Review on Yonico 34240 SC Router Carbide 2 Inch: Top-Notch Cutting Performance for Professional Woodworking Projects by Chris Shepherd

Bought for my X-Carve with Aspire 8.5. These bits are excellent for 2.5D threads (stamped threads) and offer a superior finish. Unlike many of the bits I've found on Revain, these are not metric bits with imperial units. For that alone, I think it's worth the extra cost.
