awesome---cleaned up a 7 inch bore cylinder 10 feet long and shows little wear---highly recommend

Worked as expected

These are the best brushes for honing your cylinder walls. I got nice 45 degree hone marks. It works VERY fast you put your drill on low speed and try to time it so you get the right degree of marks. It leaves a TON of residue so plan on power washing your block with cleaners. 3 to 5 passes is all it takes to clean up the walls. Remember you are removing glazing not boring your cylinder wall.

Worked great on refreshing crosshatch pattern on a 5.3 GM with 225k miles. Very effective with light effort.

Great part when doing cylinders on refresh build. Thanks

Perfect

Good tool

It has a large surface area for big or small jobs. Great looking quality. Balls did not easily chip in shipping as some hones do.
