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

Yes

Works great, just remember to use oil or it gets aggressive.

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.

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

Bought this to rebuild a LS 5.3L. 5 seconds in each hole on low speed. Perfection!

Worked really good on 6.0 lq4 engine rebuilt, easy to use with plenty of lubricant.

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

It works perfectly

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.

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