Description
The NIC Hand K-Flex (Twist Flex) File is a stainless steel hand-use endodontic instrument with a rhombic/triangular cross-section that combines K-File cutting efficiency with greater flexibility for curved canals. The twisted stainless steel design produces sharper cutting edges and more flexibility than standard K-Files — ideal for moderately curved canals. Use as an upgrade from standard K-Files when more flexibility is needed.
Key Features
- Material: Stainless steel
- ISO color-coded for fast chairside identification
- Pre-sterilized blister pack available — single-use option for infection control
- Compression-fit shank with electropolished cutting flutes
- Three working lengths — 21 mm, 25 mm, 31 mm
- Autoclavable at 121 °C / 15 min or 134 °C / 3–5 min
- 6 files per pack
ISO Color Codes
- 06 Pink · 08 Grey · 10 Purple · 15 White · 20 Yellow · 25 Red · 30 Blue · 35 Green · 40 Black · 45 White · 50 Yellow · 55 Red · 60 Blue
How To Use
- Scout the canal with #10 K-File to establish patency to working length
- Pre-curve the file by hand to follow canal anatomy in curved canals
- Use a balanced-force or watch-winding technique with quarter-turn motion
- Step ISO sizes (#10 → #15 → #20 → #25 …) progressively to working width
- Irrigate copiously with NaOCl between each file size
