An impact wrench earns its keep the first time it spins off rusted lug nuts or suspension bolts in seconds. Value means enough fastening and breakaway torque for your jobs, a battery and charger in the box if you need them, a brushless motor for runtime, and a warranty you can rely on. A tool-only pro wrench can be cheaper if you already own the batteries. We put 61 1/2 in impact wrenches on one spec sheet so you can compare what you get for your money.

We reviewed 103 impact wrenches and kept only the 61 that pass every check below. Those are ranked by a Best Score built from spec fit for this job, warranty, sales rank.
These reviews are based on each impact wrench's published specifications and listing information, in the order of our Best Score.
DEWALT DCF900 kit with pro torque and a big battery
The DEWALT DCF900P1 leads our Best Score at 75. It delivers 1030 ft-lbs of max fastening torque and 1400 ft-lbs of max breakaway torque, enough for lug nuts, suspension bolts, crank bolts and heavy equipment. It is a brushless 1/2 in wrench, and this kit includes a battery listed at 100 Wh.
Four speed modes and a variable speed trigger give control, and DEWALT designed it to help prevent overtightening and fastener run-off, which protects wheel studs and threads. A shock-absorbing battery guard reduces wear on the battery-to-tool connection, and an LED lights dark wheel wells.
The kit weighs 11 lb as listed with the large battery, so it is heavy to hold overhead for long. It carries a 3-year warranty, tied for the longest here. The DCF900 also joins the DEWALT 20V MAX system, so the battery runs other tools. For most buyers, it gives the best mix of torque, battery and backing for the money.
VerdictThe best value impact wrench on this page.
Compact Seesii kit with two batteries
The Seesii WH760 ranks third with a Best Score of 64. It is a 1/2 in brushless impact wrench listed at 738 ft-lb of torque in our data, and at 4.4 lb it is much lighter than the brand-name kits above, which makes it easier to use under a car or at awkward angles.
Its value comes from the box contents: two 4.0AH batteries and a fast charger, so you can swap and keep working. At just 6.89 in long it fits narrow, deep spaces, and an LED helps in dark wheel wells and engine bays.
Warranty is not listed in our data, and Seesii is a budget brand, so long-term durability is less proven than DEWALT or CRAFTSMAN. Still, for tire changes, lug nuts and general DIY repairs, two batteries and a compact body give a lot for the money. Check the seller's return policy before buying.
VerdictA light, complete kit that offers a lot for the money.
JESIMAIK Z1320, the lightest kit here
Fourth with a Best Score of 61, the JESIMAIK Z1320 delivers 1200 N·m, or 900 ft-lbs, of breakaway torque for stubborn lug nuts and rusted bolts. At 2.98 lbs and 8.3 in long it is the lightest kit in our top five.
It comes with 2 × 4.0Ah batteries, so you can swap to the second battery instantly instead of waiting on a recharge. A comfortable rubber grip and an LED light help in tight, dark spaces. It has a brushless motor for efficiency.
Three auto-stop modes, Precise, Buffered and Delayed, work in both tightening and loosening, which helps stop nuts from spinning off and rolling away or being overtightened. Fastening torque and warranty are not listed in our data. For lightweight, two-battery value, it is a strong budget pick. Its low weight also makes it a good second wrench for quick jobs, even if you own a larger one. Use impact-rated sockets and finish lug nuts with a torque wrench.
VerdictA light, well-equipped budget kit.
Milwaukee M18 FUEL for M18 battery owners
The Milwaukee 2967-20 completes our top five with a Best Score of 60. Milwaukee rates it at 1,000 ft-lbs of fastening torque and 1,000 ft-lbs of nut-busting torque when used with M18 REDLITHIUM FORGE batteries, and calls it the densest impact wrench in its class for better access in tight spaces.
Four-mode control gives a range of 0-3,000 RPM and 0-1,500 IPM, helping you match power to the job. An all-metal drive train adds durability, and a friction ring makes socket changes quick. It weighs 5.95 lb as a bare tool.
It is sold as a tool only, so it is best value for people already on the M18 platform. Its breakaway torque is lower than the DEWALT DCF900 on paper, but Milwaukee's FUEL line has a strong reputation with mechanics. If you own M18 batteries, it is a smart buy.
VerdictThe best pick for Milwaukee owners.
CRAFTSMAN V20 kit with enough torque for car work
Second with a Best Score of 64, the CRAFTSMAN CMCF940M1 offers up to 700 ft-lbs of max tightening torque and up to 1000 ft-lbs of breakaway torque. That covers lug nuts, brake jobs and most suspension work on cars and light trucks.
A brushless motor gives better runtime and efficiency, and the kit includes a battery listed at 80 Wh. CRAFTSMAN describes it as a compact and lightweight design, though the kit weighs 10.25 lb as listed with the battery.
It carries a 3-year warranty, tied for the longest on this page, and joins the CRAFTSMAN V20 battery platform with drills, saws and outdoor tools. It has less torque than the DEWALT, but for home mechanics who want a reliable brand-name kit at a lower cost, it is excellent value. Use impact-rated sockets with it, since standard chrome sockets can crack under impact.
VerdictThe best mid-price kit for home mechanics.
Best among the reviewed tools
Fastening torque is how hard it tightens; breakaway torque is how hard it loosens stuck nuts. For lug nuts, 500 to 700 ft-lbs breakaway is plenty. Trucks and rusted bolts need more.
Kits with a battery and charger cost more but are ready to use. Bare tools are cheaper if you already own the brand's batteries.
Weights here run from about 3 lb to 11 lb with battery. Lighter, shorter wrenches fit wheel wells and engine bays more easily.
Speed modes and auto-stop help prevent overtightening and spun-off nuts. A 3-year warranty adds value; several budget models do not list one.
Most car lug nuts are tightened to around 80 to 100 ft-lbs. An impact wrench with 500 ft-lbs or more of breakaway torque removes them easily, even when stuck.
For occasional tire changes and DIY repairs, budget kits with two batteries offer good value. For daily use, a brand-name tool with a warranty lasts longer.
Use it to run nuts on, then finish with a torque wrench to the correct spec. Impact wrenches can overtighten and stretch studs.
1/2 in wrenches suit lug nuts and suspension bolts. 3/8 in wrenches are smaller and suit engine bay work. All picks here are 1/2 in.
