Hyde 19408 Heavy-Duty Carbide Cutter, No Color, No Size

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!

This did an ok job of cutting the Hardibacker for my bathroom remodel. You need to score it several times and press pretty hard, but it is easy to make straight lines. I dropped it on my concrete patio and one of the two blades broke off. It must be pretty brittle, but at least there are two blades so I could finish the job.
