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

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

Worked great

Perfect product, great description about getting the right size for my cylinder. Thanks

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.

Quickly gets the job done It was easy to get cross hatching

Was easy to use

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.

Worked great

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.
