The Makita 18-Volt LXT Lithium-Ion 3.0 Ah Battery (2-Pack) charges faster and works longer than standard lithium-ion batteries, giving your cordless tools exceptional performance and productivity to take on the most demanding applications. The battery has a category-leading charge time of only 30 minutes, so it spends more time working and less time sitting on the charger, and also resists self-discharge so it's ready for use even after long periods of inactivity. It works with the Makita Rapid Optimum Charger (sold separately), a smart-charging system that communicates with the battery during the charging process to monitor current, voltage and temperature, which helps optimize battery life and deliver a faster charge. The charger also has a built-in fan to cool the battery for faster and more efficient charging, even in hot weather conditions. In addition, Makita's Star Protection Computer Controls allow the tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating.

Thank you for your question on the XMT03Z 18V LXT Lithium‑Ion Cordless Multi‑Tool. Call the Makita Call Center during business hours at (800)4-MAKITA, they’re based in Buford, GA and are ready to help.

I recently asked if the Makita 18 volt 61/2 in.cordless circular saw could be used with the batt...

Asked by Bruce May 13, 2021

Yes. The 5Ah will last longer than the 3Ah, but all of the 18v batteries will run it. I have this saw and have used it with the 3Ah, 4Ah, 5Ah, and even a knock-off 6Ah, all equally powerful.

is this tool brushless?

Asked by ccab May 7, 2021


What comes in the box?

Asked by edt70 April 7, 2021

This is the tool only model and it only comes with the items listed in the description.

What is the cutting depth at 90-degrees?

Asked by Allan February 2, 2021


How does this compare to corded version?

Asked by Lee January 13, 2021

I have a corded Multi-tool from another manufacturer that is Yellow and Black. The Makita cordless works equally as well and is among the best Multi-tools I have used.

Can I use my Makita Li-ion 18v BL1815N battery to power the saw? Thank you

Asked by Martin December 16, 2020

Thank you for your question. Yes, The XSS02Z 18v 6‑1/2" Circular Saw can be used with the following standard battery cartridges, BL1815N,Bl1830,Bl1840,Bl1830B,Bl1840B,Bl1850b,Bl1860B.

Will this saw cut metal studs?

Asked by Yeye December 4, 2020

Yes but you will need to purchase a metal cut off disc like the Diablo 6-1/2 in. x 1/8 in. x 5/8 in. Metal Cut-Off Disc sold by Home Depot. They only cost like $2.99 and will allow you to cut steel, stainless, cast iron, sheet metal, copper, ect.

Combine this multi tool with a 5Amp Battery and it will not let you down! HIGHLY recommend and will absolutely buy again if mine ever breaks. I use this daily for work, cutting subfloor, drywall, and other miscellaneous things for work and I always know I can count on my multi-tool. Easy to use. Easy to understand. Has six different power modes set in the side- super easy to learn. I love it.

XT333X1 - True Review
This was purchased during the 2018 Black Friday Deal and it came with x4 BL1850 batteries (separate packaging) I have been using this kit for over a year now and it has standed to everything I could have expected. Pros: Durability, Brushless, Power, Quite, Lightweight, different options of batteries Cons: Only a single bay charger - obviously this is a stretch for the price but being that this comes with x6 batteries but only 1 charger port makes swapping out batteries more important and having to take breaks to charge the batteries is a little annoying. XDT13Z This is the workhorse for me doing any driving and screwing things in. It has multiple speed and is the most important tool in the bag XPH12Z This does wonders with out stopping. Ive cut up to 4" holes with this thing with ease. XSH03Z - This cut wood and plywood with ease, I have not cut anything else using this saw so I cannot review it on other matierals but could not image that having another blade would make much of a difference. DC18RC Only bad part is it comes with a single bay charger. I would recommend this to anyone that is interested in a Makita kit. This is a brushless line at a brushed price.

This saw works really well. It is lightweight and easy to operate with either hand since you can easily see where the blade contacts the wood from either side. I wondered if it would have enough power but it really cuts fast and clean. Also I doesn't seem to be as loud, when cutting, as my big corded circular saw. I got it in a kit with a battery and charger. The battery that came with it and the batteries from my other Makita LXT star tools all work interchangeably without problems or modifications. Its already been knocked off the bench on to the ground (outside) a few times and has not suffered any damage not even a crack. Along with this saw, there is a 20yr old 12V Makita drill driver in the attached image that still works! That's even after being dropped on the concrete from 8ft up several times. No, it is not compatible with the LXT star tools.

Lightweight with no sacrifice of power. Long lasting battery, the kind of tool that makes me want to switch all of my battery operated tools to Makita. Excellent product at a low price point. Perfect for tight spaces!

Will I have a lot of the Makita 18 volt tools and it's just another piece to my stuff and I like it very much it works very nice I wished I would have bought it sooner Makita Batteries are the best they last per charge longer than any cool I've seen out there and I work with guys that have DeWalt they have the generic brands and rigid Milwaukee their batteries easily per charge Outlast any of those other ones are named by 30%
