The Matair Reversible Air Drill is a powerful industrial-duty pneumatic drill designed for sustained heavy-duty work in automotive, engine assembly, and fabrication environments. It features triple idler planetary gearing for smooth, reliable operation with extended tool life, and a 10mm (3/8") chuck capacity with 1800 RPM free speed for fast drilling and fastening. The teasing throttle provides precise speed control, while the handle exhaust design reduces noise and diverts air away from the workpiece—ideal for electricians, mechanics, panel builders, and industrial maintenance teams.
