Milwaukee M12 Surge hydraulic impact Cordless Drill Reviews & Impact Drivers

Milwaukee M12 Surge Hydraulic Impact Driver

Having already reviewed the Milwaukee M18 Surge impact driver, seeing the new Milwaukee M12 Surge hydraulic impact driver at the 2019 NPS media event gave us a pleasant surprise. The new impact driver is the first 12V subcompact hydraulic driver on the market.


How It Works

The Milwaukee M12 Surge impact driver uses a hydraulic powertrain instead of a metal-to-metal impact mechanism. More traditionally, we call this oil impulse technology, and the tools deliver much less noise and vibration than traditional impact drivers using anvils. They also maintain their peak torque longer than standard impact drivers due to a longer strike duration. They tend to hit slower, but harder, to deliver a more even, and often faster, driving speed over traditional impacts.

The M12 Fuel Surge hydraulic impact driver should work well for driving small to medium diameter fasteners. It also seems like a great MRO tool to handle a variety of tasks. This tool makes a lot of sense for anyone already on the Milwaukee M12 platform. Anyone looking for the power and flexibility of an impact driver, but with less noise should also take a close look at this tool.

Since the Milwaukee M12 Surge runs quieter than standard impact drivers, it works really well indoors. It seems particularly well-suited for any work done in an occupied building or for close quarters work. It’s only too bad it wasn’t around in time for our best hydraulic impact driver shootout.

First of Its Kind?

While this tool certainly isn’t the first cordless hydraulic impact driver on the market, it is the first 12V tool using this technology. We already prefer 12V or subcompact tools over 18V for MRO work or anything that doesn’t require the bulk or premium power of 18V tools.


The Nitty Gritty

This tool can drive fasters at higher setting speeds over a standard impact—in many applications. , and 450 in/lbs of sustained torque, the new tool delivers unmatched performance.

Final Thoughts

We think the Milwaukee M12 FUEL Surge hydraulic impact driver should be a real hit with anyone already on the M12 platform. With a proven brushless motor, three driving speeds, and a self-tap mode, you get precise control. Combine that with reduced noise output, and this makes for a compelling purchase.

The new M12 Surge impact will go on sale starting in August 2019 for $149 (bare tool) or $199 (kit).

Nice! If my m12 impact ever craps out, I’ll replace it with this guy.
