I installed a maple log countertop with a farmhouse sink underneath. The bit was needed to cut the countertop flush with the sink. Worked great! Sharp as a razor! I could have made a pillow out of shavings, they were so smooth and light, no chips or bleeding. No burn marks, although the user must check this. The bit stayed sharp after many passes. Spend money. $20+ is better than a thousand for a new countertop!
