Waste of money. Not fit for purpose.
0 stars. Bought 2 as have 50 sheets of 12mm cement board to cut and both have sheared and broke after 1 hour. Don't waste your money.

Not robust enough for the price
Worked well while it worked, however the cutting blade sheered off after about an hours use. The blade is not made from sufficiently strong material to last and the manufacturer does not sell replacement parts. Overall not worth purchasing unless you are only doing small and occasional tasks.

UK plug needed
Great tool but nowhere does it state its a two pin plug you receive so if you were expecting to use it straight away using a 3 pin 240v appliance plug you would be very disappointed. Of little use in the UK originates from the USA.

I was a bit leery at first, not sure it would work properly on a 18v plus drill. Boy was I wrong. This tool is a must have for Fiber cement siding. It is quiet, smooth, and quick. No Dust, and no flying particles. I was amazed at the tools performance. It cuts curves perfectly, as long as you can keep a straight line, and it makes cutting the boards a breeze. I cannot say enough great things about this tool. This was our first attempt at installing fiber cement siding on our new house, and the tool help take a bit of the stress away. I love it. The dual sided handle makes it great for stability.

I have used this all summer to install Hardie lap siding on my house and it has worked like a champ! Once you get used to it, you don’t need to use the handle but can steer the tool easily with the one hand holding the drill freeing up your other hand to hold the material or lift it off a saw horse to go over. It’s so nice to have minimal silica dust in the air! Does leave a rough edge and hard to cut a perfect 90 so not for butt joints unless you use a masonry blade on an angle grinder (highly recommend) to smooth the edge first. I was able to borrow a guillotine style shear from a friend for the straight 90 cuts all the way across the board which also creates very little dust.

Great little unit, works even better than the makita standalone Fc battery cutter. Clean cuts easy to angle up to do tight curves, and the offcut ejecter arm makes sure no curls of cuts impede vision of the cutter gap when working. I use this with my milwaukee m18 drill and it works a treat. The only downside is that you have to use two hands but that's hardly a big deal.highly recommend for anyone that has to cut blueboard villa or Fc sheets quickly and effectively
