Acymner Engine Cylinder Hone Tool | Adjustable 2-7 Inch Deglazer with 3x 220 Grit Stones

Overview

The Acymner Engine Cylinder Hone Tool is a practical deglazer designed to refresh bore walls in gasoline and diesel engines. It supports a wide bore range from 2 to 7 inches, letting you prep everything from compact motorcycle cylinders to larger automotive blocks with a single setup. The three 3-inch long 220 grit stones deliver controlled material removal when used with light, steady pressure. A knurled wheel adjusts stone tension, while a self-centering mounting keeps contact even across the bore for a smoother surface. The tool is drill-compatible, so you can leverage a standard electric drill for power without needing specialized equipment. Thoughtful design and robust construction aim for reliable performance across jobs, with reuse in mind through replaceable stones and durable metal components.
