Brush Research GBD40024 FLEX-HONE, 4 (101mm) Diameter, 240 Grit, Silicon Carbide Abrasive (Pack of 1)

Expensive, but did a professional job honing my jeep cylinders.

Worked great, as expected.

worked real good.Used it on a ford flathead motor

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.

This is the only way to go. Just get the right size for your cylinder

Works awesome, followed directions on the box and was very easy to use. Using 10/30 oil, coating the cylinder and tool liberally, using the lowest speed on the dewalt. Using a fast in and out motion with a quicker pace for the last 3 seconds or so, got that nice 45 deg cross hatch pattern. One ball was missing from its wire so I cut that wire off flush, as to avoid any scoring of my cylinder walls.

Exactly what I needed.

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.

If you know what this then you know what it’s supposed to do. This one do exactly that

I still use this to restore my Onan p218 and p220 engines.
