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

Worked great, as expected.

Works like a dream!

It has a large surface area for big or small jobs. Great looking quality. Balls did not easily chip in shipping as some hones do.

I have a 2005 Honda CRV that was burning one quart of oil per tank of gas. YES you did read that correctly. Car was abused before I got it, but now I have to fix it. Pulled the engine apart and found scoring on the #4 cylinder wall and a damaged piston. Replaced all 4 pistons, rings, and rod bearings. Took this hone to all the cylinder walls with a little extra in #4. All the bores came out factory perfect, except #4 which I would give a 8 out of 10. You could still see some vertical lines but it was 95% better than before. Hondas stance is do not hone, just install rings, and if you can catch a scratch with your fingernail, the block needs replacement. Well I wasnt replacing my block, so this was the next best thing. Put it all back together and the engine runs perfect. Car does not burn a drop of oil and the oil is still golden. It would be black from blowby within 500 miles before. Very pleased! and highly recommended.

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.

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

Excellent product will recommend to everybody

Exactly what I needed for 5.3 LS

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

Ive been using these honers for years. Hands down, the best money can buy. Cleans up various bores and preps the cylinders with nice cross-hatching.
