The most popular wood-based panels in furniture construction are the so-called MDF boards. MDF stands for medium-density fibers, meaning they are very fine-pored and homogeneous furniture panels, whose edges, unlike chipboard or coarse chipboard, can be screwed and nailed. However, MDF boards tend to warp or split at the edges when screws are driven in without pre-drilling. To prevent this, we developed SPAX-M: The combination of the CUT tip, which essentially drills the screw hole itself, the razor-sharp wave profile, and the small 75° milling head for flush sinking of the screw ensures that you can easily screw your MDF components together. However, we recommend maintaining a minimum edge distance of 25 mm from the panel edge even when using SPAX-M. This means for you: secure edge fastening, no splitting of the panel edges.
