The Makita XRH05PT uses two 18V LXT batteries in series to deliver 36V power through an SDS-Plus chuck, providing 2.9 ft-lbs of impact energy for heavy-duty concrete drilling up to 1-9/16 in. and light-duty demolition. The kit includes two 5.0Ah batteries and a Rapid Optimum Charger for all-day cordless performance rivaling corded rotary hammers. Three operating modes, brushless motor technology, and dual battery runtime make it the most powerful SDS-Plus hammer in the LXT lineup.
How does the XRH05PT achieve 36V using 18V batteries?
The XRH05PT uses two standard 18V LXT batteries connected in series internally, creating a 36V circuit. Both batteries are inserted into separate slots on the tool. This approach lets you leverage your existing 18V battery investment while unlocking 36V performance.
Is the XRH05PT an SDS-Plus or SDS-Max tool?
It is an SDS-Plus tool despite its 36V power level, with a max capacity of 1-9/16 in. in concrete. This makes it the highest-powered SDS-Plus rotary hammer in Makita's LXT cordless lineup and covers anchor sizes not achievable with standard 18V SDS-Plus tools.
How does the XRH05PT compare to the XRH07PTU SDS-Max tool?
The XRH07PTU uses an SDS-Max chuck and delivers more impact energy (3.8 ft-lbs), suitable for 2 in. and larger diameters. The XRH05PT tops out at 1-9/16 in. with SDS-Plus accessories, which are more widely available and less expensive. Choose XRH05PT for medium-heavy work; XRH07PTU for heavy demolition and large core drilling.
Can I use only one battery with the XRH05PT?
No. The XRH05PT requires two 18V batteries to operate. Both battery slots must be filled to complete the 36V series circuit. The tool will not function with a single battery.
What is the runtime advantage of 5.0Ah batteries in this kit?
With two 5.0Ah batteries in series, you effectively have 10.0Ah of capacity at 18V (or 5.0Ah at 36V). This provides substantially longer drilling sessions between charges compared to smaller 2.0Ah or 3.0Ah packs.
