Why the Double Cut Design Makes a Difference
Understanding the double cut on the SJ-42 means appreciating how combining right and left hand flutes lets this burr glide through metal more smoothly than a single-cut. Imagine holding a pencil and rotating it both clockwise and counterclockwise smoothly — that’s the balanced action it brings. This results in less vibration, excellent control, and a finish that’s super clean without sacrificing speed.
