Abstract

La présente invention a trait à une lame de scie alternative destinée à être utilisée avec une scie alternative, laquelle lame de scie alternative comprend un corps qui définit un axe longitudinal, une partie de fixation conçue de manière à être couplée à la scie alternative et une partie de coupe formée sur le corps. La partie de coupe comprend une pluralité de dents de coupe. Chaque dent de coupe comprend une pointe, une face dinclinaison sétendant à partir de la pointe généralement vers laxe longitudinal et définissant un creux, et une surface en relief sétendant à partir de la pointe. La lame comprend également un point de plongée formé sur le corps qui permet dinitier une coupe en plongée. Le point de plongée comprend une dent de tête et une seconde dent. La dent de tête comprend une pointe et une face dinclinaison qui sétend de la pointe généralement vers laxe longitudinal et définissant un creux de tête. La seconde dent est placée dans le creux de tête adjacent à la dent de tête et est généralement plus petite que la dent de tête et que chacune des dents de coupe.
