Your cart is empty.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.

Working through my first engine rebuild and wanted to do it right.I would highly suggest reading through several sets of instructions and watching several videos on how to do this. Once you figure it out, it is super simple. Worked well and gave a good cross hatch finish on my cylinders. My only complaint would be one of the balls fell off during use. Other than that still worked fine.

I use these regularly to hone cylinders and they definitely have a great finish and an excellent price point. I buy these in this brand anytime I need a good hone brush.

I have to say I love these hones, I had to do an emergency ring replacement on a race engine before an event and there was no way to get the block to the machine shop. I ordered this hone and man it worked great. The finish it left was perfect. I checked cylinder leakage after install but before running and every cylinder was below 10% I had to fire the engine up throw the car in the trailer and make a 1000mile drive to the track. We'll the car ran perfect used no oil needles to say I'm very happy with this hone. Will buy more of these for tricky situations!!!

Used this to hone four cylinders in a two-stroke outboard motor. Didn’t take long for the honing balls to start breaking off as they passed by the cylinder wall ports. Luckily the ball stems are plastic and didn’t damage the cylinder walls. Eventually got the job done, though, producing a nice crosshatch surface finish.

I have a 2005 Honda CRV that was burning one quart of oil per tank of gas. YES you did read that correctly. Car was abused before I got it, but now I have to fix it. Pulled the engine apart and found scoring on the #4 cylinder wall and a damaged piston. Replaced all 4 pistons, rings, and rod bearings. Took this hone to all the cylinder walls with a little "extra" in #4. All the bores came out factory perfect, except #4 which I would give a 8 out of 10. You could still see some vertical lines but it was 95% better than before. Hondas stance is do not hone, just install rings, and if you can catch a scratch with your fingernail, the block needs replacement. Well I wasn't replacing my block, so this was the next best thing. Put it all back together and the engine runs perfect. Car does not burn a drop of oil and the oil is still golden. It would be black from blowby within 500 miles before. Very pleased! and highly recommended.
