Brush Research FLEX-HONE Cylinder Hone, GB Series, Silicon Carbide Abrasive, 4-1/8 (105 mm) Diameter, 240 Grit Size

worked perfect to deglazed cylinder wall on 2003 Ford Focus 2.0L SPI , also known as the dropped valve seat engine SOHC. Adds a nice crosshatch to cylinder. Directions for use were on end of brush box.

Fast, easy to use. I lubricated with transmission fluid. Took glaze off fast and left nice crosshatch. You must move quickly up and down. Lubricate hone between each cylinder.

I made sure to order the correct size. I modified the end by grinding off the nub so I could get closer to the pistons. It worked excellent. The stones are quality, I sprayed with WD-40 and it made quick work of it leaving a beautiful cross hatch pattern deglasing perfectly.

Used to hone cylinder bores on engine rebuild. Nice cross-hatch finish.

Being a hobbyist rebuilder I am very happy with the results of this hone. Makes up for a mulittude of errors on my behalf in skill. I have a Lisle rigid hone and that works really well for the rough work but this made the final a finish factory finish. Seated perfectly

Easy to use and did the job perfectly. Will be getting more when I need them.

I was very pleased with how well that this brush worked. I had one of these hones for over 20 years until someone borrowed it and never brought it back. What I am trying to say is that this is a very high quality hone, and will last a long time

Worked great for a stock bore 5.3/4.8 vortec

Easy to use.

Havent used it yet but will be fine.
