CMT has developed a tongue and groove cabinet making system that derives from the superior traditional European methods of joinery. The CMT Tongue and Groove Set includes a matched set that produce a 6,35mm x 6,35mm (1/4” x 1/4") tongue. The feature of the CMT system that sets it apart from other tongue and groove sets is that the tongue is offset to one side of the joint, ensuring that that it is easier to assemble flush with each other.
In some cabinet making applications, it is necessary to trim portions of the tongue. For this reason, they have included a 12,7mm (1/2") shank flush trim bit to complete the three piece set.
