This may be a day late and a dollar short, but I didn't have any time to research this one before I made the purchase. The "purchase" being a grab-bag of 1/2" shank router bits, plus two rosette cutters for a real good price (I though so, anyway!) At any rate, the bulk of them are Carb-tech bits. Now I realize they won't rank as high as the Whitesides, Amana's, Freud's, CMT's and the such. Still, I'd like to hear from past/present users. The main reason being, a couple look like they could use a little dressing up in the sharpening dept. and I'm wondering if it would be worth the expense. Appreciate any info...
