    If you are only a tiny bit over the nominal size do not follow the instructions and go up one size. They are oversized to begin with (my 1 1/8 hone being a few thousandths shy of 1 1/4). I bought a 1 1/8 hone to remove the seam from 1 SCH40 pipe and open it up from 1.03 to 1.06 so that 3/4 pipe will telescope in structural applications. I also intended to use it to open up 25mm aluminum C-cell flashlight tubes to fit 26mm LiFePO4 cells (1.026). I am hoping that after breaking in the hone on the steel pipe I will be able to start it in the aluminum tube without damaging the end. I think in both cases I would have been better served in not following the instructions and buying the 1 hone instead.

    This is a great upgrade over regular 3 blade hones, especially for those that dont have much experience with regular hones. This hone is very easy to use and works very well, make sure you use a good lubricant while you hone, 10w30 oil is what I used. The one major downside to this and any other ball hone, over a regular hone, is that you can only use this hone for the specific size cylinders. Where 3 blade hones can be used for several different size cylinder bores. Other than that I would highly recommend this hone, it worked flawlessly for me.

    Honed a Golfcart cylinder in no time, removed fine scratches and ridge at top of cylinder in under 5 minutes. Pricey but cheaper than a machine shop and frankly equal results for all I needed.

    I have personally relied on products from this company for a very long time in a professional setting. As far as ball Hones go Flex-Hone is the best and has been. The quality is top notch and the number of sizes they make are unequalled by any other company

    Ive used these dingo-ball-hones in the past, and they work as well now as they ever did. This go-round was for a dirtbike cylinder, and the hone fit nicely, and cleaned up the bore to put a cross-hatch pattern into it. This ought to let the rings seat well when I finish the assembly. Watch some youtube videos if you need a tutorial, lots of them out there.

    Did 2 passes with the 240grit on a RM250 cylinder and it came out beautiful , real smooth

The Flex-Hone® tool was originally created by Brush Research Manufacturing to deglaze cylinder walls in automotive applications. Brush Research embraced the benefits of a plateau finish and pioneered the concept of plateau honing culminating in the introduction of the Flex-Hone tool in 1972. The Flex-Hone has gained many nicknames over the years and including ball hone, ball style hone, flexihone, dingleberry hone, bead brush, glaze breaker and glaze buster. Flexible honing with the Flex-Hone tool produces an oil holding cross hatch pattern and a true plateau finish free of cut, torn and folded metal. Any type or size of cylinder can benefit from the Flex-Hone®. These abrasive bead style brushes are produced in standard diameters from 4mm to 36 inches. Nine abrasive types are offered including silicon carbide, aluminum oxide, boron carbide and diamond allowing the tool to be tailored to finish any base material. A choice of 11 different grit selections are available for precise control of finish parameters. The elimination of peaks results in rapid ring seating, better oil control, reduced seepage in hydraulic and pneumatic applications and provides better seal performance and longer seal life. Successful applications include firearm chambers, shotgun barrels, musical instruments, combustion chambers, air compressors, pumps, valve bodies, valve guides, brake cylinders, wheel cylinders and the list goes on and on. Flex-Hone® tools are also very effective for deburring cross drilled holes, port radiusing and edge blending. Because of its unique construction, the Flex-Hone is self-centering, self-aligning, and self-compensating for wear so it does not require an elaborate set-up or special training. Deburring can be effectively automated and combined in the machining process to allow a complete cylinder finish in one operation or it can be employed as a secondary operation with equal results.
