This accessory did not meet my expectations when it came to precision and finish. The industrial and scientific claims fell short, as the final product had too many imperfections.The only positive was the initial ease of use. Unfortunately, the cons far outweighed the benefits for me. I do not recommend this accessory for those seeking a high-quality finished product..

This tool exceeded my expectations and definitely made a difference in the finished product .Its precision and accuracy are top-notch, making it perfect for industrial and scientific settings. The only downside is its relatively high price but the excellent results justify the investment. Overall, a must-have in any cutting tools arsenal..
Pros
Produces smooth finishing cuts with 40-degree angles.
Cons
Requires replacing frequently due to the blunt edge.
Bought three sizes. The two smaller ones, 7/32" (68451) and 1/4" (68453), do not have a Weldon shank (flat spot). The 1/2" (68466) has it. Haven't cut it yet but otherwise looks like a good cutter.
