    This is an easy way to remove a small amount of metal from cylinders. It creates a smooth surface. I would recommend this item to others who wish to enlarge the inside of a cylinder.

    Used this for refinishing a plow piston cylinder. A lot of people complaining about the price but this is much cheaper than any other available option, whether sending out to get machined or buying and actual hone setup for at home.

    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 was putting in new rings, but had a glaze on the cylinder bore. this quickly removed the glaze and will allow the new rings to seat properly.

    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.

    Tried using a hone on a motorcycle bore but it was going to be slow going. Used the Flexhone and it did a beautiful job of crosshatching the glaze. Had to be careful as it was a bit aggressive but did the job so quickly it was a real pleasure to use.

    Used this for my nikasil cylinder on my Crf250r. Only did 6 passes to get the glaze off the cylinder and it worked perfectly.

    I use it for cleaning up a ported cylinder

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.
