This bit was for the inside contour and worked perfectly. This was my second project using a router and first using a decorative contour. The bit bit gave the frame's inside edge a perfect finish and was exactly what was needed. Although I was a little nervous due to the size of the bit, I didn't have any issues with it. The inexpensive router I used didn't have any problems cutting cleanly through the wood with it. It cut the edge smoothly and accurately. Although I got the bit for this specific project and have only had it a short time, I can see that I may use it for other projects that may come up such as fancy table edges or door panel frames (what I think it is designed for). I initially was concerned about the price, but when compared to the cost and effort for finding and buying a replacement window frame, I consider it a good investment, even if used for only a few projects.
