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

Worked great for what I needed, it is important to know how to use this tool before you try to use it. And it’s suggest using 10W-30, I saw some use transmission fluid, I actually used vegetable oil with great results.

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 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.

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.

Tried using a hone on a motorcycle bore but it was going to be slow going. Used the Flexhone and it did a beautiful job of crosshatching the glaze. Had to be careful as it was a bit aggressive but did the job so quickly it was a real pleasure to use.

I was putting in new rings, but had a glaze on the cylinder bore. this quickly removed the glaze and will allow the new rings to seat properly.

Great

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.

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

East to use great tool for the price.
