A milwaukee drill and impact driver set pairs two tools that handle different jobs on the same battery platform, so you can drill precise holes and drive long fasteners without swapping packs. This guide walks through how to decide whether a combo kit fits your work, how to match voltage and tool size to your projects, what to check in the kit contents, and how to avoid the mistakes that cost people time and screws. By the end, you should be able to pick a set with confidence and get the most from it.
Why Pair a Drill With an Impact Driver?
A drill and an impact driver look similar, but they work differently. A drill driver uses a three-jaw chuck, lets you set torque with a clutch, and is the better choice for drilling holes, driving screws where you need control, and working with a wide range of bits. An impact driver uses a hex collet that accepts 1/4-inch hex bits, delivers rotational bursts called impacts, and drives fasteners quickly with far less effort on your wrist. Our explainer Drill vs Impact Driver: Which Do You Need? covers the differences in more depth.

Owning both lets you use each tool for what it does best. Most framing, decking and cabinet work involves drilling pilot holes and then driving screws, and switching between the two is faster than changing bits and clutch settings on one tool.
Step 1: Decide Which Battery Platform You Need
Milwaukee sells two main cordless platforms: M18 for heavier-duty work and M12 for compact, lighter tasks. Choosing one platform before you buy matters because batteries and chargers are not interchangeable between them.
- M18 sets suit framing, decking, concrete anchors, and frequent all-day use. They are heavier but deliver more torque and runtime.
- M12 sets suit cabinet installation, electrical work, furniture assembly and overhead tasks where weight and size matter more than raw power.
If you already own Milwaukee batteries, buying a bare-tool combo (tools without batteries) can save you from paying for duplicate packs. Check the battery amp-hour rating too. Higher amp-hour packs run longer but weigh more.
Step 2: Match the Tools to Your Work
Think about the fasteners and materials you use most. A few guidelines:
- For drilling in wood and metal, a drill with a 1/2-inch chuck handles most bits, including larger spade and hole saw bits.
- For driving structural screws, lag bolts and long deck screws, the impact driver does the heavy lifting.
- For masonry and concrete, look for a hammer-drill function on the drill, or plan to use a separate hammer drill. Our article on Milwaukee Cordless Drill Hammer: How to Choose and Use One Right explains the setting.
Step 3: Check What Is in the Kit
Kits differ in what they include, so read the contents list carefully. Look for:
- Number of batteries (two is common; one can leave you waiting)
- Charger type and whether it is rapid or standard
- Carrying case or bag
- Included bits and drivers (usually a starter set, not a full set)
Manufacturers specify different runtimes and torque figures for each tool model, so compare the specific model numbers in the kit rather than the set name alone.
Step 4: Compare Key Specs Before Buying
Use this table to check the specs that most affect performance:
| Spec | What it means | What to look for |
|---|---|---|
| Voltage platform | Battery system and compatibility | M18 for heavy work, M12 for compact tasks |
| Chuck size (drill) | Largest bit shank the drill accepts | 1/2-inch for most drilling |
| Max torque (drill) | Turning force, listed as inch-pounds | Higher for driving large fasteners |
| Driver output (impact) | Rotational force from impacts | Higher for lag bolts and structural screws |
| Amp-hour rating | Battery capacity | Higher for longer runtime |
| Brushless motor | Motor type with longer life and better efficiency | Preferred for regular use |
Step 5: Set Up Your First Use
When the set arrives, charge both batteries fully before you start. Then follow these steps:
- Insert a fresh battery into the drill and set the clutch to a low number for screws.
- Choose the correct bit. Use impact-rated bits in the impact driver.
- Drive a test screw in scrap wood to confirm depth and speed.
- Repeat with the impact driver, starting at low speed to see how it grabs the fastener.

Common Mistakes
- Using standard bits in the impact driver. Standard bits can shatter under impact. Use bits labeled impact-rated. The guide Impact-Rated vs Standard Driver Bits explains the difference.
- Buying the wrong voltage. M12 and M18 batteries do not interchange, so a mismatched kit leaves you with unusable packs.
- Skipping pilot holes. Driving long screws into hardwood without a pilot hole invites splitting and stripped heads.
- Ignoring the clutch. Leaving the drill on a high clutch setting strips screw heads and cams out.
- Overlooking spare batteries. A single pack runs out mid-job, so keep at least two charged.
Tips for Getting More From Your Set
- Keep both batteries rotating so one is always charging.
- Store bits in a dedicated holder to keep impact-rated bits separate.
- Use a depth stop when driving repetitive screws, as covered in Driver Bits: Impact-Rated Bits, Bit Holders and Depth Stops.
- If you also work with a circular saw, check Milwaukee M18 Circular Saw Fuel Review: Features and Performance to see whether it shares your battery platform.
Recommended gear

FAQ
Can I use Milwaukee M12 and M18 batteries interchangeably?
No. M12 and M18 packs are designed for their own platforms and do not fit each other’s tools.
Does a milwaukee impact drill driver set come with bits?
Most kits include a basic bit set, but it is usually a starter selection. Plan to buy impact-rated bits separately for regular use.
Which tool should I use for driving screws?
Use the impact driver for long fasteners and structural screws, and the drill for work that needs clutch control or pilot holes.
Can the drill drill into concrete?
Only if it has a hammer-drill setting and you use masonry bits. Standard drilling into concrete will wear bits quickly.
Are brushless motors worth it?
Owners often report longer runtime and less maintenance with brushless motors, which is why they suit frequent use.
How many batteries should I buy?
Two is a practical minimum for most jobs, so one can charge while the other is in use.
Do I need a special charger?
Use the charger that comes with your kit or one rated for your battery platform. Mixing chargers across platforms is not supported.
Is an impact driver safe for all screws?
It suits most driving tasks, but very small or delicate fasteners can be overdriven. Lower the speed and check the depth frequently. For electrical or structural code questions, consult a licensed professional.
Conclusion
A milwaukee drill and impact driver set gives you two complementary tools on one battery platform. Choose M18 for heavy work or M12 for compact tasks, check the kit contents, and match bits and settings to your materials. Avoid the common mistakes around bit selection and clutch use, and your set will handle most home and job-site tasks well.
