Why the Double Cut Provides Smoother, More Controlled Finishes
The double cut design of this burr cleverly combines both right and left-hand flutes, giving you a balanced cutting action. Think of it like two sets of tiny chef’s knives slicing at once but in opposite directions—this cuts the material more finely, leaving a cleaner, smoother surface. Plus, the slight left-hand twist helps you keep a firm grip on the tool, boosting control and reducing kickback. It's like having a burr that works with you, not against you.
