Use 1/2" height for 5/8" stock. Use 5/8" height for 3/4" stock. Cuts all composition materials, plywoods, hardwoods, and softwoods. Use on table-mounted portable routers.

I was looking for a panel lifter to make panels for a bed frame I was making. Unfortunately, my router table top is slightly larger than the more common 3 1/2" pads (not enough to feel secure), so I started looking for something smaller when I came across a couple of attachments made by Freud I bought this and a Freud mortising and mortising bit at the same time and I am very pleased.I was amazed at how easily the bits cut through red oak with no (and I mean absolutely zero) nicked or frayed…
Pros
Use 1/2" height for 5/8" shank. Use a 5/8" height for a 3/4" shank.
