There are promotions that take the edge off a purchase, and then there are promotions that genuinely change the value equation. Milwaukee Tool's latest M18 offer falls firmly into the second category. Through November 1, 2026, every qualifying M18 FUEL or M18 tool purchase at Ace Tool earns you a FREE Milwaukee M18 REDLITHIUM XC5.0 Battery at no additional cost. For any professional running the M18 platform, that is not a trinket. That is a battery you would have bought anyway, now coming to you free.
Twelve qualifying tools. One exceptional free reward. Here is the full breakdown.
The Free Good: Milwaukee M18 REDLITHIUM XC5.0 Battery (48-11-1850)

Before getting into the qualifying tools, it is worth spending a moment on what you are earning because this is not a standard pack-in battery.
The Milwaukee M18 REDLITHIUM XC5.0 Battery with 5.0Ah of capacity, powers high-demand tools through extended run cycles, handles the heat and stress of sustained use better than standard-capacity packs, and is backward and forward compatible with the entire M18 ecosystem. Whether you are running a circular saw through a full framing day or pushing a hammer drill through a concrete slab, the XC5.0 keeps up.
This battery, free, with any qualifying purchase. That is the deal.
Qualifying Milwaukee M18 FUEL and M18 Tools
Milwaukee M18 FUEL HACKZALL Item 2719-20

The M18 FUEL HACKZALL is the one-handed reciprocating saw that changed how professionals work in tight spaces. Compact enough to operate with a single hand, powerful enough to cut through conduit, copper pipe, PVC, drywall, and structural material without slowing down, the 2719-20 is the tool that electricians, plumbers, and remodelers reach for when a full-size recip saw simply does not fit the situation. The POWERSTATE brushless motor behind it drives a full stroke even under load, and the tool-free blade change keeps the job moving without interruption.
Milwaukee M18 FUEL 5" Random Orbital Sander Item 2837-20

Sanding has always been one of those tasks that demands patience and consistency. The M18 FUEL 5" Random Orbital Sander removes the variable of the cord and replaces it with a tool that delivers smooth, swirl-free finishes on cabinet faces, hardwood floors, furniture, and painted surfaces untethered, on your schedule, wherever the job is. The variable speed dial lets the operator match the tool to the material, and the POWERSTATE motor maintains that speed through the workpiece rather than fading under pressure.
For finish carpenters, cabinet makers, and painters who have been waiting for a cordless orbital sander worth trusting on their work, this is it.
Milwaukee M18 FUEL Multi Tool Item 2836-20

If there is one tool that earns a place in every trade bag on pure versatility, it is the oscillating multi tool and the M18 FUEL Multi Tool (2836-20) is the version worth owning. Cutting, sanding, scraping, and grout removal are all within reach of a single tool with the right accessory attached. The POWERSTATE brushless motor drives the oscillating head with consistent force that does not drop off mid-cut, and the ELBOW accessory system gives access to flush cuts and tight corners that defeat other multi tools on the market.
Remodelers, flooring contractors, plumbers, and electricians all find daily use for this tool.
Milwaukee M18 FUEL Compact Router Item 2723-20

The M18 FUEL Compact Router brings cordless freedom to finish woodworking applications that have historically demanded a corded tool. Edge profiling, dado cuts, template routing, and decorative detailing are all within reach without hunting for an outlet in the middle of a cabinet installation or millwork project. The router features variable speed control across a broad RPM range, giving the operator precise command over the cutting action across different bit types and wood species.
For finish carpenters and custom cabinet installers, the 2723-20 is a legitimate professional tool not a hobbyist compromise.
Milwaukee M18 FUEL 6-1/2" Circular Saw Item 2833-20

A circular saw is the heartbeat of a framing crew, and the M18 FUEL 6-1/2" Circular Saw (2833-20) earns its place at that level. With a POWERSTATE brushless motor capable of cutting through dimensional lumber at the speed and consistency tradespeople expect from their corded saws, the 2833-20 removes the last legitimate objection to going cordless on the cut line. The left-blade design gives right-handed operators a clean sightline to the cut mark, and the magnesium shoe keeps the tool light without sacrificing rigidity.
This is a premier entry point into Milwaukee's cordless cutting platform.
Milwaukee M18 FUEL PACKOUT 2.5 Gallon Wet/Dry Vac Item 0970-20

Job site cleanup is not glamorous, but leaving a site covered in dust and debris is not professional either. The M18 FUEL PACKOUT 2.5 Gallon Wet/Dry Vac (0970-20) integrates directly with Milwaukee's PACKOUT modular storage system, sits on top of a PACKOUT stack, and handles both wet and dry debris without the need for a separate corded shop vac. At 2.5 gallons, it is sized for working spaces rather than just post-job cleanups, and the M18 battery powering it is the same one powering every other tool on your belt.
For contractors who live inside the PACKOUT system, adding this vac to the stack with a free battery alongside it is a straightforward decision.
Milwaukee M18 REDLITHIUM FORGE XC8.0 Battery Item 48-59-1881

Sometimes the qualifying item itself is a battery and a serious one at that. The M18 REDLITHIUM FORGE XC8.0 Battery (48-59-1881) is Milwaukee's highest-capacity standard M18 pack, engineered with FORGE technology for superior heat management under the most demanding charge and discharge conditions. High-draw tools like the rotary hammer, circular saw, and compact bandsaw unlock their full runtime potential with the XC8.0 behind them.
Purchasing the FORGE XC8.0 and receiving the XC5.0 free means walking away with a Milwaukee battery capacity in a single transaction. For a crew running multiple tools across a long day, that is a meaningful addition.
Milwaukee M18 PACKOUT Six Bay Rapid Charger Item 48-59-1809

Downtime waiting for batteries to charge is lost productivity. The M18 PACKOUT Six Bay Rapid Charger (48-59-1809) eliminates that bottleneck by charging up to six M18 batteries simultaneously, integrating directly into the PACKOUT storage system for a clean, organized charging station on any job site or in any service vehicle. For crews running multiple M18 tools across multiple operators, this charger is not a convenience, it is a logistics solution.
The Six Bay Rapid Charger pairs naturally with the free XC5.0 battery that comes alongside it, giving you both the charging infrastructure and the additional pack needed to keep your fleet running.
Milwaukee M18 FUEL ½" Hammer Drill/Driver Item 2904-20

The M18 FUEL ½" Hammer Drill/Driver (2904-20) is the benchmark against which every other cordless hammer drill is measured. With four modes of operation drill, drive, hammer drill, and DRIVE CONTROL the 2904-20 handles anchor drilling into masonry and concrete alongside precision fastening in wood and metal without ever asking the operator to switch tools. The all-metal chuck grips bits securely under impact, and the POWERSTATE motor delivers the torque to back up the spec sheet in real working conditions.
This is the hammer drill that professionals who have used both know is the right choice.
Milwaukee M18 FUEL ½" Drill/Driver Item 2903-20

Not every drilling application demands hammer mode, and the M18 FUEL ½" Drill/Driver (2903-20) is the refined, lighter companion to the hammer drill for woodworking, cabinetry, electrical, and general construction fastening. It is the most accessible drill in this promotion, and the POWERSTATE motor inside it still outperforms most competitors regardless of the lower price point. For professionals who already own a hammer drill and need a dedicated drill for their rotation, the 2903-20 is the logical next acquisition especially when a free battery is coming with it.
Milwaukee M18 FUEL 2-Piece Combo Kit HD/ID Item 3697-22

If you are building out an M18 kit from scratch or equipping a new crew member, the M18 FUEL 2-Piece Combo Kit (3697-22) is the most efficient starting point in this promotion. Combining the M18 FUEL ½" Hammer Drill/Driver and the M18 FUEL ¼" Hex Impact Driver in a single kit with two batteries and a charger, the 3697-22 delivers everything needed to get to work on day one. Both tools represent the top tier of Milwaukee's M18 FUEL lineup in their respective categories, and they arrive together in a durable carrying case ready for the job site.
A free XC5.0 battery included, this kit represents one of the strongest overall values in the promotion for any professional looking to expand or establish their cordless platform.
Milwaukee M18 Compact Brushless 4-Piece Combo Kit Item 3693-24CX

For the professional who wants to do it all in one purchase, the M18 Compact Brushless 4-Piece Combo Kit (3693-24CX) is the answer. This kit bundles four of the most commonly reached-for cordless tools in a single package engineered for compact form factors that navigate tight spaces without sacrificing the brushless performance that M18 professionals expect. Four tools, batteries, a charger, and a bag. Everything you need to show up and work, organized and ready.
A free XC5.0 battery, the 3693-24CX is the most comprehensive single investment available in this promotion and a compelling proposition for any contractor equipping a new technician or rounding out a growing fleet.

Ace Tool is not a general merchandise retailer that happens to carry power tools. It is a professional tool destination built around the trades, staffed by people who understand the products, and stocked with the full range of Milwaukee's M18 lineup rather than a curated handful of popular items.
When a promotion of this caliber comes along, the difference between retailers becomes clear. At Ace Tool, every qualifying item listed above is available, the pricing is accurate and IMAP-compliant, and the team can help you identify which tool or kit best fits your specific application rather than pointing you toward whatever is easiest to sell.
Whether you are an electrician adding to a platform you have trusted for years or a contractor equipping a crew with a complete Milwaukee system, Ace Tool is the right place to make that investment.
Shop Ace Tool before November 1, 2026, choose your qualifying Milwaukee M18 FUEL tool, and walk away with a FREE M18 REDLITHIUM XC5.0 Battery
