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

Item is as it was described and we are extremely pleased with this purchase. Thanks again.

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.

Performed as needed

Worked as expected

Worked great!

Cleaned up my LS2 cylinders with ease. Get one, do it yourself.

new tech.?

Worked great, as expected.

Used the 89mm size hone for my 84mm cylinders in my 52 motor and seemed to work good. Just lubed it up with some motor oil and followed instruction and the cross hatching seemed to come out really good, gotta speed it up on the last few strokes or else your cross hatches will not be close to 45 degrees which I found out quick enough.

These things are awesome. makes short and nice work honing cylinders.
