A mat cutting device has a planar base for supporting a mat to be cut, the base having a pair of supports, each at opposite sides thereof with a guide rod mounted therebetween and having a longitudinal axis parallel to the base. An elongated cutting head having a blade at one end thereof is mounted at the other end opposite the blade on the guide rod, the cutting head being longitudinally displaceable therealong and pivotable about the rod axis, the cutting head being engageable with a movable stop mounted on one of the supports and being axially adjustable for stopping the cutting head at a predetermined distance from the support and for keeping the cutting head with the blade thereof tilted upwardly for allowing insertion and removal of the mat therebeneath. The cutting head is provided with a blade holder which extends through the head, parallel to the rod axis, and engages the blade in a transverse slot formed in the holder and secures the blade in indexing grooves formed on at least one side of the cutting head, the grooves being formed at different angles for allowing the blade to make bevel cuts and straight cuts. A slide block pivotally mounted on the cutting head rides along the surface of the mat and holds it down while maintaining the depth of cut of the blade.
