I use downcut bits almost exclusively for cutting hardwoods.
I'm mainly cutting wood on my machine and was wondering if anyone uses downcut bits on their machine....I hate sanding parts with a passion and wondering if down cut is a good way to go? or would they get too hot on wood??

and how is the result with those? i'm assuming little to no sanding required..?
Where is a good source to get some...i ordered all of my tools from shars.com, but they have nothing for down cut...

Nice questions. I really need also a good supplier.

Depends on what your doing, and what type of wood. Also depends on how well the parts are held down, and how rigid your machine is.and how is the result with those? i'm assuming little to no sanding required..?
I sand everything that I do, but what I do requires it.
Most of my tools comes from Vortex Tool: Solid Carbide Router Bits and Compression Spirals for woodworking, plastics and non-ferrous industries. or Onsrud.

Downcut spiral for pocketing, rebates etc compression spiral for contouring. Upcut spiral ball nose would be the only upcut bit I would use personally, upcut endmill spirals have little or no use for wood imo.
They are good for cutting vertically mounted boards, mortise and tenons, and box joints.upcut endmill spirals have little or no use for wood imo.

Downcut bits are very common woodworking tools. You won't find them at places like Shars, that sell tooling for metalworking.still haven't found a good source for downcut bits...they seem to be the minority...

Depends on the use of the mortise, and the depth. For a shallow mortise where the edge is visible, I'd use a downcut. For anything deep or if the edges won't be seen, I'd use an upcut..yeah I suppose if the mortise was very deep and small in size. You will still get furring I'd imagine so if it's not massively deep would a dc spiral no be better.
These were cut with an upcut bit.

if you cut malamene up cut, down cut compression spiral bits work well and don't chip the edges. as ger21 says it all depends on what you cut, trial and error. tools2day sale all sorts of bits they have the good stuff and free shipping, there recommended settings are close and what type of material the cutters works well with is correct.
but if in dealt ask ger21

Yonico down cut endmills are available on Amazon.ca.
I've only begun testing this brand but so far so good.
Btw it looks like the posties are going on strike soon .
Anyone who says "It only goes together one way" has no imagination.
The box joint pics I posted earlier were done with a Yonico bit from Amazon.
