A quick comparison of the new Makita XWT17 Mid-Torque 1/2” wrench with the old XWT04. I haven’t used it a lot yet (just taken off some lug nuts doing a tire rotation), but here’s what I’ve noticed.
Aside from being substantially smaller (see pics), the new model is nearly 2lbs lighter — while having more than 50% additional torque (520 ft-lbs vs. 325 ft-lbs.)
What’s really noticeable, though, is the balance. The old model is VERY top-heavy. Even with a 5ah battery, it doesn’t balance at all; it’s always a chore holding it at an angle. The new model is almost perfectly balanced with the battery attached. It’s much easier to maneuver around obstacles and less tiring to use.
The other features (modes, torque limiting, etc) are just icing on the cake. I also much prefer the ring anvil as opposed to the pin anvil of the old wrench (the XWT18 has a pin anvil for those who prefer it.)
My only complaint is that they didn’t put the controls on the rear of the motor, where they would be easier to use.
We'll see how it holds up in the long term, but for my money it's already a winner.
