Why the Extended Shank Design Improves Your Workflow
The magic behind the SC-42 L3's extended 3-inch shank is that it lets you get to spots others can't reach comfortably. Imagine trying to carve out detail in the corner of a deep box—without a long handle, your tool feels cramped and hard to control, right? This burr's longer shank acts like a longer paintbrush handle, giving your hand more room to maneuver and steady your strokes. not only does this reduce fatigue, but it also helps you keep consistent contact with the work surface, improving finish quality and saving time by reducing tool swaps.
