Makita’s XGT tools get most of their attention for raw numbers: torque, rpm, and bpm. But the real story is in the motor control system that manages how that power is delivered. The newest generation, including the GPH03 hammer drill and GDT04 impact driver, uses a redesigned controller that makes the tools feel smoother, stronger, and more predictable under load.
Makita’s latest XGT drill and impact driver combo kit represents a meaningful refinement of the 40-volt platform. While the headline numbers are impressive (1,590 inch pounds of torque for the drill and 2,040 inch pounds for the impact driver), the real improvements show up in how these tools feel during daily carpentry work.
The GPH03 hammer drill is noticeably smoother than the previous GPH01. Makita reworked the motor control to deliver a more progressive soft start, which makes a difference when starting large augers, self-feed bits, or hole saws. The drill holds rpm longer under load and recovers faster when it hits knots or dense grain than its predecessor. Heat management is also improved; the tool maintains consistent power during long boring sessions instead of tapering off. It should be noted that all this torque comes with a sacrifice in speed; even with a 3-speed gear box the GPH03 is 200 rpms slower than the GPH01.

Makita’s GPH03 hammer drill (left) and GDT04 impact drill/driver (right) are optimized for heavy-duty work, especially when paired to 4.0Ah and 5.0Ah batteries. This extra torque and speed may not be necessary for all users, but for heavy work this pair meets real jobsite demands.
The GDT04 impact driver is ½ inch longer than its predecessor the GDT01. While this may seem like a negative to some, I believe this is an improvement. That ½ inch moves the collet out farther from the base and keeps the battery from getting in the way with shorter bits. But its speed is what stands out. With 4,400 rpms and refined assist modes, the driver starts screws cleaner and reduces cam-out—especially useful with structural screws and for decking and metal roofing work. The updated controller also keeps the tool cooler during repetitive fastening, which helps maintain speed throughout the day.

Taken together, the GPH03 and GDT04 make it seem like Makita finally tuned XGT for real jobsite demands. They’re smoother, stronger, and more predictable than the previous generation, and they make a compelling case for carpenters who need high-torque cordless tools that don’t get beaten up in the process. The downside to all this control and power is that both tools are slightly bigger and heavier than the previous generation. If you are already on the XGT 40-volt platform and need more torque for long structural fasteners or for boring large holes on a regular basis, then upgrading may be the right choice for you. If you don’t need more torque, then the GPH01 and the GDT01 will serve you well.
The combo kit (GT202SU1D1) with drill, driver, two batteries, and charger retails for $500. The cost of each bare tool separately is $260 for the drill (GPH03) and $230 for the impact driver (GDT04). makitatools.com
