Hi splitcanoe
This is one type of bit you want in your router bit tool box, they can do many router jobs ...
Here are some links and some info about what type you should have.
----------------------
Spiral Upcut and Downcut Bits

Spiral Upcut Bit
2 flute flat bottom cutters. Top quality micrograin solid carbide.
Will cut faster, smoother and stays sharper longer. Produces a very clean, fast and accurate cut with minimal chatter. Upcut spiral helps remove material. Ideal for making mortise and tenon joints.
Downcut spirals help hold the material in place while using handheld routers. Will plunge cut and plane edges.
Eliminates chipping at the top of the cut. Ideal for soft & hard woods, plywoods & composites, laminates, plastics and some non-ferrous metals.
Spiral Flush Trim Bit

Spiral Flush Trim Bit
Get state of the art results in flush trimming, pattern or template work.
The 2 flute solid carbide spiral bits have two ball bearing guides.
Great for use where chip-out is a concern with plywood, melamine or other laminate surfaces.
Downcut bit is for hand held router applications. Upcut bit is for table mounted router applications.
Overall length for 1/4" bit is 3" and for 1/2" bit is 3-3/4". As seen and recommended in WOOD® Magazine (#158).
Compression Up/Down Spiral Bit

Compression
Up/Down Spiral Bit
This 2 flute solid carbide bit is needed to get clean, chip-free and splinter-free cuts in composite sheet goods such as Melamine or 2-sided Formica/Laminates and veneered plywood.
The Up-shear/Down-shear design of the bit cuts toward the center of the sheet from both sides at once, saving time and eliminating waste.
