Makita model numbers end in letters: Z means tool only. In kits the letters name the battery (T = 5.0Ah, D = two 40V 2.5Ah). Some kits (XFD131) use a different number from their tool (XFD13Z): the box list on each page names the tool.

What the Makita ending does not tell you

Rules checked 2026-10-18 against the box lists on Makita's own pages; the box list on each page is authoritative.
Makita does not publish a tool-only weight for most cordless tools: its weight figure includes a battery.

"Usually" means we found exceptions or too few examples to call it a rule. The box list on each model page, taken from Makita's own page, is what to trust. For battery counts and sizes across every kit we cover, see what ships in each kit.
