Specification OP-12AK
The Onpin OP-12AK Air Tapper is an industrial-grade pneumatic hand tool designed for high-precision internal thread tapping, driven by compressed air at a standard operating pressure of 90 psi (6.2 bar). Featuring a gear-driven mechanism coupled with a low-runout B12 taper spindle, it delivers high torque performance at a controlled speed of 100 RPM for heavy-duty manufacturing tasks.
Key Features of Onpin OP-12AK
- Gear-Driven Mechanism: Provides smooth power delivery and durable performance under heavy continuous loads.
- B12 Taper Spindle: Features a low runout design to maintain high thread accuracy and prevent premature tap wear.
- Torque Collet Protection: Essential for blind hole tapping, shielding the workpiece from damage and preventing tap breakage.
- Single-Size Dedicated Collet: Employs one collet per size, optimized for dedicated single-size repetitive tapping operations.
- Push-Type Forward/Reverse Switch: Enables seamless one-hand operation for quick forward and reverse direction switching.
- Rear Exhaust Design: Directs exhaust air away from the working zone, ensuring clean workpieces and enhanced operator comfort.
- Support Arm Integration: Highly compatible with reaction arms or robot arms to enhance stability during high-torque operation.
