I used this hone on a BMW M20 rebuild out of a mid-80s E30. The hone worked perfectly. I first used the hone with an old 9.6V Makita cordless drill that, sadly, didnt make enough torque to get the job done right. I went out and bought a 6.5 amp Porter Cable 1/2 chuck drill and it cleaned up the cylinders perfectly. Note: if the hone starts to bind a bit, do your best to _not_ stop the drill from spinning. I learned (the hard way) that if the hone stops, and you (in your infinite wisdom, like myself) try to reverse the hone out, the metal braids that hold the hone balls in place will unravel. Youll spend more time than you car too putting the hone back together again (with or without all the kings men). Even though there is still life in the first hone I used, I ordered another one just to have on hand. Thats how much I liked this hone.

Worked Great !

Excellent item for the price.

Great for cleaning up cyl. Got another for smaller moter. I will get more as a good price keeps me coming back.

Used the 89mm size hone for my 84mm cylinders in my 52 motor and seemed to work good. Just lubed it up with some motor oil and followed instruction and the cross hatching seemed to come out really good, gotta speed it up on the last few strokes or else your cross hatches will not be close to 45 degrees which I found out quick enough.

Is and has always been a good product..

Used it on my 4.9 ford engine. It did a fantastic job.

Good tool for my VW 1600 rebuild! Took practice on an old detonated cylinder to get cross hatch just right. Practice first and use oil! Itll do the job quick and well.
