4-Piece 90 Degree V Groove Router Bits, 1/4 Inch Shank, Carbide Tipped, CNC Engraving Bit, Woodworking Chamfer Bevel Cutter, CNC Router Pro-Series.

They work as they should. Great bits at a great price.

so far these bits have been everything i was hoping for.

Beware. They are not really sharp and worn out fast after few times. Good if they are used occasionally.

great router bits for the price

This v-groove set was not as good as some other Align Carbide products that I've used. They bogged down, even on some very soft redwood. There was some chatter, friction, and burning, even on shallow cuts. Bottom line, they just don't seem to be very sharp. The v-profile is nice. But the bit has to work very hard so the profile of the entire cut is not as consistent as I expect. These worked much better for chamfers. So I'll keep them for that purpose. Still a reasonable value. But for v-grooves in production volume, these bits just don't "cut it" for me.

Quality product, and great help solving an issue with delivery

Was looking for a starter kit to start doing some carving/engraving. These worked perfectly.

Waste of money. I'm a professional cabinetmaker with 35 years of successful self employment. These are maybe the worst bits I've ever used. They burned on their first use; not just the wood, but the carbide as well.
