Pac-Flex Post Secondary Drills, Yellow, Size 0, 1/Box

Pac-Flex Post Secondary Drills are endodontic instruments designed for countersink preparation in the Pac-Flex post system. The tapered tip provides a smooth transition between post and root canal, while the split shank redirects insertion stresses toward the post rather than the root. Sharp threads cut into dentin instead of compressing it, and a venting channel avoids hydrostatic pressure during cementation. Color-coded blister packaging allows for easy identification, storage, and handling.
