Specification
What is ONPIN OP-G2220 Air Die Grinder?
The ONPIN OP-G2220 Air Die Grinder is a extended-reach handheld pneumatic tool powered by compressed air at a operating pressure of 90 psi (6.2 bar / 6.3 kg/cm²). It operates by converting pneumatic pressure into high-speed rotational energy via an internal rotor motor to drive the collet chuck for deep-reach grinding, deburring, and surface finishing. Designed with an extended 320 mm (12.59 inch) overall length, the ONPIN OP-G2220 is tailored for hard-to-reach industrial applications.
Key Features of ONPIN OP-G2220
- Powerful Motor Output: Driven by a 1 HP (746 W) rotor motor that maintains strong torque under heavy-duty continuous operations.
- High Free Speed: Delivers a free speed of 20,000 rpm to achieve smooth surface finishes and optimize machining efficiency.
- Extended Body Design: Features an overall length of 320 mm (12.59 inch), allowing operators to easily reach inside deep cavities, pipes, and narrow spaces.
- Standard Collet Size: Equipped with a 6 mm Chuck Size, making it compatible with standard carbide burs and grinding accessories.
- Industrial Air Standard: Uses a 1/4 P.T air inlet and a 9.5 mm (3/8 inch) hose size while consuming 410 l/min (14.5 cfm) of air for consistent power delivery.
