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

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

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

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.

Best bits on the market, bar none.

Havent used it yet but Ive heard good things about Whiteside will update after ues.

Makes nice clean cuts

After seeing several positive endorsements of Whiteside bits on YouTube, I decided to order one to try. When it arrived it appeared to be a quality bit. About a month after receiving, I finally got the opportunity to use the bit making some 1/4 deep dadoes in plywood for 3 drawer bottoms. The bit functioned very well. Two days later, I needed to use the bit again to make 1/4 deep dadoes in some softwood (SYP) for a small pegboard frame. I routed the first side with no problem. After routing about 8 of the second side, the bit snapped in half, with the broken half falling into the router motor. I had to remove the router from the table and disassemble it to get the broken piece out, noting some scoring on the cooling fins caused by the broken bit. With this being my first experience with Whiteside, Ill have to think long and hard before I consider purchasing another. Ironically, the 30-day return window expired 2 days before the bit broke.

Boom! I use this Up/Down in my CNC all day long. It doesnt quit. This bit has become my main production tooling on 1/2 and 3/4 plywood. I have even crashed it several times- putting nasty strain on the bit, and it still holds true, and plows through Baltic Birch with no issues, tearout or ragged edges. Its a really nice cutter for the price. update: many hours of cut time on this, and it just wont quit. It just keeps plowing through plywood and plastic just fine.

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.

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