Up-cut, down-cut

Feb 16, 2014 2 Replies

When the router bit manufacturers refers to a spiral-cut router bit as up-cut or down-cut, are they consistently speaking with reference to the router base? Or are they assuming a router-table orientation as opposed to a hand-held router?



The ambiguity being, of course, that a router bit that cuts away from the router is down-cut when the router is being hand-held, and up-cut if the router is mounted under a router table.

It's referenced with respect to the *wood*. Up-cut lifts the fibers up and out of the wood, down- cut cuts down into the wood.
