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

Best bits on the market, bar none.

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!

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.

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.

Super bit! I used it to cut a round top for an antique plant stand. Worked perfectly. Clean top and bottom cut, no fraying, no burning, and required very minimal sanding to prepare for a final routed edge. I restore antiques for a hobby/passion. This is a must have. Dont know how I got along without it.

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

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

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.

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

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.
