If an upcut gives you a great bottom finish and a down cut a great top finish, why not have both with a compression cutter! A compression cutter starts with an up cut component usually the length of the diameter (e.g. ⅛” has a ⅛” up cut component and the rest to down cut) so get the full benefit of the cutter, your first plunge must go below that length (e.g. ⅛” or more). Compression cutters like to run a bit faster than other wood cutting bit to get the best finish along the side of your material.
Suitable for
- Composite Materials (not ACP/ACM)
- Laminate
- Melamine
- Melamine Particle Board
- MDF/HDF
- Veneered Plywood
- Softwood
Not advisable
- Hardwoods
Adam’s Tips
Albeit compression bits are primarily used for slot cutting, you can still profile cut as long as you go past the up cut component. This will give you both a perfect bottom and top finish.
Do not use these bits to drill holes or start a profile cut with a straight plunge. Use a ramp in to ensure the longevity of the end mill.

Up down 2 flute spiral cutters
I use a high quality Birch plywood from Finland. It’s imperative that I achieve a crisp finish on both surfaces and also the core of the material enabling minimal sanding! These cutters are fantastic! Well worth the money.
