Hyde Tools 19408 Heavy-Duty Carbide Cutter with 3 Blades

Perfect tool to avoid having a huge dust mess when cutting cement board. Be prepared to make several passes to get a clean cut.

I purchased vinyl laminate planks to re-floor a bathroom. I don't have a work table that can secure planks, so my attempts to cut the planks with a jigsaw on a makeshift work table resulted in uneven cuts. Some how to videos recommended scoring with a utility knife to make the cuts. That was a joke. The vinyl part of the laminate was so tough, the utility blade barely scratched through it. As giving up on the project wasn't an option, I stumbled upon this cutter while looking for solutions and I'm so happy that I did.I secured my vinyl planks between scrap pieces of plank and a 12" carpenters square (heavy metal triangle thingie I also purchased on Amazon) using my hand (protected by a medium sized pot - hey, safety first) to hold the square down. I also put a thin rubber coaster between the triangle and the pot to prevent slippage. I then used the cutter to score the tile. It took me 10 to 15 scores per tile, but the cutter steadily ate through the laminate, no problem. I then scored the other side and voila! Clean breaks.Okay, so obviously this was time-consuming and if you have a large area to work with, this won't be a good option. But for the smallish area of bathroom floor that I was re-doing, this did the trick when nothing else worked. Nice clean cuts and steady progress.Highly recommend. (Oh, the price is on the high side - funnily enough, this little thingie [at $28.93] cost more than the Black and Decker jigsaw [$26.82] I purchased for this project. But, given that it made it possible for me to get my project done, it was well worth it! And I am guessing that tungsten carbide is a pricey substance, which accounts for the cost.)

you never cut cerement board by this

I had tried to score the Hardiebacker board with a box-cutter type of blade. This failed. I bought the carbide cutter and it worked well. I still needed to score the board many times, but it worked!

Wish we had found this sooner. Was cutting cement board for our bathroom with a box knife and it took over 20 scores to make one cut (and even then the board didn't snap clean). The carbide cutter took 2 passes and the board was ready to be snapped. Wonderful product!
