Brush Research FLEX-HONE Cylinder Hone, BC Series, Silicon Carbide Abrasive, 3 (76 mm) Diameter, 240 Grit Size

Perfect product, great description about getting the right size for my cylinder. Thanks

Worked great

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.

Purchased 76mm for honing an old ATV cylinder. Some WD40 and several passes later the bore is cleaned up and has a nice surface for the new piston rings to seal in. Cleanup is easy with carb or brake cleaner. Make sure to get the right size hone for your bore!

This was exactly what I needed at a VERY affordable price. Came in 3 days!! Wicked F A S T shipping!!

Got it fast and item as described. Love it.

So I have this 1982 Honda Magna I recently acquired which needs some love to get back on the road. Apparently the previous owner dropped the bike while loading it on a trailer, decided not to fix it and let it sit for a few years. The sight glass was busted on the clutch master cylinder so the fluids drained out of the main chamber and after a few years of sitting, the rest of the fluid turned into some kind of green alien substance... After stripping some screws trying to get the thing took apart, I discovered the piston was quite stuck in the chamber - which required me to drill through the top of the piston, insert a metal screw and pry the b***h out with a crowbar. What I found in the chamber was nothing short of horrific - a nice thick black coating of whatever the brake fluid turned into after all these years. It looked like carbon, and it was impossible to get scrubbed out with brass bore cleaners or soaked out with anything I had available (which is a lot of stuff). I searched around for potential replacements on eBay, but there was nothing that looked like it would be a sure buy that would work - especially for the money these people were asking. So, I have to make this work... Eventually I gave up on the fruitless manual labor and tried to find another solution. Stumbled across honing engine cylinder and started looking for really small honing tools (5/8 or 16 mm). Found this, got it today, attached it to my drill, doused the cylinder and this tool with brake fluid for lubrication and let it go to work.... Freaking awesome results!!!! I got the 120 grit one, so once I get the OEM rebuild kit here, I will do a test fit and if things look snug, I will get the 320 grit brush and finish it up. Very happy to finally be able to move past the roadblock and get onto other stuff on this bike!!!

I used this to clean up the slide hole on a caliper on a 13 gmc 2500HD. Worked good and cleaned it right up. Wish I thought of using one of these sooner! I did notice a bit of wear on the stones after one use but not overly concerning.

There was nothing to dislike safe and easy to use takes guesswork out of cylinder honing

just what I needed
