SPO31 mortise end .200" up x 1/2" shank x 1/2" cut dia. x 7/8" cut length x 2-7/8" O.A.L. Compression 2+2 spiral bit.
Great for chip free cut on double sided laminates. Mdf, melamine, etc. The up spiral on this bit is about .200" long, making it just right for dado's and rabbeting with the same bit you use to nest out parts with. This bit is also good for cutting out thinner material like 3/8" thick melamine because it still allows you to get a compression in the middle of the cut making it a clean cut on both sides.
