(Also known as Pneumatic Reciprocating Lapper / Air Filing Tool / Precision Air File — Low-Vibration Type)
A Low Vibration Air Lapper and File is a pneumatically powered precision finishing tool designed for lapping, filing, deburring, and fine surface finishing of metal, plastic, or mold components — while significantly reducing vibration and operator fatigue. It operates using compressed air to drive a reciprocating (back-and-forth) motion of a fine abrasive stick, file, or stone, allowing controlled removal of small amounts of material with excellent surface accuracy. The low-vibration design uses internal counterbalance mechanisms and damping materials, making it ideal for long-duration mold finishing, die polishing, and precision repair work in tool & die, aerospace, and manufacturing industries.
