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

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.

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.

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

I used this on my 2004 Tacoma when putting in new leaf springs. I needed to clean and grind down a lot of rust on the inside of the shackle that the leaf spring bolt attaches to. This fit, and worked, perfectly! I went a few sizes up on the diameter of the hone versus the hole to be honed so there would be some additional friction and I could get it as smooth as possible. Attached it to my handle held drill and went to town. Would definitely order it again if I needed it!

Used this for my nikasil cylinder on my Crf250r. Only did 6 passes to get the glaze off the cylinder and it worked perfectly.

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.

Purchased 76mm for honing an old ATV cylinder. Some WD40 and several passes later the bore is cleaned up and has a nice surface for the new piston rings to seal in. Cleanup is easy with carb or brake cleaner. Make sure to get the right size hone for your bore!
