Cons
- Modest Improvements Over Gen 2: When testing the tool head-to-head against older units, Evan from Tool Show observed only minor speed and smoothness gains, concluding that existing Gen 2 owners do not necessarily need to rush out for an upgrade.
- No Electronic Anti-Kickback: Clint from Pro Tool Reviews noted that this Gen 3 hammer drill does not include the newer Auto-Stop safety feature found on later generations, meaning users must maintain a firm two-handed grip when drilling with large hole saws.
- Bare Tool Availability: Because Milwaukee has released newer iterations, reviewers mentioned that finding this specific Gen 3 model brand-new outside of bundled kits can occasionally take some searching.
Where They Disagree
The primary debate among testers involves whether the 2804-20 model is the sweet spot in Milwaukee’s drill lineup or an intermediate step worth skipping. The collective testers at Tool Show advised that anyone already equipped with a Gen 2 drill should hold off on upgrading unless buying a full combination tool kit, arguing that the real-world performance jump is simply too subtle. On the other hand, the youtuber at 4thewin praised the Gen 3 as a top-tier powerhouse, showing that its thermal management, raw output, and refined balance make it an outstanding standalone investment.
Additionally, Clint from Pro Tool Reviews demonstrated that while the newer Gen 4 drill delivers higher measured torque and added kickback protection, the Gen 3 model actually matched or outperformed it in several real-world speed drills. For tradespeople who prioritize rapid drilling speeds over automated safety stops, many reviewers agree this 2804-20 model remains an exceptionally capable workhorse on the jobsite.

Milwaukee 2804-20 Chuck Replacement
The 2804-20 features a heavy-duty, all-metal 1/2-inch ratcheting chuck designed for maximum bite. However, prolonged hammer drilling in concrete eventually causes wear on the internal jaws. When slippage occurs, replacing the assembly restores total factory holding force quickly.
- First step: Open the chuck jaws fully to access the internal retaining screw.
- Reverse threads: Turn the internal chuck screw clockwise using a T20 or T25 Torx driver.
- Break it loose: Secure a large hex wrench inside the jaws. Tap it hard counter-clockwise with a mallet.
- Install the new unit: Thread on the replacement chuck, tighten securely, and lock down your reverse retaining screw.
Keeping an efficient chuck guarantees uninterrupted power transmission. You can secure a pristine Milwaukee M18 Fuel hammer drill assembly to ensure your jobsite tasks never stall unexpectedly.
Real-World Jobsite Power And Speed
Field professionals praise this hammer drill for its balance of raw torque and exceptional working cadence. The brushless motor pumps out reliable power without bogging down in wet framing lumber. Consequently, tradespeople finish boring holes through dense structural timbers rapidly.
Furthermore, the built-in hammer mechanism chisels into masonry cleanly. In side-by-side videos, evaluators pushed large spade bits and hole saws without triggering overload protection. The robust internal gearing maintains high rotational velocity even under brutal loads.
- Masonry drilling: Rapid impact rate punches clean anchor holes in poured concrete effortlessly.
- Framing operations: Drives large lag bolts straight home without stalling out midway.
- Sustained output: Advanced internal circuitry protects against overheating during all-day commercial tasks.

FAQ
Is the Milwaukee 2904-20 actually a hammer drill?
Yes, the 2904-20 is Milwaukee’s Gen 4 M18 FUEL hammer drill/driver. It features a dedicated hammer selector that delivers high-frequency percussion alongside rotation to bore holes into brick, block, and concrete. If you want blistering speed at a competitive value, its Gen 3 sibling, the Milwaukee M18 Fuel hammer drill, offers a virtually identical punch in the field.
Can standard Milwaukee drills work as hammer drills?
No, standard Milwaukee drill/drivers only rotate; they do not have the internal percussion mechanism required for hammer drilling. To drive bits into masonry or poured concrete, you must select a tool equipped with a hammer mode collar. Choosing a dedicated workhorse like the Milwaukee M18 Fuel hammer drill/driver ensures you can switch between standard drilling, fastener driving, and hammer modes with a simple click.
Which hammer drill is Milwaukee’s best overall?
Milwaukee’s flagship M18 FUEL models consistently rank as their best hammer drills. Professional testers from multiple tool channels agree that the brushless Gen 3 and Gen 4 lines lead the industry thanks to their massive torque output, all-metal chucks, and smart overload protection.
