Milwaukee 2857-20 M18 FUEL 1/4 in. Hex Impact Driver with ONE-KEY (Tool Only)

The M18 FUEL 1/4 in. impact driver with ONE-KEY is the fastest, most compact, and most powerful tool in its class. The POWERSTATE brushless motor produces up to 2,000 in-lbs of torque, delivering up to 30% faster driving speed, increasing productivity for the most demanding fasteners on the job. At only 4.59 in. in length, this is the most compact impact driver in its class, allowing better access in tight spaces. REDLINK plus intelligence ensures maximum performance while protecting from overloads, heating and over-discharge. The M18 REDLITHIUM battery packs (not included) deliver more work per charge and more work over the life of the packs than competitors. With ONE-KEY, users gain the ability to customize, track and manage their tool. Save up to 4 task settings directly to the tool. Self-tapping screw mode provides faster installation time, shutting the tool down as soon as the fastener is seated to reduce damage to fasteners and materials. Using the tool's tracking functionality, if ever lost or stolen, lock it out to protect your investment.

Yes we have 8 impacts
We use it for building pole barns to houses and it’s the only impact driver we found to screw in long spax screws. Great job Milwaukee. Now if you could get out the m18 framing guns a little faster. We need some real framing guns ASAP.

The best battery powered tools currently available
I use this driver at work to tighten and loosen connectors. My work is done outside with rough conditions for tools which includes rain, dirt, cold and hot weather. The Milwaukee tools power through and keep on going.............The battery life is the best of all the brands that I have tried. Buy Milwaukee, be happy.

Best impact on the market
I’ve been a metal stud mechanic for 30+ years and have been through countless screw guns in my career and the M18 Fuel is by far the best and most reliable one on the market bar none. The very first one that I purchased (approximately 7 years ago) is still operating, despite taking a 20’ fall. I for one won’t be using anything else besides my M18.

Reliable tools from a dependable brand
I and my crew really appreciate the reliability of the battery life and the power to drive screws and fasteners for hours. We haven’t any complaints on this driver as it is well balanced and feels lighter than the competition. Yes, we would recommend this tool to any that are looking for an industrial grade reliable tool from a brand you can count on!

Awesome Tool!
I use this driver everyday and am amazed by its weight to power ratio. I find myself grabbing this driver first for all by drilling and fastener installation. The 6" truss lock bolts we use to anchor our roof trusses go in quickly and effortlessly. I'm thoroughly impressed!

This impact, well... you just can't beat it!
Fast, powerful, smart, and versatile. This best describes the Gen 3 one-key. I have no problem with performance, but have had a few trials with one-key. It is a great app but I cannot get some things that the Gen 2 has. Otherwise, I'm very pleased.

Small changes
I use these drill everyday with the same 8 people. Some of the things we complain about are. The uncomfortable bet clip. The lack of storage for other bits. Maybe an all black version would sell allot
