Excellent Bits. I will not buy any other brand as long as they stay in America! The quality is there, amazing for sap grooves, they don't burn wood and give amazing results.
Like all of my Whiteside cutters, this cutter worked great when I made a "juice groove" on a cutting board. Do not incinerate or throw away. I think Whiteside does the best stuff.
For those new to woodworking or routers, Whiteside router bits are of the highest quality and made in the USA. This drill worked exactly as advertised and produced a quality cut with no burn marks on hard maple leaf. Whiteside is not the cheapest piece on the market. But the old adage "you get what you pay for" applies to this product. I recommend it.
