Makita CXT 12V Line Trimmer UR100DZ – It’s a 12 Volt String Trimmer !

Makita’s 12V CXT power tool line is the fastest growing 12V line right now and it certainly shows with new tools constantly coming out like their newest outdoor power tool – the Makita CXT 12V Line Trimmer UR100DZ. This is their first 12V string trimmer!

This was spotted over in Australia thanks to Glenn. Great news for those of you in Australia while the rest of us here in the USA have to wait our turn. I do not know when or if we’ll get this here.

Being spotted in AU all the specs are in metric. What we know is the new 12V string trimmer appears to be very light weight coming in at 2.1 kg which translates to 4.62 lbs. I’m guessing this is the weight without battery but either way this tool will be extremely light. Light on weight but not so light on where it counts as it gets a respectable 260mm cutting swatch which translates to 10 inches, that’s not that far behind most of their 18V string trimmers actually so it’s pretty good in my opinion.

It uses 1.6mm line which is 0.062″ when translated which is thinner than traditional line but we’re talking about a 12V string trimmer here. Being a 12V tool I didn’t expect it to have dual line cutting and my guess is correct as it only uses one line to cut. Other features include a telescoping handle, the motor is mounted on the cutting head and a 10,000 RPM no load speed. I didn’t see the mention of variable speed so this will probably be the fixed RPM speed, in other words you’ll only get max speed at all times. Makita doesn’t talk about runtime but they say this is good for homeowners with small to medium yards.

    Makita are really starting to take it to Milwaukee in the 12v line. They just keep dropping tools into the market every few weeks.

      Fastest growing 12V line at the moment!

      • glenn says:

        I finally ordered one of these last week but it is currently only special order so I wont receive it til 12-14 of March.

        After I get it and have a play I will post a few comments on it if that is ok.

        • Javier says:

          Sounds good. Looking forward to it!

            I received mine yesterday but although I had time to assemble it, I have not yet had the opportunity to use it so just some initial impression for now.

            It is very light, and indeed weighs only 2.1kg with a 4.0ah battery. It needs some minor assembly, being that the line guard needs attaching as well as the adjustable mid support handle.

            It comes with a spare reel of line that looks to be able to fill the spool as well as a shoulder strap and a bag that fits over the line head for clean transportation in a car etc.

            It is adjustable in length from a very compact, measured somewhat inaccurately, 870mm to a full length of 1500mm so it should suit most people from the shortest to the reasonably tall. The length adjustment is via a lever ala a camera tripod rather than a twist style nut which makes for very quick and simple changes.

            Overall construction is of a standard that one would expect from a brand like Makita, read, very well made and thought out.

            Anyhow, will get to use it over the following weekend and will post my thoughts on its performance.

            looking forward to your final thoughts on it

            I finally got to use it a little a few days back.

            I must add from the outset, I don’t have a lot to compare it to other than a Ryobi 18v trimmer that I currently also have, and, many years back, a Kawasaki 2 stroke trimmer which really wasn’t very good.

            Besides that I have used other peoples mains and gas powered units on occasion but not enough to make any real solid comparisons.

            Also this is far from thorough and proper review, more just my thoughts as an average tool user. Plus I will leave the real reviews to Javier! Lol!

            I live on a small block with no lawns and have well mulched gardens. As such, I only get a smallish amount of weeds growing through.

            For these purposes it works very well. It is very light just 2.1kg with a 4.0ah battery, the grip points are well balanced, it has very little vibration and is very quiet being rated at a mere 62db by Makita when free spinning.

            Power wise it is not a lot different than the Ryobi. I think this is in part due to its smaller cutting diameter, 260mm as opposed to 305mm Ryobi, as well has running at higher speed, being 10,000 rpm. If pushed too quickly into thick clumps however, it will bog down a bit but recovers speed very quickly if pulled back.

            The head is a tap and go type which works as well as any others I have used. ie; it needs a reasonably quick firm tap on average density ground.

            I did not get to test run time because by the time I had finished, it was only down 1 bar on a 4.0ah battery plus I forgot to time even that usage. But as a guesstimate, Makita’s quoted runtime of up to 38 minutes shouldn’t be too far wrong.

            Obviously this trimmer is not meant to replace nor indeed will it replace a gas powered trimmer nor any of the better 18v units, but it is more than adequate for light use on smaller blocks such as townhouses, courtyards and dual occupancies such as the one live in.

            Another bonus for those us with smaller storage areas is its compact size being just 850mm long when collapsed making it a lot easier to store than most others on the market.

            If you are in the CXT 12v Max lineup and have a smaller block this may well suit you. It is certainly well up to my needs and I do not regret buying it and will be selling the Ryobi 18v trimmer.

            I hope the above helps if anyone else is interested in purchasing one.

          • Javier says:

            Thanks for your full thoughts. Sounds like it’s not bad for a 12 volt unit.

          • glenn says:

            No worries! I hope the info came across as impartial and helpful. Yes, I feel it’s pretty good and in fact better than I originally expected considering the voltage. But being a top brand I figured I would just take the punt and buy it.

            Now we just need Makita to release a brushless compact blower, a dremel type rotary tool, a circular saw like the M12, a spot polisher and I will be completely swapped to the CXT lineup lol.

    This 10,000 rpm Makita CXT string trimmer has finally come to the USA, as the RU03ZX. It replaces the less-powerful RU03Z, which was derated to 9,000 rpm. Home Depot is listing both old and new: The RU03Z for $90, the RU03ZX for $94. Unfortunately, most buyers–and probably most sellers–won’t figure out the difference; Makita USA hasn’t announced the new model much less explain how it’s better.

    • Javier says:

      After looking at the Makita USA site’s specs, all three models are identical and basically the same exact unit with the same exact specs including all with 10,000 RPM. The only difference between the two USA models are the head it comes with. The Z uses a regular line bump feed string trimmer head while the ZX uses a single cutter plastic blade head. Otherwise all the same unit.
      Thanks for spotting the USA variants!
