On the C3D site, the cutters do not indicate whether they are UP or DOWNCUT. I am looking for other, more reasonably priced (read CHEAP) bits on Amazon to try out, and want to make sure I get the right thing.
TIA!
#201 - Upcut
#251 - Downcut
The 251 specifically says downcut. I think if it doesn’t say, people just assume upcut.

thank you!!! I am wondering, have you heard of the combination UP/DOWN cut bits? I just picked one up to play with.

The #251 is down cut. The #201 is up cut and is a 3 cutter end mill. The #251 has 2 cutters as well as the #205 up cut but. I am not fond of the #201. I use Whiteside up and down cut bits as #205 and #251 in cc instead of making a custom tool. The Whiteside bits are close enough to #205 and #251.
These are known as “compression” tools.
We sell one:
#46170-K .25" 2 flute compression cutter
in:
They work well, but one has to get the cut deep enough to engage the upper part of the cutting flutes which has downcut cutting geometry.
