great hone I,ll use it for years !

Did A super job on my cylinders, may last for ever.

Great

Spec was crosshatch 30 to 45 degrees. Profiled the wet sleeves first, they were all in spec, so went to town. Low speed drill, brisk in out action achieves great results. Lubricate the hone before every use. Go a little past the return direction so you reduce the low angles at the end of the stroke.

Using the correct size on the cylinder size has provided a good result. Forced an oversized one once and did not yield an easy result.

Excellent product will recommend to everybody

Worked very well

liked the hone, but yikes!, the price!
