This bit works very well. I ran 30 linear feet of cottonwood over half its cutting length. I used a moderate to slow feed rate and got a fairly smooth finish. There was no sign of burns or torn grain. I am very happy with my purchase and would have no hesitation in purchasing another Whiteside drill.
Pros
Precision ground for the right balance at high speeds
Well, looks like you really do get what you pay for. I cut the sap grooves with a cheap core box cutter that came with the starter kit. All of my grooves were burned and were very painful to grind. I decided to try the Whiteside Beats based on YouTuber recommendations. I just cut my first groove with a new cutter, not a single burn mark. I will never buy cheap beats again!
Pros
Whiteside cutters are made of high quality carbide
