Abstract:
A band saw blade with teeth having a tooth point with a tooth edge (E1, E2), a tooth face on a front side of the tooth as viewed in a direction of sawing, a tooth back behind the tooth edge, and a tooth bottom between the tooth face on each tooth and the tooth back on a next tooth in front of said each tooth, and tooth gullets, wherein a tooth gullet (G1, G2) is defined as a space between the tooth edges of two adjacent teeth, said saw blade having two planar sides; a right hand side (R) and a left hand side (L) when the saw blade is viewed obliquely from above in the direction of sawing, wherein said tooth edge (E1, E2) extends between a right hand tooth corner (A1, A2) and a left hand tooth corner (B1, B2) with reference to said viewing direction, comprising the saw blade within a region of a first tooth gullet between the tooth edge (E1) of a first tooth (T1) and the tooth edge (E2) of the next tooth (T2) in front of said first tooth is beveled such that a saw blade surface (S1) within said region slopes towards the left hand side (L) of the saw blade forming an angle (&bgr;) with said left hand side, a beveled region with a sloping surface (S1) extending from a first tooth edge (E1) in a rear end of the first tooth gullet to at least a beveled tooth bottom (J1), said region being bordered to the right by a first line (K1) which extends from a rear foot point defined by the right hand tooth corner (A1) on the first tooth edge (E1) to a front foot point (C) which borders on the right hand side of the saw blade in the region of the first tooth gullet, to the left of the border line against the left planar side (L) of the saw blade, and forwards by said first line and/or by the tooth edge (E2) of said next tooth (T2) when the front foot point of said first line lies on said next tooth edge; that the saw blade, within a region of a second tooth gullet (G2) between a second tooth and a next tooth in front of said second tooth is beveled in the same way as in the first tooth gullet but instead to the right, and that the saw blade within the region of first and second tooth gullets between first or second teeth, on one hand, and teeth in front thereof, on the other hand, along a length of the saw blade are beveled in a mode alternating to the left and to the right in said first and second tooth gullets, the first tooth (T1) having a left beveled region that is beveled from the right hand side (R) down to the left hand side (L), the left beveled region extending from the tooth edge (E1) down a tooth face (F1) across the beveled tooth bottom (J1) so that the angle (&bgr;) is formed relative to a horizontal plane (H).
