Review: Worked for my needs. - I bought this hone to fix one of my Maglite flashlights that suffered the results of a leaky battery. I keep a three cell Maglite in each of my two vehicles and have added the LED bulb to them for increased illumination. I'm beginning to lose faith in many battery manufacturers because they all seem to leak any more. Any attempt to be compensated for a new flashlight due to their faulty product is usually met with a "too bad, we can replace the batteries but that's it." I caught this in time so that minimal damage was done but pitted the interior of the tube. I'd thought about using a hone before but never did so this time I decided it was time to do just that. I wiped out the inside to remove any residue then put the hone in my drill and worked it in and out until I felt good about the job. There is still some pitting but for the most part, the light has been restored to a usable condition. In other words, it works! I have run across other things that I would have liked having this hone to smooth out the interior of a tube before so now I have one. I have another flashlight that I want to use it on but I hope I don't have to use it on any more of my Maglites. I'm sure that this hone will work if I have to work over any cylinders on engines too but I hate working on that sort of thing so maybe not. Otherwise, I found this to be a very durable and useful tool.
Review: worked as expected. - works as expected

### ⭐⭐⭐⭐ Used for honing cylinders on 351w
*by P***R on May 3, 2015*

I used this for a Ford V8 engine. I plan on installing simple cast iron rings, which require a rougher grit honing. This tool is perfect for that. If you are planning to install moly rings, this is not the tool for you. You will need something finer grit. Word of caution... you have to be very careful not to stick it too far into the engine or it will come out into the block where the stones will hit the engine casting and chip or break. They are easy to chip or break this way. Just be sure to get a good feel for the depth, speed, etc. and it will work great. Anyhow, the tool is pretty sturdy. It works like it should. After a short test run I found the right settings to get a perfect 30 degree cross-hatch on my engine cylinder bores.
