Review on GREENWISH Hardness Woodworking Tungsten Spherical by Michael Laird

According to my experience, this router bit was a complete waste of money .It was advertised as being great for woodworking, but it didn`t live up to the hype. The quality of the product was terrible and it broke after just a couple of uses. The bit is supposed to be ideal for hardwoods but I found that it struggled even with softer woods. Overall, I would not recommend this product to anyone looking for high-quality industrial and scientific cutting tools..
