Alloyman 1/2" Cordless Impact Wrench Kit vs DeWalt DCF900 Impact Wrench

Buy the DeWalt DCF900 if you want a proven high-torque wrench with a huge battery ecosystem, a built-in LED light and a track record owners trust. Buy the Alloyman if you want the highest claimed breakaway torque and a complete kit with sockets and charger in one box. On paper the Alloyman claims more torque, but owners report it is very heavy and that the real torque falls short of the claim, and the included sockets are not impact-rated. The DeWalt is the safer long-term pick for regular shop or driveway use.

  • Choose the Alloyman if you want a ready-to-run kit with battery, charger and sockets and the highest advertised breakaway torque for the least outlay.
  • Choose the DeWalt if you already own DeWalt 20V batteries or want a lighter, well-supported wrench with an LED light and a long parts and service network.

What reviewers say

Alloyman 1/2" Cordless Impact Wrench Kit

  • 4.8 / 5393 ratings

Owners rate it highly and mostly talk about power and value. Many say it breaks loose lug nuts and rusted bolts with little effort, and they like the three speed settings and battery life. The main complaints are weight, torque that some feel falls short of the claim, and weak included sockets.

What people mention
  • PowerMixedBuyers praise the breakaway force on lug nuts, but some say it does not match the 1500 ft-lbs claim.
  • WeightCriticisedOwners describe the tool as very heavy, which wears on you during extended use.
  • Speed settingsPraisedThe three modes let users dial power down for smaller fasteners and up for stuck bolts.
  • BatteryPraisedUsers report good runtime from the 4.0Ah pack and a recharge of about two hours.

DeWalt DCF900 Impact Wrench

Owners and reviewers rate the DCF900 as one of the strongest cordless impact wrenches available, with torque that handles truck lug nuts and rusted bolts. Most complaints center on its weight and size rather than performance.

What people mention
  • TorquePraisedOwners say it breaks loose lug nuts and rusted bolts that mid-torque wrenches stall on.
  • WeightCriticisedReviewers call it heavy, especially with a large battery, which tires arms on overhead work.
  • SizeMixedThe compact body helps, but the large head still struggles in tight engine bays.
  • Battery platformPraisedBuyers like that it shares DeWalt 20V MAX batteries with their other tools.

Questions and answers

Which is better for removing stuck lug nuts?
Both will break most passenger-car lug nuts. The Alloyman claims more breakaway torque, but owners report it delivers less than advertised. The DeWalt's 1400 ft-lbs is well proven in real use.
Which lasts longer?
The DeWalt has the better record for durability and parts support. The Alloyman's weak point is its included sockets, which owners say crack under load; swap them for impact-rated ones.
Is the Alloyman worth stepping up to over the DeWalt?
Only if you want a full kit in one box and the higher torque claim matters more than brand support. For regular use, the DeWalt is the safer buy.
Do I need to buy batteries for the DeWalt?
Most DeWalt listings are tool only, so budget for a 20V MAX battery and charger unless you already own them. The Alloyman kit includes both.
Which is easier to handle overhead or under a car?
The DeWalt at 6.4 lbs is the lighter of the two, and owners describe the Alloyman as very heavy. For long jobs overhead, weight matters more than the torque gap.
