Makita GT400M1D1 40V max XGT Brushless 4-Pc. Combo Kit (2.5Ah/4.0Ah) with GPH01Z Hammer Drill review

GT400M1D1 is Makita's four-tool XGT combo configuration that includes a GPH01Z hammer driver-drill. Its role is not just “a drill with batteries”: the other included equipment changes the package's appeal, and the exact item list distinguishes it from another four-piece XGT set with a different saw.

The drill component and its limits

The manufacturer names GPH01Z in the GT400M1D1 package. The separate GPH01 manual documents a 1/2-inch keyless chuck, rotation drilling, screwdriving and hammer drilling. It is a conventional chuck-based hammer driver-drill; the separate GDT01Z impact driver in this combo is a fastening tool, not another drill mode or a substitute for hammer drilling. This is not an SDS rotary hammer and the manual does not describe a chipping function.

Makita's GPH01-family specifications include a two-speed 650/2,600-rpm range, up to 39,000 blows per minute, and a 1,250-in-lb maximum-torque figure. Treat those as maker-stated specifications rather than results from independent testing. The manual provides material-specific capacities and safe-use instructions; a stated 13/16-inch masonry maximum does not mean every masonry type, bit and hole is suitable. The half-inch chuck value means shank fit, not hole diameter.

What the GT400M1D1 list says is included

The exact package page lists GPH01Z hammer driver-drill, GDT01Z impact driver, GSH01Z 7-1/4-inch circular saw and ML001G flashlight. The package also includes one BL4025 2.5Ah battery, one BL4040 4.0Ah battery, a DC40RA rapid charger and a tool bag. The page does not give that bag a separate model number or describe it as wheeled, so those details should not be inferred from another Makita kit or image.

This exact mix is useful to compare with GT401M1D1. The two four-tool SKUs share the GPH01Z drill, GDT01Z impact driver and ML001G flashlight, and both list a BL4025, a BL4040, DC40RA and a bag. GT400M1D1's fourth tool is the GSH01Z circular saw; GT401M1D1 instead lists the GRJ01Z reciprocating saw. If the type of saw matters, the SKU suffix—not the common “4-Pc. Combo Kit” label—is the deciding evidence.

A kit for a multi-tool XGT setup

The package makes most sense to someone who expects to use a hammer drill, impact driver, circular saw and flashlight and wants the two different-capacity packs listed in one purchase. A BL4025 and a BL4040 are not a matched pair, and the larger capacity does not by itself establish a particular runtime or charging schedule. Use the exact battery and charger instructions for the drill and other tools rather than extrapolating from nominal capacity.

For a buyer who already owns XGT batteries and a charger, this package may duplicate equipment; for someone wanting only a drill, it adds three other tool bodies and storage needs. No price, stock, seller condition or bundle-value comparison was verified here. The fact that batteries and a charger are listed establishes package contents, not a claim about what the kit costs relative to buying tools separately.

Fit and package checks

The GPH01 manual's stated 7-1/8-inch dimension is overall length, not tool-head length. Its published weight range depends on battery and attachments; it does not establish bare-tool weight. The exact GT400M1D1 page also does not separately list a side handle, so verify that item if your planned operation requires one. Check the drill's head, battery, hand and bit clearance in the actual space rather than using package dimensions or overall length as a proxy.

Before choosing the kit, verify the exact GT400M1D1 marking and its GSH01Z saw, then decide whether its mixed BL4025/BL4040 battery pair and other tools fit your existing XGT setup. Compare it with GT401M1D1 only after deciding whether the circular saw or reciprocating saw belongs in your work. The evidence supports those package differences and the GPH01 drill modes; it does not support a hands-on comfort verdict, measured performance ranking, or universal masonry suitability claim.
