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

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

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.

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 have personally relied on products from this company for a very long time in a professional setting. As far as ball Hones go Flex-Hone is the best and has been. The quality is top notch and the number of sizes they make are unequalled by any other company

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.

Great

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

Was easy to use
