Why the 7-Degree Taper Makes a Big Difference
That 7-degree taper might sound technical, but here’s the scoop: it means the burr gently narrows toward the tip, making it easier to work in tight or angled spaces. Imagine trying to reach a tight corner with a blunt tool—it’s tough! The taper is like having a tool that naturally fits the shape of your project, allowing smoother cuts and better control. This design helps you get right into those tricky spots without accidentally gouging or slipping.
