Real-world uses and setup ideas

The rounded tip helps reduce chatter and yields consistent edge quality across the groove surfaces, while the larger diameter supports broader channels for decorative or functional purposes. It’s a solid choice for cabinetry panels, furniture details, and architectural woodwork where clean, repeatable grooves matter.
