Worked Great !

Great

This honing brush is easy to use, is high quality and worked just as described. You do need to ensure you move at a quick and consistent pace to get a good cross hatch. I recommend this tool for anyone looking to refresh and engine.

Got the job done

Amazing for auto engines

Good tool. Worked well.

Works perfectly

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 as expected

Worked very well
