    Compact and powerful. I use Dewalt tools and this tool is very useful. From cutting tile, tin, wood and chicken wire. Makes jobs so much easier. Does not take up much room in the tool box and with the variety of wheels you can get it cuts through most anything. Took me a while to finally buy it but I am very happy I did. Lots of YouTube videos showing you different ways to use this versatile tool.

    5.0 out of 5 stars Fantastic Tool
    Reviewed in Canada on May 25, 2025

    I purchased this tool to cut out the receptacles and various notches for a backsplash project. I ended up doing all the cuts with this tool. I didn't bother buying the sliding table tiling saw I was planning. I used the included tile saw, and it finished the job. It probably has lots of life left. You need a steady hand, but it is a fantastic tool. I tried cutting up cardboard with the multi-blade, which is easier than using a knife. I am sure there will be lots of jobs I have not thought of to put it to work.

    Wow, this small cutoff tool is incredibly impressive! I used it to cut my entire patio, and the results went beyond my expectations. The powerful performance it provides makes it ideal for cutting stone and masonry easily. Its lightweight design and simple handling have quickly made it my favorite tool for working with stone. If you're searching for a dependable, efficient tool that gets the job done effortlessly, this is the one you need! The cordless feature is also a bonus. The tools cut accurately, and the speed is fantastic. The battery lasted through cutting 10 stones before needing a second, but they charge so fast—just keep a couple handy.

    5.0 out of 5 stars Powerful, compact safe one handed mini angle grinder cut off tool….Brilliant
    Reviewed in the United Kingdom on February 6, 2025
    Verified Purchase
    Far more grunt than most others. It chews through steel and paver slabs with barely an audible change in note.
    It also has best cutting depth..upto 22mm or 7/8”.
    Safety First: Now it is technically an angle grinder, but don’t risk side loading cut off discs to ‘grind’ with it huh! The all metal diamond edged blades (and this tool comes with one) can be gently used side on to smooth down a cut surface because they won’t shatter on you!
    What you get is three different blades…a black fibre type 1mm thin cut off disc for metals (see above), a yellow diamond blade for multi materials and a smooth rim diamond disc for tiling work. Note when blade changing the arbor is a Left Hand thread (tightens counter clockwise).
    In operation…though you should wear ear protection, it doesn’t seem unbearably loud. Best of all it is designed for one handed use and makes cutting almost any material feel practically as easy as using scissors.
    It features a rotation reverse switch so you can make it shoot the spark stream forward instead of along your arm - Nice!
    The arbor is a less common 3/8” or 9.5mm….but a spacing ring is included for 10mm arbour discs.
    I recommend in particular the Ezarc 76mm x 9.5mm arbor diamond disc as it fits perfectly.
    .
    A word to the wise…this WILL cut 1/2 rebar and similar if you don’t have a regular angle grinder…but that is not its forté and like all its peers it is best used on thinner stock, sheet and tube. With the yellow blade it will cut thin plywood, but it is not a circular saw and chewing into 15mm ply will bog it down and burn the wood…probably not healthy for the tool either.
    Slabs…yep…in seconds it cut a half inch deep groove into a paving slab..flipped it and cut the back then a hard tap and it was in two …. Barely a minute, so easy!
    Price…phew..it is steep at £180 without battery….but, if you break the piggy bank you won’t regret it. This is a strong, high quality, performance tool which delivers.
