The Coltene Whaledent HyFlex CM NiTi Rotary Files are a reliable choice when you're dealing with medium to large root canals that require both flexibility and strength. These size #40 files with a .06 taper and 21 mm length are made from Controlled Memory (CM) NiTi alloy, which means they?re highly adaptable and resist reverting to their original shape, perfect for navigating curved canals without transportation.

You?ll notice how smoothly they follow the canal path, minimizing the risk of ledging or perforation. The files are durable and can even be reshaped with autoclaving when they become distorted, giving you extended use. With 6 files in each pack, you?re covered for multiple cases while maintaining consistency in performance.
