Wide Compatibility
- Tungsten carbide router bits fit for CNC Router Machining Center, Woodworking Machine, etc.
Individual Storage Case
- Each bit is well packaged in a plastic storage case. Easy to store and use when you need it.

Compare the UP cut with the DOWN cut
- The down cut bit (left) leaves very clean edges while the up cut version (right) is far better at evacuating chips but that action can fray the edges of the cut to some degree.
- Up cut bits are very efficient at evacuating chips from the hole or slot it is cutting. This is especially important when the hole is ¼"-deep or more. Deep holes or grooves still have to be cut using multiple light cuts, but the upward direction of the flutes while rotating prevent the debris from building up in the hole and binding or even breaking the bit.
- Down cut bits require a slightly slower feed rate. This reduced pace allows the bit a little more time to throw chips out and for them to be re cut into smaller pieces that eventually are thrown from the hole or slot
