Review on 🪚 Yonico 37412 SC Spiral Coated Router" -"Yonico SC 37412 Spiral- Coated Router by Ken Coste

Bought this bit to replace one from another company. I thought I would save about $20. My old lure is similar to this one, coated, probably indistinguishable. My older part spent several years carving 3D models out of wood on my CNC machine. This blow lasted 10 minutes. When I brought the CNC machine back about 10 minutes after the cut, smoke was coming out of the drill. The wood (cherry) turned black from the heat of the bit. Now I have to order another bit from the company I used before. This bit's packaging said "Do not exceed the maximum recommended RPM when using this router bit", but that doesn't tell you what it is. Why don't you put this information on the packaging? Update April 19, 2018: After contacting the seller through their website to share my experience and to ask for the recommended RPM for the bit, they responded very promptly provided the RPM information sent me a new bit quickly to get the bit to replace I had. The new bit cuts quite well, I'm very happy with the customer service. I will have no problem recommending this beat to my family and friends.
