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

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

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.

Exactly what I needed.

Great

Great for refreshing any EJ25, they have a 99.5MM or 3.91 inch bore for the 4 inch hone works great for them. I have done 2 of them now, put the drill on low speed and squirt oil on them as you go will give good results.

Got the job done

Perfect

Excellent Hone, does the job for me.

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.

Worked great for honing a Ford 289 .030 over. If using an electric drill, swap batteries after the first bank.
