SPEEDAIRE 21AC06 Engraving Pen
The SPEEDAIRE 21AC06 is a pneumatic engraving pen designed for general-purpose marking tasks. It operates at a maximum of 13,000 strokes per minute and includes one standard tip for immediate use. The tool requires a compressed air supply rated at 90 psi and consumes 1 cfm during operation. It suits technicians and hobbyists needing a lightweight, air-driven stylus for detail work.
1/4 in NPT Air Inlet and Hose
The pen features a male 1/4 inch NPT air inlet and requires a minimum 3/8 inch hose for proper airflow. A 59 inch hose length is provided, offering reach around a workbench without excessive slack. The tool body measures 6 3/4 inches long and incorporates a cushion finger grip to reduce fatigue during extended engraving sessions. The fine-point stylus allows precise control on metal, glass, or plastic surfaces.
90 psi Pressure and 1 cfm Flow Limits
Performance is bound by the 90 psi pressure requirement and 1 cfm average flow rate; insufficient compressor capacity will reduce stroke speed and marking depth. The single included tip limits tip-profile variety unless additional accessories are sourced separately. The tool is restricted from sale in certain jurisdictions due to chemical content warnings. Users must verify local regulations and ensure their air system delivers consistent pressure at the inlet.
