Brush Research BC5818 FLEX-HONE®, 5/8" (16mm) Diameter, 180 Grit, Silicon Carbide Abrasive (Pack of 1)

Works great

I ended up not needing but it was as advertised.

Works as it should

Had a cylinder that the piston tings had rusted to from sitting outside for so long. This hone took all the rust right off and made the cylinder look real nice. I've never honed a cylinder before but it was easy and turned out great. I can't attest to the longevity of this only because I had used it on 2 cylinders. But for the 2 I did, it worked like a charm.

Great, did the thing

I used this with a drill to clean out outboard motor tilt tube that had rusted up and frozen my steering cable. I had to drive the rusted steering cable out and then used the hone tool to clean up the .625 inch bore and installed new steering cable (150 HP Mercury). Worked perfectly!

Honed a 70mm dirt bike cylinder. Worked well for a quick top end rebuild.

I use this to hone my hpa air gun tube great fit and works great on the discovery the qb 78 qb 79 also umarex gauntlet tubes. Make it smooth less chance of oring nicks.
