Review on Precision Cutting with CMT 191 507 11 Carbide Spiral Diameter: Optimal Performance Guaranteed! by Jeff Jackson

3 stars for now as I'm not sure if it's authentic. I mostly have CMT and they all have CMT engraved on the bit this one doesn't. I posted a question about this. Here's what I put together: 1/2"x2"x4" - size, Z2 - two cutting edges, POS POSITIVE SPIRAL, HWMHigh Water Marks, MAN Manual Feed, RH Right Hand I don't know or cant find out what 18 means -5982 nmax24000 e01 not sure i will update once i know if its a real CMT, if i rate the CMT bit it would be 5 stars However, the bit purchased from Prime Time Solutions is not genuine because it has no CMT etch I have requested and accepted a refund but I have still not received a response from them regarding my missing CMT etch, I had a choice To order from my point of view Routerbitworld is a great place to shop because the price and customer service is excellent but I chose World Class Supply as they answered my question and they are a really good organization too. The second picture is what I got expected CMT engraving on a bit purchased from World Class Supply
