Short answer: a Milwaukee combo kit is usually the better value when you need most of its included tools and do not already own compatible M18 batteries and a charger. A tool-only purchase is usually the smarter buy when you already have an M18 power system or need just one specific tool. The deciding test is not the number printed on the box. Compare the exact tools you will use, the battery capacity and count, the charger, and current prices for the same region and date.
There is no reliable universal savings percentage for combo kits. Milwaukee sells kits with different tool lineups and battery packages, and retailer prices change. Treat each purchase as a same-basket calculation rather than assuming that a larger tool count automatically means a lower cost.

What “tool-only” and “combo kit” mean
Tool-only (bare-tool) purchases
A tool-only listing contains the power tool but normally excludes batteries and a charger. It is intended for someone who already owns a compatible battery platform. Before buying, confirm that the tool uses the same Milwaukee platform and voltage as your packs. An M18 battery does not become interchangeable with every Milwaukee product simply because the brand name matches.
The main financial advantage is avoiding duplicate equipment. If your workshop already has several usable M18 packs and a charger, buying another drill, saw or grinder without a battery can keep the purchase focused on the capability you lack. You also avoid paying for kit tools that would remain in a case.

Battery combo kits
A combo kit groups several tools with one or more batteries, a charger and, often, a case or bag. The bundle is intended to establish or expand a complete system in one transaction. Contents are model-specific: a four-tool kit and a five-tool kit may contain different tool types, battery capacities and chargers even when both are described as M18 packages.
For a new M18 buyer, the battery and charger can be as important as the tools. For an existing owner, those same items may have little incremental value if they duplicate equipment already on the bench.
The starting point that changes the answer
You are new to the M18 system
A kit often has the strongest case when you need several of its included tools and have no compatible batteries or charger. Buying each bare tool would require adding packs and a charger, so the relevant comparison is not kit price versus bare-tool price. It is kit price versus the complete cost of the same tools, the required batteries and a charger.

Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →That does not make every kit a bargain. Remove any tool you would not use from your personal valuation. A nominal five-tool package can be worse value than a smaller kit if the extra tools duplicate equipment you own or do work you never perform.
You already own M18 batteries and a charger
Start with the bare-tool price. A kit can still win if its additional price is lower than the value of batteries or other contents you genuinely need, but do not count duplicate packs and chargers as full savings. They are only useful value if you would otherwise buy them, need more capacity, or have a clear second-workstation use.
You need one particular tool
Compare the exact model in tool-only and kit listings. A kit with several unwanted tools adds cost, storage and resale work. A lower tool count is not automatically inferior value; paying only for the capability you need can produce the lowest total cost.

You need a higher-tier model
Check the model number and product tier, not just the tool category. An M18 FUEL drill and a standard M18 drill are not interchangeable line items for a price comparison. A cheaper kit that contains a different model may not satisfy the performance, control or durability requirements of your work.

The following examples show why the exact listing matters. They are not a universal catalog of every Milwaukee package, and contents can differ by retailer, region and bundle variant.
| Listing | What is established | Battery and charger information | Value implication |
|---|---|---|---|
| M18 FUEL 2-Tool Combo Kit, model 3697-22 | Acme Tools describes an M18 FUEL hammer drill and an impact driver, supplied as a two-tool package. | Two XC5.0 batteries, an M18/M12 multi-voltage charger and a case are described in the listing. | Attractive to a buyer who needs both fastening tools and has no M18 charging setup; less compelling if those batteries and charger are already owned. |
| M18 FUEL 5-Tool Combo Kit, model 3697-25 | Milwaukee’s official listing identifies a five-tool M18 FUEL configuration. The exact tool lineup should be checked on the live listing before purchase. | The official listing specifies two XC5.0 batteries and enumerates the charger and other kit contents. | Do not compare it with a four-tool package by count alone. Match each included model to jobs you actually have. |
| M18 Cordless Lithium-Ion 4-Tool Combo Kit, model 2696-24 | Milwaukee provides this as a different M18 four-tool configuration. An official M18 four-tool example lists a drill, reciprocating saw, impact driver and work light; verify the exact contents attached to model 2696-24. | Use the model’s current listing to confirm pack count, amp-hour ratings and charger. | Its documented warranty terms are model-specific: a five-year limited tool warranty and a three-year limited battery warranty. |
The table illustrates two common mistakes. First, “four-tool” and “five-tool” labels do not identify the same capabilities. Second, battery count alone is incomplete: two packs can have different amp-hour capacities, and a charger you already own changes the value of a new bundle.
Run a same-basket price comparison
Use prices from the same country, retailer type and time window. A sale price on a kit and a regular price on bare tools can produce a misleading result, as can comparing a bundle variant with the base model.
- Write down the exact tools. Record each model number, not just “drill” or “saw.” Include the tier, such as FUEL, and note whether the kit contains a hammer drill, impact driver, reciprocating saw, grinder, light or another tool.
- Mark the tools you will use. Assign a yes/no decision to every included item. Do not give unwanted tools their full standalone retail price in your personal calculation.
- Record the battery setup. Note platform, number of packs and each pack’s amp-hour rating. The 3697-22 and 3697-25 listings, for example, specify two XC5.0 batteries; another listing may not.
- Account for the charger once. If you own a compatible charger, enter its value as zero in the new-purchase basket. If you do not, add the price of a charger suitable for the batteries you are buying. The 3697-22 description includes an M18/M12 multi-voltage charger.
- Use live prices for every line item. Compare the kit with the sum of the exact bare tools, the batteries needed for your work and the charger needed to operate them.
- Separate temporary promotions. Record whether a displayed price is a sale, a bundle-only offer or a regular listing. A promotion should not be treated as a permanent list price.
- Check availability and returns. A lower price has little value if the listing is unavailable in your region, has different contents or carries return conditions that do not suit your purchase.
The calculation is simple:
complete bare-tool basket = useful bare tools + batteries needed + charger needed

A positive result means the kit costs less than assembling the same useful system at the prices you recorded. A negative result means the bare-tool route is cheaper. This is a price comparison, not proof that one route is better for every buyer: battery inventory, tool usefulness and warranty terms still matter.
How to value batteries and chargers
Battery capacity is part of the product
Two batteries are not necessarily equivalent to two batteries in another listing. Confirm amp-hour capacity and chemistry in the exact package. Higher-capacity packs can provide more stored energy for demanding work, but they may also add weight and cost. A compact pack can be preferable for overhead or detail work, while a larger pack may be more useful for extended cutting or drilling. Choose based on the jobs you expect, not only the number of packs in the photograph.
A duplicate charger is not automatic savings
When you already have a compatible charger, its inclusion in a kit may have little personal value. A first-time buyer should include a charger in the bare-tool basket because tools cannot be used productively without a way to recharge the packs. Confirm charger compatibility rather than assuming that every Milwaukee charger serves every battery family; the 3697-22 listing specifically describes an M18/M12 multi-voltage charger.
Consider how many tools may be used at once
A single battery can move between tools, but switching may interrupt work. If you regularly drill, cut and drive in the same project, a second pack can have practical value even when the nominal price comparison is close. Conversely, if one tool is used occasionally, buying several packs to obtain a kit may tie up money in equipment that sits unused.
Do not let tool count hide the real lineup
Manufacturers and retailers use tool counts as shorthand, but the count does not tell you whether the package fits your work. A light may be useful on a job site but have little value to someone who already owns task lighting. A reciprocating saw can be central to renovation work and irrelevant to a cabinetmaker. An impact driver and hammer drill may be complementary for one buyer and redundant for another who needs a grinder or saw instead.
Open the contents list and make a personal “must use,” “nice to have” and “will not use” column. The kit’s value should be based primarily on the first column. Treat the second as optional value and the third as a cost, storage burden or item you would need to sell.

When the combo kit is the better choice
- You are building an M18 system from zero and need both batteries and a charger.
- Most of the included tools match work planned in the near term.
- The kit supplies battery capacities appropriate to those tools, rather than packs too small for your workload.
- The complete bare-tool basket costs more at current, same-region prices.
- You can use the included charger and do not already have several compatible packs.
- The exact models meet your required tier and features.
For example, the 3697-22 package makes sense for a new M18 buyer who specifically needs a hammer drill and impact driver, wants two XC5.0 batteries, and needs the included multi-voltage charger. It is not automatically the best choice for someone seeking only a drill or who already owns the same battery setup.
When tool-only is the better choice
- You already own compatible M18 batteries and a charger in good working order.
- You need one tool rather than a set of unrelated capabilities.
- The kit contains a lower-tier or different model than the one your work requires.
- You would have to store, resell or give away several unwanted tools.
- Your existing batteries match the task better than the packs supplied in the kit.
- The bare tool is available at a lower current price after accounting for no new battery or charger.
Buying bare does not mean rejecting kits permanently. If your battery inventory later becomes inadequate, price a battery-and-charger purchase separately and compare it with any current bundle. The right choice can change when your tool collection or project mix changes.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Understand the $619 price snapshot correctly
A Home Depot page reviewed for a 3697-22-related bundle showed $619. That displayed amount applied to a bundle variant that also included a grinder. It is a retailer snapshot, not a stable list price for every version of model 3697-22 and not evidence that all Milwaukee combo kits cost less than separate purchases.
Use a displayed price only after confirming the product title, model number, included grinder or other extra tool, battery package, region and date. If any of those differ from the kit you are evaluating, enter the listing as a separate basket rather than treating it as the base kit’s price.
Warranty and model-specific terms
Warranty coverage should be checked against the exact model and included battery. Milwaukee’s official listing for model 2696-24 states a five-year limited tool warranty and a three-year limited battery warranty. Those terms should not be generalized to every M18 kit, every battery or every retailer bundle. Save the product page and receipt, and read exclusions, registration requirements and service procedures that apply to your purchase.

Common comparison mistakes and how to avoid them
Comparing different tools
A five-tool kit may include a light where another package includes a grinder. Count only tools that perform the jobs you need, and match model numbers before calculating.
Counting duplicate equipment at retail value
If you already own batteries and a charger, adding their shelf price to the value column exaggerates the kit’s benefit. Use the replacement cost only when you would actually buy those items now.
Ignoring battery capacity
Two low-capacity packs and two XC5.0 packs are not the same purchase. Record amp-hour ratings and consider tool weight, expected runtime and charging frequency for your work.

Assuming every listing has the same contents
Retailer bundle names can resemble official model names while adding or removing a tool. Read the contents section, verify the model number and inspect what is in the case.
Using a kit to obtain one expensive tool
If one tool is the only reason you are considering a bundle, compare its bare-tool listing first. Include the resale or disposal cost of every unwanted item before calling the kit a saving.
A practical decision checklist
- List the jobs and tools you need during the next year.
- Circle the exact models and tiers that satisfy those jobs.
- Inventory your M18 batteries, amp-hour ratings and chargers.
- Choose the minimum battery capacity and count that your work requires.
- Price the exact bare tools, needed batteries and charger on the same date.
- Price the exact combo kit, including any retailer-specific bundle additions.
- Remove unwanted tools from your personal value calculation.
- Check warranty terms, return policy and regional availability for the exact model.
- Buy the kit only when its useful contents and complete-system price beat the bare-tool basket for your situation.
Bottom line for the main Milwaukee examples
Choose a combo kit when you need several listed tools and are also buying into the M18 battery system. The M18 FUEL 3697-22 is a clear example of a two-tool package whose two XC5.0 batteries, multi-voltage charger and case matter to a new owner. Choose tool-only when your M18 batteries and charger are already covered or when one specific tool is all you need. For any five-tool or four-tool package, verify the exact lineup and battery details first; the model number and current listing matter more than the tool count printed in a headline.
