Model: RH-3170A 气动空气雕刻笔带软管
The RH-3170A Pneumatic Engraving Penwith Hose (Model RH-3170A) is a two-bearing air engraving pen for precise marking, etching and light deburring. Twin bearings stabilize the spindle so the tip tracks cleanly on metal, glass, stone and ceramic without chatter. It is popular for part serialization, jewelry work and mold finishing where a steady hand and a fine point matter. JIAJIE pens run at a controlled speed with minimal vibration, and the slim body is comfortable for long detail sessions. Carbide tips, collets and custom engraving-bit sets are available to match your process.
