Electric nutrunners: “Za Rulem” experts have chosen the best one
We found out how easy and convenient it is to unscrew nuts on wheels. with a budget wrench or a conventional wrench.
There is no sense to buy a professional nutrunner just to use it a couple of times a year: it is too expensive. So for the test we picked up a “budget” company of four tools priced from 2000 to 7900. All impact wrenches are low-voltage: two are cordless and two more are externally powered by the vehicle’s onboard power system. You can use these on the road.
The real tightening torque for wheel fasteners on cars is 100-120 N-m. Sometimes even higher power is needed, e.g. to tighten the hub nut or to unscrew rusted joints. The company we bought has declared torques of 140 to 380 N-m. Let’s find out if these promises are true! And in order not to break bolts by accident while testing, we took a more powerful fastener from GAZelle and under it a massive head of 27. It reduces the power of wrenches, but all tools were tested under equal conditions, so tests with “weights” are correct.

Designed for difficult-to-reach screws and fasteners.
- Country: Japan
- Torque: 60 Nm
- Impact frequency: 3000 beats/min

DeWALT cordless tools generally succeed. unless, of course, we’re talking about the budget series. This impact wrench is a real monster, capable of producing up to 950 Newton-meters of torque. Few cordless models rival it. except the Makita DTW1001RTJ. Naturally, this kind of thrust is not always needed, so a three-speed gearbox is used here.
Best Cordless Compact? Dyno Says It’s Not Close: Makita & Ridgid vs M18 & DeWalt Ep54
“The heart of the tool is the traditional DeWALT 610 watt brushless motor with effective cooling. For impact wrenches, this is no small thing: they often have to work at maximum power and then the winding must be allowed to cool down quickly. The DCF899P2 fits well in your hand, the rubber pads are comfortable. Of course, the weight is felt, but it is also good. it is fatal to save on metal with such characteristics. And for the nutrunner “death” is quite literal. So Boris Razor is, as always, right: heavy is good, heavy is reliable.”.
It is powered by 18 volt brand batteries with 5 amp-hour capacity. The set includes two of them, that justifies the price to a certain extent. we already got used to the fact that the beautiful figure on the price tag usually means that neither batteries nor charger are included. Here everything is in place. However, please note that the tool runs out of them quickly. a powerful motor requires its.

Frequently Asked Questions
Question: What is a pneumatic impact wrench??
Answer: an air impact wrench is a compressed air powered mechanical tool designed to tighten and unscrew any type of fastener. What “impact wrench” means is clear from the answer to the following question.
Question: How does a pneumatic impact wrench work??
Answer: The pneumatic impact wrench doesn’t just provide more power in terms of rotational motion (like an electric drill). Most of the torque is transmitted through the rotating masses inside the impact wrench.
These masses release their energy in the form of impacts that pass through the bit into the bolt. This gives more power to unscrew or tighten bolts and nuts without hurting your hands.
Q: What type of air compressor is needed?
Answer: To determine this, you need to know the recommended PSI and CFM values for your air impact wrench. You need a compressor that is about 1.5 times higher than this.
For example, if a wrench needs 5 CFM at 90 PSI, your compressor should provide 7.5 CFM at 135 PSI.
Question: What are PSI and CFM??
Answer: PSI is unit of air pressure, psi. CFM is the unit for volumetric air flow, cubic feet per minute.
