Review on 🔧 Adjustable Engine Cylinder Hone Tool - EWK 1-1/4 to 3-1/2 Inch 3 Stones, Deburring Piston Honer with 220 Grit by Alfredo Nosrac

Used on a 50cc cylinder. It was a 2-stroke engine and stones got stuck in the intake/exhaust ports. A ball grinder might have worked better, but with a little attention to detail, this worked well. The stones were aggressive enough to create the pattern of shading desired. The shank has a flexible part with a spring that keeps the sharpness in the cylinder even if you don't hold the drill perfectly straight. It is adjustable so you can use it for multiple. Are you still listening? Just buy the damn thing.
