Cylinder

Nice tool 4 1/8 fits 06 5.7 hemi cylinder good fit used with regular engine oil for lubricant.

put a real good crosshatch on my 4.00 inch cylinder wall. could not be happier.

I bought this for my 1997 SeaDoo Speedster engine repair. I originally honed it with this but then found out I needed to get the cylinder bored over for other reasons. I took it into the machine shop and the machinist was in awe how amazing the cylinder looked he was wondering why I was even there. The cross hatch this tool leaves is second to none. This is a must have for anyone who regularly works on engines, but keep in mind these are fitted for specific size bores. If you just need one for a different size bore every time on new engines you work on, it might not be cost effective for you. For me, I would rather accumulate a whole set...so its all good for me.

I’ve used stone type hones for years, these are super simple, create a great cross hatch pattern and clean up easy. Only down side is the need for several sizes to cover what you can do with a stone type hone. For ease of use, I’d highly recommended.

Very easy to use with a good drill.

Works great. Produces a very good finish without cutting. Great tool if your cylinders are in good shape. I had to use a 3 stone hone to cut a little out of my cylinders and used this tool to get a good final finish after cutting. A+

Good Tool

It worked well for my SBC. I thought it should last longer than 1 V8 engine honing. Maybe its not supposed to, I dont know when I was done I noticed the dingle balls were smoothe.
