KOWOOD Tongue and Groove Set of 2 Pieces 1/4 Inch Shank Router Bit 3 Teeth Adjustable T Shape Wood Milling Cutter

Not much to say these are great bits and have made doing tongue and groove on the router really easy they are still sharp and functioning great would definitely buy again I've gotten my money's worth already.

I bought 13 pressure treated 1"x6"x8ft boards and turned into a tongue and groove exterior ceiling for an area on a porch to mount a TV at my most recent job. The single female slot obviously cut easier than the double, still both cut very well. Going to want to use a strong full size router. My bosch colt router wasn't enough to cut it. However my large full size metabo and these bits ripped through no problem and helped me built a great job. Really impressed for the price. Extremely impressed I should say. The fit nice and tight. Perfect and exactly what I wanted. Over 100 ft on each and still super sharp.

Overall a good deal. I've made 6 cabinet doors so far, and pretty much every major problem was user error or skill level.

High quality bits!

These worked perfectly

Placed in router tightened it as always and starter router and out come flying bit. In the aftermath the shaft is bent (unusable now) when I looked at the bit it appears that the nut was not tight on bit itself making it unbalanced in someway (this is the double blade bit). The single blade worked just fine.

First time using the bits and was pleased with performance, once I figured out to clamp a piece of wood to the sides/ends of my workpiece to prevent tearout. Seem to be good value.

Blades are very sharp.
