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

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.

Exactly what you need to prep a new Nikasil cylinder for new rings. This will remove material quickly, which is what you need to set in a nice hash pattern in Nikasil. However, you only need a slow speed (low gear on most drills) and only 3 or 4 oscillating strokes. Good luck.

These are very easy to use Time will tell how long they last

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.

East to use great tool for the price.

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.

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.

Great
