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.

Liked this product so much, I bought 3
We use this one key impact for torqueing lugs in an electrical assembly that requires a set torque value to be achieved consistently. Used expensive torque products that were twice as loud and 3x the price. Because of all the other Milwaukee products we use in the shop, I researched the one key. I found through watching some videos that through the app you can really fine tune and set your specific torque required, it is very accurate.

I have been a Milwaukee user for 15yrs, I recently purchased a new m18 brushless impact kit. The quality is amazing as usual. I have had many of there impacts over the years and this one looks like they have added many improvements.

Used the new driver to fix some things on my boat. Compact size made it easy to get into tight places and powerful enough to do exactly what was necessary. Wish I had bought one of these a long time ago.
