FAQ
Q1: Is this air screwdriver suitable for auto tire removal or heavy machinery repair?
A: The W50151 has a max torque of 20 N.M, which is ideal for light to medium industrial assembly, electronics/furniture assembly, and general maintenance. For heavy-duty tasks like tire removal, we recommend using a professional impact wrench with higher torque.
Q2: What is the air pressure and consumption requirement?
A: The tool features a standard 1/4″ air inlet. To achieve the 8000 RPM speed and 20 N.M torque, a stable air source of 0.6-0.8 MPa (87-116 PSI) is recommended. An oil-water separator is also advised to extend the tool’s lifespan.
Q3: What is the Minimum Order Quantity (MOQ)?
A: Our standard packing is 1 pc/box and 20 pcs/carton. Mixed orders with different hand tools or pneumatic tools are supported. Please consult our sales team for specific MOQ details.
Q4: Is the bit easy to change?
A: Yes, it features a standard 1/4″ quick-change chuck. Simply insert the bit and pull down the sleeve to lock it; pull up the sleeve to release the bit. It is very convenient.
