The core diameter and cross section area affects the cyclic fatigue life of files.

Oscar Uria

The core is the same, but the reciproc has M-wire technology, and the tapers are differents.

mtwo diameter 0.10 mms on D1, has a taper of 4% till D16

mtwo diameter 0.15 mms on D1, has a taper of 5% till D16

mtwo diameter 0.20 mms on D1, has a taper of 6% till D16

mtwo diameter 0.25mms on D1, has a taper of 6% till D16

Reciproc R25, has diameter 0.25 mms on D1, with a taper of 8% on it's first 3 apical mms, and diameter on D16 is 1.05 mms

Reciproc R40, has diameter 0.40 mms on D1, with a taper of 6% on it's first 3 apical mms, and diameter on D16 is 1.10 mms

Reciproc R50, has diameter 0.50 mms on D1, with a taper of 8% on it's first 3 apical mms, and diameter on D16 is 1.17 mms
