I bought a cheaper set with only two cutting edges. However, had severe burn-in that required extensive sanding. I then bought this bit and had great success with no sanding required except for a final pre-process which could have been done as a touch up. I will be careful going forward and pay serious attention to these four advanced cutters in the future.
I have used Freud bits before and have been happy with them. I figured that "Square Cut" was a marketing gimmick and had little improvement over the other beats. Cut BEAUTIFUL. I love this tip and want ALL my tips to be sharpened with Quadra. When a carefree finish is important, paying a small premium for these attachments will save you time later. I will buy them every time. I need a new beat. I look forward to more and more square cut profiles but will do what I can until they do.
