Makita GT401M1D1 40V max XGT Brushless 4-Pc. Combo Kit (2.5Ah/4.0Ah) with GPH01Z Hammer Drill review

GT401M1D1 is a current-reference Makita 40V max XGT four-tool combo kit, not a drill-only bundle. Its exact U.S. product page names the GPH01Z hammer driver-drill, a separate GDT01Z impact driver, GRJ01Z reciprocating saw and ML001G flashlight. The same page lists one BL4025 2.5Ah battery, one BL4040 4.0Ah battery, a DC40RA charger and a tool bag. This assessment separates that exact M1D1 package from nearby kits and from the GPH01Z tool-only configuration; it does not claim use, testing or present stock.

Which tool drills, and which ones do not

The included GPH01Z is the only drill in this four-piece set. Its manual documents rotation drilling, screwdriving and hammer drilling, while the product page identifies a brushless 1/2-in hammer driver-drill. GDT01Z is a separate impact driver; GRJ01Z is a reciprocating saw; ML001G is a light. Their inclusion does not add another drill or alter GPH01's operating modes. For a buyer who wants the drill plus these complementary tools, this is a distinct package case. If the other tools would remain unused, the set's larger component count is not by itself a fit reason.

Makita lists up to 1,250 in-lb of torque, 650/2,600 rpm and up to 39,000 bpm for the GPH01. The manual specifies different capacities for different bit/material combinations: 13/16 in in steel and masonry, 2 in with a wood auger, 3 in with a self-feed bit and 6 in with a hole saw. These are manufacturer limits, not test results or assurances for every material, depth or application. Hammer-driver-drill describes a chuck-based machine; it is not an SDS rotary hammer or a chipping tool. Use the specified bit and follow the manual's control, auxiliary-handle and torque-reaction instructions for the work.

Two battery sizes, not a matched pair

The kit page explicitly lists one BL4025 2.5Ah pack and one BL4040 4.0Ah pack, plus DC40RA and a bag. The GPH01 manual names BL4025 and BL4040 and DC40RA among applicable power equipment. The two pack models are different capacities; do not describe them as identical spares or infer runtime from the amp-hour label. Check the exact battery and charger model if integrating existing XGT equipment, and consult the current regional manual rather than relying on voltage alone.

GT401M1D1's exact page reports a package size of 15.59 by 8.62 by 26.42 inches and a shipping weight of 31.11 pounds. These numbers describe the shipment, not the GPH01 bare tool, the loaded bag or an operating setup. The drill manual gives 6.0–6.6 lb depending on battery and attachments, but that range is neither a bare-tool value nor the weight of the four-tool package. The page's written list does not separately name a side handle; confirm exact kit contents if it matters, rather than relying on a staged image.

How this kit differs from its neighboring packages

GT401M1D1 sits between two separately reviewed GPH01 packages. The two-tool GT200D lists GPH01Z and GDT01Z, two BL4025 batteries, DC40RA and a bag. The five-tool GT500M adds a GSR01Z rear-handle circular saw to the GPH01/GDT01/GRJ01/ML001G group, and lists two BL4040 packs with a wheeled bag. Those are separate retail configurations, not upgrades implied by the shared drill model. Compare the written package list and exact suffix, not just the GPH01 name or a photo.

The manual gives the GPH01 a 7-1/8-in overall length, not a head-only measurement. No reviewed source establishes a tool-head length of 6 inches or less. A short-recess job also depends on chuck and bit protrusion, hand position, the side handle and the installed battery. Measure or confirm the actual needed clearance rather than using shipping dimensions or the overall-length label as a proxy.

Who should consider the four-tool format?

This is a reasonable package to compare when the named drill, impact driver, reciprocating saw and light all serve planned tasks, and when the two different included XGT batteries and DC40RA fit the user's setup. It is less compelling to a buyer seeking a single compact drill or a kit whose included packs match one another. The available record supplies no independent performance comparison, tested runtime, price, availability, seller condition or customer experience. The decision should turn on the precise tools and packs in the box, the GPH01 manual's limits, and whether the extra equipment belongs in the work plan.
