Review on Research FLEX HONE Cylinder Abrasive Diameter Abrasive & Finishing Products for Finishing Products by Jesse Azuse

Excellent product. Abrasive brushes are a very good thing and BRM makes the most of them. The price on Amazon is the same as everywhere else, so nothing to complain about. I used this particular honing machine on a stock small block Ford engine block to hone the cylinders before installing the pistons and rings. The 180 grit worked great with the standard iron piston rings. If you're using molybdenum rings or anything else, follow the manufacturer's recommendations when choosing a grit. I also like honing brushes because you can buy one for less than at a mechanical shop to sharpen your cylinders and you can usually make more than one block with one. The last BRM sharpen I did had 5 small blocks and still has life in it. take it how you want A very good product at a very good price. Definitely recommended for your restoration or re-ring project!
