Product Features

  • Self-centering, self-aligning, and self-compensating for tool wear, to reduce set-up time and costs and the need for special operator training
  • A soft cutting action to create a plateau finish through a low-temperature abrading process that exposes undisturbed base metal, to help produce a long-wearing surface
  • Grit size ranges from 120 to 320; higher grit numbers are finer, to help create a smooth surface finish
  • Order by actual bore size as the tool is produced oversized
  • Silicon carbide is more aggressive and cuts faster than aluminum oxide

The hone was well packaged and arrived in good order. We put it to use right away. We are working on an 1976 Fiat 124 Spyder thats been parked since 1996. Rings rusted onto cynilder walls. This hone alowed us to clean up the rusted areas in just a few minutes. We now need to assess wheather to re- ring and reassemble or to bore.

This is a great ball hone for my Evo engine rebuild. All that was needed was some hone oil and this thing. Made terrific cross hatch pattern. Highly recommended!

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.

don't have a lot of experience with honing, so nothing really to compare it to. there is a technique to get the right cross hatch pattern. just used it to clean up the cylinder wall when installing new rings. have to move it quickly depending on the drill speed, but it left a really nice pattern and cleaned it up really nice. its quite aggresive so it only takes a few seconds. be careful

I was in a hurry to rebuild my Honda K24 bottom end so i ordered the Flex-Hone to get the cylinder bores ready. It arrived extremely fast and the end product looked better than what i have received from most machine shops. It's also a lot easier to use than the 3 stone honing tools and delivers a better finish on the bore.

Brush Research Flex-Hone: if you have not used one of these before you may be surprised at how well they work, just as advertised! They last a long time, and leave the proper finish to break in new rings in about a minute. What more do you want?

I've been using flex-hones on my engine builds for several decades and they always give me the finish I want. They are inexpensive so it's not a big deal that I need 4-5 to ocver all the different sizes I need. A great product!

Worked exactly as described, quick and clean. Only con: must buy one for each size cylinder you are doing (this was a 3 1/2").
