Brush Research FLEX-HONE Cylinder Hone, GB Series, Silicon Carbide Abrasive, 4-1/8 (105 mm) Diameter, 240 Grit Size

I have a 3000 mile freshly rebuild 355 sbc. Went with new rings rods and pistons.. A quick Hone to knock the glaze off was exactly what it needed. Does a great job !!

Should be in all tool boxes

There is nothing to dislike about this hone. It does exactly what it is suppose to do. Been using these hones on motorcycle cylinders for years and they work great everytime.

did what i wanted. i use constant water vice oil for honing since i want to get rid of the what im scraping off. this was a little big for my little guy (1989 CIVIC HATCH) but it worked perfectly. and it doesnt look like it is worn out so its not one time use. unless you are trying to take off alot of material.

Worked wonders!!

Worked fantastic to hone a 4.7 HO from an 02 Grand Cherokee. I used 5w-30 as the lubricating oil (it says on both their website and the instructions on the box that you can either use their cutting oil or just a normal 5w-30 oil), put a couple sheets of cardboard below the engine block and went to it. Watch a few videos on how to do it and the rhythm to use to achieve your correct cross hatching pattern and youll be good to go. It took me two cylinders to get it right where I wanted it and then I was golden. Make sure when doing it, you use the hone as little as you need to so you dont overdo it (Not really sure if you could, but thats the general rule Ive always heard with these and figure it cant hurt to go by it).

Couldnt find in stores, these are great for mild rebuilds. Cleaned up cylinders in just a few passes. Use care cleaning up as grit and tool material gets everywhere.

deglazed my cylinders, and got it to work with my engine still in the car. only had to shorten it up

Works very well - easy to use if careful.

worked good nice cross hatches.
