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

I use it for cleaning up a ported cylinder

Used this for refinishing a plow piston cylinder. A lot of people complaining about the price but this is much cheaper than any other available option, whether sending out to get machined or buying and actual hone setup for at home.

just what I needed

This is an easy way to remove a small amount of metal from cylinders. It creates a smooth surface. I would recommend this item to others who wish to enlarge the inside of a cylinder.

I have six of these now, and I buy a new one if I need a size I dont have. They work perfectly to take the glaze off of a motorcycle cylinder before installing a new piston and/or rings. They are sturdy, and last a very long time if treated well. Pro Tip: Dip them in transmission fluid before honing.

Honed a Golfcart cylinder in no time, removed fine scratches and ridge at top of cylinder in under 5 minutes. Pricey but cheaper than a machine shop and frankly equal results for all I needed.

Used the 3” 240 grit. Did an amazing job on the steel sleeves in this machine for a set of SPI pistons. Compression and performance are still spot on after 800 miles of use. Definitely would recommend.
