Review on 🔪 Freud Downshear Helix Flush 42 204: Achieve Superior Precision and Finish by Ryan Barton

Work slowly and do not attempt to remove more material than about half the depth of cut. I recommend using a speed between 3 and 4 if you are using a variable speed router as this bit is a beast and will chew through quickly. Keep the bearing lubricated and honed with a diamond hone after each use and it will cut like new for a long time. 5 minutes service. will make a world of difference as long as this bit works well for you.
