          It can be but you have to score it till you are about 3/8” into it. I found using a circular saw with a blade you are happy to throw away works better

            Can this be used on vinyl floor planks?

            Answer This Question

            This was designed to cut backer board and have a rather blunt edge on them, so no, Dave they would not efficiently cut vinyl floor planks. A good quality utility knife will do the job. I used the Husky Folding Lock-Back Utility Knife, which has a quick blade change feature, and it works very well for this purpose. (And no, I don't work for Home Depot, but I shop there a lot.) Just have a lot of blades handy so when they get dull, you will be able to keep cutting. I tried two ways to cut vinyl: Score and break, and just cut through. I found that with vinyl flooring, just cutting completely through does a nice job. Good luck, Dave!

            The backerboard scoring knife is not intended to be used to cut vinyl floor planks. Instead, we would recommend a utility knife or one of our Roberts Floor Cutters. Customer Care

              If the tile is already on the floor and the thinset has cured you cannot score or break the tile. Customer Care

                I've never actually tried this, but I doubt very much it would work on thick tile at all never might tile stuck to the floor. This product works well with backer board, however.

                    Great job and did the trick
                    I bought this along with cement Hardie backerboard and as a 5'4 120 lb woman, it was no problem at all cutting that cement board with this scoring knife. Not sure how many times I had to score it before I could snap the board in half (maybe 50 times???). It wasn't hard or strenuous work though. I ended up cutting the board into 4 pieces with no problem at all.

                    I used this backboard knife on 4x8" sheets of Wonder-board for 850 sq ft of floor. It lasted thru to the end of the job with no problem and is still sharp! We had to do a lot of cutting and this tool was up to the task. Forget about trying to cut cement board with a regular utility knife, this is the right tool for the job and is very reasonably priced to boot.

                    VERY easy to use. I found that after multiple boards the handle became loose. Easy fix. Just tighten the screws. After cutting about 15 times tip is still as sharp as when I bought it.

                    Game Changer
                    Compared to using a sharp utility knife that would dull on a single cut, this literally makes the job 100 times easier. The carbide tips haven't lost any bite after a hundred or so cuts so far. The longer handle allows for a lot more force than I got with the Utility Knife. About five swipes along a clamped Straight Edge and Ive been getting a pretty clean-cut.
