Key Takeaways
- The Milwaukee® 2904-20 and 2904-22 are the same Gen 4 M18 FUEL™ hammer drill. Both deliver 1,400 in-lbs of torque, 2,100 max RPM, 33,000 BPM, and a 1/2" all-metal chuck, so the drilling experience is identical between them.
- The only thing that changes is what comes in the box. The 2904-20 ships as the bare tool, while the 2904-22 adds two M18™ REDLITHIUM™ XC5.0 batteries, a multi-voltage charger, and a blow-molded hard case.
- Existing M18™ owners save the most with the 2904-20 bare tool, while first-time buyers and crews building out the platform get better dollar-per-component value from the full 2904-22 kit than buying batteries and chargers separately.
- GenuineTools lists the 2904-20 at $132.99 (56% off MSRP) and the 2904-22 at $239.99 (27% off MSRP), a $107 spread that maps cleanly to the included batteries, charger, and case.
What Separates the 2904-20 from the 2904-22
The Milwaukee® 2904-20 and 2904-22 are the same Gen 4 M18 FUEL™ hammer drill packaged differently. The 2904-20 is the bare tool at $132.99 on GenuineTools, while the 2904-22 is the full kit at $239.99, a $107 gap that buys you two M18™ REDLITHIUM™ XC5.0 batteries, a multi-voltage charger, side handle, and blow-molded hard case. Performance is identical on both: 1,400 in-lbs of torque, 2,100 max RPM, 33,000 BPM, and a 1/2" all-metal chuck. Which one fits depends on whether you already own M18™ batteries.
If you already run M18™ batteries, the 2904-20 is the obvious pick. If you're new to the platform or replacing an aging battery setup, the 2904-22 kit is the better value. Below, we break down what's inside each box, the exact price gap at GenuineTools versus MSRP, the specs both versions share, and which configuration fits which buyer.

Milwaukee 2904-20: Bare Tool Configuration
The Milwaukee 2904-20 is the bare-tool version of the Gen 4 M18 FUEL™ Hammer Drill/Driver. It ships in retail packaging with the drill itself, a belt clip, and the standard side handle: no battery, no charger, no case. At GenuineTools, this configuration is priced at $132.99, marked down from a $299.00 MSRP.
This SKU is built for tradespeople who already run the M18™ platform. Pulling a battery from your existing kit means you skip the cost of duplicates and only pay for the tool itself.
The 2904-20 is also a popular choice for fleet expansion, since contractors managing multiple crews often buy bare tools and standardize batteries across the jobsite. With more than 275 compatible M18™ tools currently in the lineup, the bare-tool route compounds savings as your tool count grows.
The Milwaukee 2904-20 bare-tool hammer drill is ideal for tradespeople already on the M18 platform, letting you skip the cost of duplicate batteries and chargers while still getting full Gen 4 FUEL performance.
Milwaukee 2904-22: Complete Kit Configuration
The Milwaukee 2904-22 is the same drill, packaged with everything needed to start drilling out of the box. The kit includes the M18 FUEL™ Hammer Drill/Driver, two M18™ REDLITHIUM™ XC5.0 battery packs, an M18™ & M12™ multi-voltage charger, a side handle, and a blow-molded carrying case. GenuineTools currently lists the kit at $239.99, down from $329.00 MSRP.
For first-time M18™ owners, the 2904-22 eliminates the headache of sourcing compatible batteries separately. Two 5.0 Ah packs deliver enough runtime to push through extended drilling sessions in dense materials, and Milwaukee® rates this combination as the longest-running configuration in its class. The hard case keeps the kit organized between jobs and protects the drill during transport; an underrated value-add when comparing kit pricing against a la carte components.
The Milwaukee 2904-22 kit includes the Gen 4 FUEL hammer drill, two XC5.0 batteries, a multi-voltage charger, and a hard case, making it the ready-to-run option for first-time M18 buyers.
Shared Performance Specs at a Glance
Because the 2904-20 and 2904-22 contain the same physical drill, every performance spec is identical. Both deliver 1,400 in-lbs of peak torque, 0-500/0-2,100 RPM in two speed ranges, and 33,000 BPM in hammer mode. The drill measures only 6.9 inches in length and weighs 3.3 lbs without a battery, making it the most compact tool in its class.
Both versions share the POWERSTATE™ brushless motor, REDLINK PLUS™ Intelligence, AutoStop™ Control Mode, the 1/2-inch all-metal ratcheting chuck with carbide teeth, the 16-position mechanical clutch, and the onboard LED work light. Pick either one and the drilling experience is the same.
Price Comparison: 2904-20 vs 2904-22 at GenuineTools
The headline price gap between the two SKUs is $107.00 at GenuineTools, with the 2904-20 at $132.99 and the 2904-22 at $239.99. That spread is what you're effectively paying for: two 5.0 Ah batteries, a multi-voltage charger, and a hard case. Looking at standalone retail pricing on a Milwaukee® 5.0 Ah XC battery and a multi-voltage charger, the math on the kit upgrade pencils out favourably for buyers who don't already own batteries.
GenuineTools' pricing also represents a meaningful drop from MSRP: 56% off on the 2904-20 and 27% off on the 2904-22.
Key Differences Between the 2904-20 and 2904-22
The differences boil down to four areas: included batteries, charger, carrying case, and weight of the tool. The 2904-20 ships without a battery or charger; you supply both. The 2904-22 includes two M18™ REDLITHIUM™ XC5.0 battery packs (model 48-11-1850) and a multi-voltage charger (48-59-1812) that handles both M18™ and M12™ batteries.
The 2904-22 also includes a blow-molded hard case for storage and transport, while the 2904-20 ships in standard retail packaging without a case. Operating weight differs because of the battery: the bare drill weighs 3.3 lbs, but mounting a 5.0 Ah XC pack and the total weight climbs to 4.91 lbs.

Which Configuration Fits You Best?
Pick the 2904-20 if you already own M18™ batteries and a charger. The $107 you save covers the cost of an extra battery for your existing setup, or simply pads your budget for a different tool. Bare-tool pricing also tends to scale better when expanding a fleet, since you avoid paying for batteries you don't need.
Choose the 2904-22 if you're new to the M18™ platform, replacing aging batteries, or want a turnkey kit with a case included. The two 5.0 Ah XC batteries provide all-day runtime for serious drilling, and the multi-voltage charger doubles as a long-term accessory for any future M18™ or M12™ tool you add. For DIYers and contractors making a single Milwaukee® purchase, the kit nearly always delivers more value than buying components separately.
The Bottom Line on the 2904-20 vs the 2904-22 at GenuineTools
The 2904-20 and 2904-22 share the same Gen 4 M18 FUEL™ drill, so the decision rests on what you already own. Existing M18™ users save the most with the bare tool at $132.99, while first-time buyers and contractors building out a new platform get the better dollar-per-component value from the $239.99 kit.

Frequently Asked Questions (FAQs)
Is the Milwaukee 2904-20 the same drill as the 2904-22?

Can I use my existing M18™ batteries with the 2904-20?
Yes. The 2904-20 is compatible with all M18™ batteries and chargers, meaning any M18™ REDLITHIUM™ pack across the CP, XC, HIGH OUTPUT, and FORGE lines will work. Compatibility across the full M18™ family is one reason the bare-tool option appeals to existing platform owners.
