Abstract

Lame de scie comprenant un corps de lame et une pluralité de dents de scie disposées sur le corps de lame, ces dents de scie étant déviées d'un angle déterminé, alternativement, par rapport à l'un des côtés de la lame de scie, du plan de ladite lame, caractérisée en ce que la face de coupe de chaque dent est réalisée de manière à former un gradin radiant, dont la face avant forme une petite face de coupe. Grâce au gradin radiant formé sur chaque dent de scie, la zone radiante de la dent de la présente lame de scie augmente, comparativement à celle de la lame de scie de la technique connue, ce qui améliore l'efficacité radiante, réduit la température des dents de scie, prolonge la durée de service de la lame de scie et maintient la résistance élevée de la lame de scie lors de sa mise en oeuvre.
