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

We needed this tool for rebuilding motors. Worked great.

Awesomeness

Worked great would buy again

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

USED THIS FOR AN LS2 AND AN LS3. WORKED GREAT FOR BOTH. Some learning curve, but definitely adjust the crank as you go or you could slightly scuff it like I did. Not enough to cause a major issue, but did need to use 2000 grit sandpaper and wd40 to wet sand. thats user error. not the product.

Worked as expected

Works great. Did a nice cross hatch pattern.

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.

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.

Used this hone on my 4.030” 351W and am very pleased with the results. About 30 seconds in each cylinder with a little motor oil Is all I needed. Worked great.
