Pac-Flex Post Secondary Drills, Red, Size 1, 1/Bx

Pac-Flex Post Secondary Drills are endodontic instruments designed for countersink preparation in the Pac-Flex post system, comparable to Flexi-Post. The drills feature a tapered tip for a smooth transition between post and root canal, sharp threads that cut into dentin rather than compressing it, and a venting channel that avoids hydrostatic pressure during cementation. Each drill is packaged in a color-coded blister pack for easy identification, storage, and handling; red indicates Size 1.
