I bought this bit for a project I was working on. It cut very smooth and clean but I had a little problem thinking it was a grain pattern. I called Whiteside and Tech Todd spent 30 minutes of his day explaining to me how to fix these problems. Not only did his advice work, he asked me to call him back and let him know how the project ended. Now it's about customer service. I will never buy any brand other than Whiteside. Thank you Todd!
