Crain 18" Vinyl Special Tile Cutter is a heavy-duty machine that will cut up to 18 inch vinyl tiles straight, or 12 inch tiles diagonally. It has a steel reinforced blade carrier and large, rigid base to ensure straight, accurate cutting. It comes with a straight cutting guide, diagonal cutting guide, and a self-measuring floor guide for repeat cuts at the wall. Position the floor guide against the edge of the last field tile, then slide the tile to be cut underneath the blade and all the way against the wall. When the tile is cut, the width that is cut off automatically equals the amount needed to cover the remaining sub-floor. Crain 18" Vinyl Special Tile Cutter also has built-in low-profile blade height adjustment knobs that provide fast and easy adjustment.
