurate results. The biggest issue I ran into with it though is the included grinding wheels. The ring ends are ground/filed using the face of the wheel. Given the wheel has an overly rough composite texture that can vary by 5-10 thousandths of an inch depending on where on the wheel you're measuring from, extra care needs to be taken to ensure accurate cuts are made. My advice is to mark the wheel using a black marker (or use some identifiable and repeatable feature on the wheel) to make before and after measurements from using the included dial gauge. Other than that, this item works well and beats doing it with a hand file or with a hand operated grinding wheel. ...read more

Good try

The instructions are terrible. Not even a picture of a ring installed. This could be improved alot if there was a stop for the ring and a rest for the back of the ring. I'm goint to rework mine and I think it will be great
