Freeborn No. PC-18-001. Three wing, 2” high, 1-1/4” bore, carbide steel knives that can handle anything from hardwoods to MDF. The cutter head profile allows one set up to be use for both boards to be joined: just reverse one board. The profile provide ample glue surface for super strong joints while also automatically registering the boards, eliminating slippage during gluing and helping to guarantee perfect alignment every time. With a 45-degree jig, this can work for corner assemblies identical to what production shops like Stickley use. Virtually new—very lightly used. This is one shaper profile no serious woodworker should be without. $366 new online; yours here at a 60% discount!
