FIELD: process engineering.SUBSTANCE: invention relates to woodworking, particularly, to saw discs. Saw blade comprises main flat body of circular periphery. Multiple seat for tips are arranged on said main body and shifted in circumference. Said tips are soldered to said seats. Every cutting tip has locating base composed of two locking surfaces. Locating base is soldered along said locking surfaces to appropriate seat of the tip. In compliance with second version, multiple tip bearings areas are arranged on saw body to alternate in circle and multiple recesses between teeth arranged in gaps between said tip bearing areas. One of said locking surface comprises curved concavity conjugated with curved convexity of another locking surface of appropriate tip bearing area. Another one of said locking surface comprises curved convexity conjugated with curved concavity of another locking surface of appropriate tip bearing area.EFFECT: efficient resistance to forces acting on saw blade from different directions.12 cl, 6 dwg |
