We've been sourcing this 21V brushless impact wrench for about six months now, and it's pretty much become our go-to for mid-range automotive and construction work—the ZC3002 delivers a solid 300N.m of torque without the cord hassle.
It hits 0-3200 impacts per minute at no-load speeds up to 2800 RPM, and the 4.0Ah lithium battery usually runs through a full shift of light fastening, though heavy bolt removal will drain it faster (check lead time on spares). The charger tops up in 1-2 hours, which is decent for price point.
Most buyers use it for tire changes, suspension work, or assembling steel structures, but it's actually not great for continuous high-torque applicaions like breaking rusted truck lugs—you'll want a pneumatic for that. Teh brushless motor keeps it compact at 33.5cm long, so it fits in tight engine bays.
CE and RoHS certified, and we've had zero returns on the 6-month warranty so far—the housing feels sturdier than some of the cheaper 20V models we tested. One thing a buyer might not think to ask: the trigger has a variable speed control that's surprisingly smooth for a sub-$100 unit.
MOQ is typically 50 units or so, and we usually have stock, but confirm lead time if you need more than 200. Anyway, the twin-battery kit is what most go with—the single-battery version is lighter but you'll regret it on a long job.
It delivers 300N.m of max torque, which is plenty for most car and light truck lug nuts. You should be able to zip off standard passenger vehicle wheels without a breaker bar.
Yes, the package includes two 4.0Ah 21V lithium batteries plus a charger, so you can keep one charging while you work.
It's CE and RoHS certified. We can provide copies of those certificates upon request—just ask your sales rep.
Our standard MOQ is 50 units for this model, but we can discuss lower quantities for first-time trial orders.
Charging takes about 1 to 2 hours depending on the battery level. No, you cannot use the wrench while the battery is on the charger—you'll need to swap in the second battery.
