Exqutoo 3PCS 1/4" Shank Router Bit Set, Raised Panel Cabinet Door Making Router Bits, Cemented Carbide Router Bits, Woodworking Tools Router Door & Window Bits (Tenon Joint Cutter Diameter: 1-5/8")

Be very careful when first using these bits.They can work loose on the shank causing extreme vibration .just re check after each use.They need lots of shallow passes to produce an acceptable joint.The paint came off instantly but didnt effect the overall joint.The set produce very tight joints once set up which can be a bit fiddly just have plenty of wood the exact same thickness for it to work.No instructions came with the set but there are good instructions on the cmt website .

Very good quality

I recently purchased the Exqutoo 1PCS 1/4" Shank, 2-1/2" Diameter Raised Panel Router Bit, and I’m honestly impressed. The build quality is outstanding—solid, sharp, and clearly well-made. Setup was simple, and it performed exactly as described, producing clean, smooth cuts with no chatter. It feels durable and delivers better results than I expected, especially at this price point. I’d definitely recommend it to anyone looking for a reliable, high-quality router bit.

Well built, does the job.

They work great easy to use
