Makita GPH03 40V Max XGT Hammer Drill
Released in March 2026, the GPH03 is Makita's most powerful hammer driver-drill, putting out 1,590 in-lbs of max torque - more than most corded drills and every cordless flagship rival. It pairs a 3-speed transmission (0-650/1,800/2,400 RPM, up to 36,000 IPM) with a 92-setting electronic digital clutch and Active Feedback-sensing Technology (AFT) anti-kickback. Pro Tool Reviews scored it 9.5/10, confirming it out-torqued the GPH01 in lag-bolt driving.
Specifications
Features
Pros
- ✓Class-leading 1,590 in-lbs of max torque makes it the most powerful cordless hammer driver-drill on the market, out-muscling every 18V/20V flagship.
- ✓Pro Tool Reviews' testing showed it drives lag bolts deeper than the already-strong GPH01, rating it 9.5/10 for pros who need maximum power.
- ✓The true 3-speed transmission adds an 1,800 RPM middle gear that reviewers say hits the working sweet spot 2-speed drills constantly miss.
- ✓Makita says medium gear delivers twice the working speed of previous 2-speed models without overloading the battery.
- ✓The 92-setting electronic digital clutch remembers a separate torque setting per speed, giving unusually precise fastening control.
- ✓Active Feedback-sensing Technology (AFT) shuts the motor off quickly when the bit suddenly binds, which testers found effective at protecting wrists.
- ✓XPT dust and water resistance plus rubber overmold and bumpers are built for jobsite abuse.
- ✓Reviewers praise the redesigned side handle and overall ergonomics despite the tool's size, and 40V XGT batteries sustain corded-class output under load.
Cons
- ✗Premium pricing at $259 bare and $399 for a single-battery 4.0Ah kit - noticeably more than street prices on DeWalt's and Milwaukee's flagships.
- ✗Bulkier and heavier than other XGT drills at 7.75 in long and 4.1 lbs bare; reviewers flag the size as the main tradeoff for the torque.
- ✗At 6.2 lbs with battery, extended overhead work causes fatigue faster than 18V-class drills.
- ✗The older GPH01 actually beat it in four of five speed-based drilling tests - the GPH03 trades outright speed for torque.
- ✗Top speed of 2,400 RPM is down from the GPH01's 2,600 RPM, so small-bit drilling is slightly slower.
- ✗Buying into the 40V XGT platform is expensive, and XGT batteries do not interchange with Makita's 18V LXT tools.
- ✗Released March 2026, so there is little long-term reliability data and almost no retailer review history yet.
- ✗Rated masonry capacity is 13/16 in - it is still a hammer drill, not a replacement for an SDS rotary hammer on big concrete jobs.
