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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    One of my favorite engine rebuild tools!
  

*by T***. on Reviewed in the United States on June 1, 2016*

This worked great for honing my 1972 Honda CB350F cylinders. Easy for first timers and cleans up all of the dark spots where the piston rings were stuck and sat for decades. I used a hand drill but you can also use a drill press if you have one. One great tip is to have the drill on at a low speed while you slide the hone tool in and out very swift motion. This will give it the perfect 45° cross hatching, otherwise you may get a more acute angle of cross hatching. Don't forget to use lubrication as well, I used Marvel Mystery oil which worked great.

    Easy to use and very effective
  

*by D***T on Reviewed in the United States on February 24, 2016*

Easiest hone in the world to use.  It should be within 1/8" of your bore size (LARGER, not smaller).  If you're used to flat stone hones, bear in mind that this hone must be TURNING when you insert it in the bore. Will deglaze any cylinder, even if it worn unevenly.  Even works on 2-cycle cylinders, but remember it must be within 1/8" of your bore size or the stones will catch on the ports, fracture, and otherwise misbehave.  A bonus for 2-cycle cylinders is it puts a nice little radius on the edge of the ports, eliminating the step of breaking the edge.

    Did exactly what I wanted
  

*by O***N on Reviewed in the United States on August 12, 2019*

I used this to clean up a hole used for an outboard motor travel pin that had seized. It cleaned out all the corrosion and gave me a nice clean hole in which to insert the bearing sleeve with around ten passes. Very important to get exactly the right size though. I chose one just a smidgen larger than the hole diameter.
