3/8" Reversible Air Drill, Double Bearing Spindle

【Double Bearing】The main shaft structure supported by a double bearing creates a two-point support system that reduces radial runout and improves concentricity for consistently high-quality holes in metal panels.
【Reverse】An integrated forward/reverse lever allows for instant change of rotation direction, facilitating the removal of jammed drill bits, tapping, or chip evacuation in deep holes during repetitive manufacturing tasks.
【1.5-10mm Hardened Chuck】The hardened and reinforced three-jaw chuck provides 360-degree clamping force, securely holding 1.5mm to 10mm drill bits to prevent slippage during continuous operation at 1400 RPM.
【Stepless Speed Control】An integrated air valve with a stepless trigger allows the operator to freely adjust the speed from zero to 1400 rpm, offering precise drilling for pilot holes and controlled work on delicate surfaces. 【Compact Pistol Body】The lightweight pistol-grip design fits comfortably in one hand, reducing fatigue during long drilling, boring, and deburring sessions on body panels or assembly lines.
