Awesome router bit!
Wow! What a difference over my other traditional carbide two blade slot cutter! This thing is cuts so smooth even on hardwoods. I bought it for making box joints and it didn't disappoint. I highly recommend these bits.

Brought for use with my CNC machine.
Good brand. It worked fine in my Shark CNC. It's had heavy use and still cuts cleanly. I'd buy again.

Top of the line cutter. My trim routers love it.
These cut like a champ. Nice clean cuts. Do not cut with the veneer up. You won't be happy. Just saying. Up-cut bit have their purpose and do s great job. Whiteside does it best.

Would buy again
As a fairly new woodworker, I finally had the opportunity to use this with my router and straight edge. It's very sharp and fast. I had no problem with accuracy of the cut, so I feel it was a good purchase.

Fantastic router bit for the money
This 1/4 inch plunge bit held up really well to cutting through red oak in 1/4" deep passes. It stayed pretty sharp for most of the time that I was using it to make some vents. I ended up cutting about 84 feet of 1/4"x1/4" grooves and it didn't burn the oak or create tearout the entire time.
