Key Features
Heavy-Duty Drill PowerThe hammer drill in this kit delivers up to 1400 in-lbs of torque, so it is built for large holes, dense material, and demanding drilling and driving work without feeling underpowered. Quieter FasteningThe hydraulic driver runs 50% quieter than a standard impact driver with smoother driving and less vibration. That matters when you are working indoors, in finished spaces, or all day long. Compact M18 Combo KitThe Milwaukee M18 FUEL 2-Tool Combo Kit gives you a compact hammer drill at only 6.9 in. long plus a hydraulic driver, two 5.0Ah batteries, a charger, and a case in one ready-to-work setup.
Overview
The Milwaukee M18 FUEL 2-Tool Combo Kit, Model 3799-22, is a cordless drill and driver kit built for pros who need one setup that covers heavy drilling and fast, quieter fastening. This is a 2-tool cordless combo kit designed for drilling, hammer drilling, driving, and fastening. It combines the M18 FUEL 1/2 in. Hammer Drill/Driver with the M18 FUEL SURGE 1/4 in. hex hydraulic driver, then rounds it out with two XC5.0 batteries, a multi-voltage charger, and a carrying case.
The big draw here is that Milwaukee pairs two very different tools that solve two different jobsite problems. The hammer drill is the brute. Milwaukee rates it at up to 1400 in-lbs of torque with a 1/2 in. all-metal ratcheting chuck, 16 clutch settings, hammer function, and 2 speed settings. That gives you the kind of capability you want for larger bits, tougher framing work, and drilling into denser materials. The SURGE hydraulic driver is the control piece. It is meant for repeated fastening where noise, vibration, and user fatigue start to matter more than raw impact harshness.
What makes this kit stand out is how compact the hammer drill stays while still being the lead tool in the package. Milwaukee calls out a 6.9 in. overall length for better access in tight spaces and reduced fatigue. On real jobs, that matters when you are working between studs, inside cabinets, overhead, or anywhere a longer drill body keeps forcing you to change position. Add in the side handle and you get better control when the drill is doing the hard stuff.
On the fastening side, the M18 FUEL SURGE 1/4 in. hex hydraulic driver is the smarter choice for interior work, service calls, occupied spaces, and long runs of screws. Milwaukee states it runs 50% quieter than a standard impact driver, with smoother driving and 3X less vibration. The FLUID-DRIVE hydraulic powertrain reduces metal-on-metal contact inside the tool, which is why it feels different from a standard impact driver. You still get serious output, with up to 1000 in-lbs of torque and up to 3X faster application speed than the previous generation, but without the same sharp, rattling feel.
This kit is also practical from a system standpoint. It runs on the Milwaukee M18 battery platform and is compatible with all M18 batteries, so it fits right into an existing Milwaukee cordless setup. Milwaukee includes two M18 REDLITHIUM XC5.0 battery packs and an M18 and M12 multi-voltage charger, which gives you enough battery capacity to rotate through drilling and fastening tasks without immediately needing more packs. If you already own other M18 tools, that platform compatibility is a real advantage because you are buying tools, not starting over on batteries.
Milwaukee also adds jobsite-focused safety and control features where they count. The hammer drill includes AUTOSTOP control mode, which is designed to help prevent over-rotation in a bind-up. That is not fluff. On larger diameter drilling or aggressive bits, bind-ups are what twist wrists and shoulders. A feature like that is useful for anyone drilling overhead, in awkward positions, or through material where the bit can catch suddenly.
Who should buy this kit? Contractors, remodelers, electricians, plumbers, HVAC techs, maintenance crews, and serious DIY users who want a premium cordless combo without buying separate bare tools. If your work swings between drilling holes, setting anchors, driving structural screws, assembling hardware, and working in finished spaces where noise matters, this is a very smart pairing. If you only need a basic homeowner drill kit, it is more tool than you need. If you make your living with cordless tools, this is exactly the kind of combo that earns its spot in the truck.

Tool Nut’s Take
Tool Nut’s Take
Milwaukee M18 FUEL 2-Tool Combo Kit is the right kind of two-tool setup
This kit gives you one serious hammer drill and one driver that is easier to live with all day, which is a better combo than just getting two loud, hard-hitting tools that overlap each other.
- Who it’s for: Pros and serious DIY users who need a cordless combo kit for drilling, hammer drilling, and fastening across service work, remodels, and daily jobsite use.
- Why it stands out: The hammer drill brings top-end power and compact size, while the SURGE driver cuts noise and vibration without giving up useful fastening speed.
- Worth knowing: This is a premium M18 kit, and that is exactly who it is aimed at. If you already run M18 batteries, it fits right in. If you do not need this much performance, there are cheaper ways to get a drill and driver.
