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

Great bit. Compression bits are the way to go if you really need to reduce or eliminate fraying and blowouts along the cut edges. I like Whiteside products anyway, but wasnt sure how this one would handle being subjected to plywood almost exclusively. It started out plenty sharp and made super clean cuts. It did finally wear down, but gave me a reasonable amount of use life. Fit my .25in router well. Plenty of shank for the chuck, while still having a long cutting surface. Helps reduce vibration and bit flexing. As with any bit, cut at the right depth and right speed and youll prolong the lifespan even more. Im buying another one, kinda says it all.

After struggling between up and down cut spiral bits, finishing issues, and bit sharpness. I found the one. This bit is a game changer.

Makes nice clean cuts

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.

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 us this for woodworking... crushed it... no tarot, no pulling, just nude clean lines

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.

These can be pricey, but other off brand end mills can break super easy. Whitesides is top shelf in my opinion. This worked perfectly for our plywood cnc cutting. I do 3/8 step downs on 3/4 material to reduce tear out on both sides . works perfectly

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!
