FLEX-HONE® tools are widely used across industries to remove surface rust and corrosion from internal bores while simultaneously refining the finish without removing excessive base material. Their unique design features abrasive globules mounted to flexible nylon filaments that gently hone and polish cylinder walls, restoring functionality and improving surface characteristics.
Overview
In the metalworking industry, removing rust and corrosion from cylinders is a critical step in maintaining part integrity, ensuring optimal surface finish, and extending component life. Cylindrical components used in engines, hydraulic systems, pneumatic actuators, and firearm barrels are especially prone to oxidation due to exposure to moisture, chemicals, and operational wear.
Surface contamination from rust not only degrades material performance but also interferes with tight tolerances, proper sealing, lubrication retention, and coating adhesion. Restoring a clean, uniform surface finish helps prevent premature failure, leakage, and costly downtime across a wide range of industrial applications. FLEX-HONE® tools deliver a consistent, crosshatched finish that not only removes corrosion but also enhances surface performance, making them a valuable solution in cylinder restoration and preventive maintenance programs in the metalworking sector.
