Specification OP-08AK
The Onpin OP-08AK Air Tapper is a heavy-duty pneumatic hand tool designed for industrial internal thread cutting, powered by compressed air at a standard operating pressure of 90 psi (6.2 bar). Featuring a robust gear-driven structure combined with a low-runout B12 taper spindle, this equipment delivers exceptional torque output and high precision for continuous production line environments.
Key Features of Onpin OP-08AK
- Gear-Driven Mechanism: Ensures stable power transmission and long-lasting durability under demanding workloads.
- B12 Taper Spindle: Engineered with low runout to achieve precise thread geometry and prevent premature tap wear.
- Torque Collet Protection: Designed for blind hole tapping to safeguard workpieces from damage and minimize tap breakage.
- Single-Size Dedicated Collet: Utilizes one collet per size, making it ideal for streamlined, single-size production tasks.
- Push-Type Forward/Reverse Switch: Enables seamless, one-hand operation for quick directional changes during tapping.
- Rear Exhaust Design: Directs exhaust air away from the working zone, keeping the workpiece clear of debris and enhancing operator safety.
- Support Arm Compatibility: Easily interfaces with reaction arms or robot arms to improve operational stability and reduce operator fatigue during heavy-duty tapping.
