This pack of 5 Finsa MDF boards are cut to a more workable size of 600mm x 600mm each. The 2mm thick MDF fibreboard has a smooth surface face and a uniform fibre structure. Due to these properties and the fact that it is a very thin MDF panel, it makes an ideal choice for use with laser machines for cutting and engraving. In addition, these boards are also suitable for CNC machining. MDF can be used for a variety of DIY and crafting applications. Medium Density Fibreboard (MDF) is a reconstituted wood panel product. Measurements (length x Width): 600mm x 600mm 60cm x 60cm 23.62 inch x 23.62 inch As a natural timber product, and as this is a very thin MDF board, there could be a slight bow or twist when placed on a flat surface. This is normal and it is recommended that the edges are taped down when used for laser machining applications. There is a small tolerance in thickness of +/-0.15mm.
