Two-Bearing Air Engraving Pen · Model: RH-010K2

Model: RH-010K2 气动空气抛光研磨笔套装
The RH-010K2 Pneumatic Polishing Grinding Kit / Set (Model RH-010K2) 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.
