Whiteside Router Bits UD2102 Up/Down Cut Spiral Bit with Solid Carbide Compression and 1/4-Inch Cutting Diameter

I have used compression and downcut bits from all of the big manufacturers as well as the no-name, budget bits. Some that are nearly double the price of this bit. But this one has given the cleanest cut on the face and back of the material I use. I have run two 3/4”, one 1/2”, and one 1/4” maple veneered 4’x8’ MDF sheets full of parts cut all the way through with the same bit and it’s still holding up just fine. You can barely notice any wear. I think I have found my new workhorse.

I spend a lot of time using router bits. Normally I go with the most cost effective (cheap) I can get at the local box store. These Whiteside bits are no joke and well worth the extra $. I’ve used it multiple time and it has yet to snap or dull.

For my money, Whiteside router bits are the highest quality, best/cleanest cutting router bits available. They stay sharper longer than any other brand that I have tried. Bonus points for being American made in North Carolina.

Bought this to cut out holes in maple-faced 1/2 plywood. Cuts very clean on both sides. No clean up required. Works, not much else to say!

I have been extremely impressed with this bit. Purchased it to cut 1/4” grooves for drawer and box bottoms but have found several other uses for it. Love it so much I ordered the 1/2” astra coated version from bits and bits.

Works great. Nice and clean up and down cuts. Happy with his purchase.

What I like about this Whiteside compression cutter is that the upcut portion at the end is nicely compact which makes the tool usable in thinner material than many other options on the market. These are my go to small compression cutter for CNC work.

Lasted longer than bits twice the price- so far it has cut double the material we cut with more expensive bits and still going- worth it

Used on my CNC. It cuts plywood well. If I use it to drill a quarter inch hole (straight up & down on the Z axis) it seems to cut a slightly oversize hole. Other 1/4 endmills are more typical of what I get using a standard drill bit in a drill press -- a tight fit for a 1/4 dowel.

I use this bit for cutting numerous MDF parts on my benchtop CNC. I leave a clean edge on the top and a decent edge on the bottom. Definitely worth the money and I will be buying more as needed.
