Cylinder Honing Tool Jonnesway AN020007 for 57–177 mm Bores

Jonnesway cylinder honing tool AN020007 is engineered for precision honing of engine and hydraulic cylinders with bore diameters from 57 to 177 mm. The tool delivers controlled abrasive action to remove light scoring, glazing and minor surface imperfections while restoring roundness and producing a consistent crosshatch finish. Designed for workshop use, it enables accurate surface preparation of cylinder walls before piston ring fitting and reassembly of automotive, motorcycle and industrial engines.

Advantages

The adjustable expansion mechanism provides uniform contact with the cylinder wall across the full 57–177 mm range, enabling consistent material removal. Hardened components and durable abrasive fittings ensure stable operation and long service life under workshop conditions. The tool’s design allows fine control of honing pressure and stroke, helping to achieve the desired crosshatch angle and surface roughness required for reliable sealing and oil retention.

Suitable for

• Reconditioning engine cylinders in cars and motorcycles
• Honing hydraulic cylinders and industrial bore components
• Preparing cylinder walls prior to piston ring replacement
• Precision workshop and maintenance operations requiring controlled surface finish

Key specifications

• Bore diameter range: 57–177 mm
• Adjustable expansion mechanism for uniform abrasive contact
• Compatible with standard honing stones/abrasive sticks
• Durable metal construction suitable for workshop environments
• Designed for manual or machine-driven honing spindles

How to use

Mount the honing tool in a suitable driving spindle or handle according to the workshop equipment instructions. Select an appropriate abrasive stone for the material and condition of the cylinder, then expand the tool until the abrasive contacts the bore surface with light, even pressure. Perform slow, controlled up-and-down strokes while rotating the tool to generate an even crosshatch pattern; periodically inspect the bore and change stones as needed to progress from coarse to fine abrasive. Clean the cylinder thoroughly after honing to remove abrasive residues and metal particles before reassembly.

Usage recommendations

Use cutting fluid or honing oil compatible with the bore material to improve abrasive performance and reduce heat. Measure bore diameter and roundness at intervals during the process to avoid over-honing. Store abrasive stones and the tool in a dry, clean place and replace worn stones to maintain effective honing results.
