This bit can be used for cutting both a tongue and groove based on how the wood is aligned with the cutting edge. One bit makes both cuts with a tongue width of 9/32". Recommended for a material thickness of 1/2"-13/16".
straight and true. First time using Iroko. Outdoor mostly sheltered area.Not Teak but still quite pricey. KJP is a great company to deal with, like a candy store for wood
