<p>A cutting tooth, viz. roughing tooth (2) and finishing tooth (3) made from cutting metal for a metal slitting saw, especially a circular disk saw, the geometry of said tooth being determined by the primary clearance angle ( alpha ), the rake angle ( gamma ), the radial clearance angle ( beta ), the tangential untoleranced dimension (s-e) and a tangential land (12) on the finishing tooth (3) with a negative relief angle ( epsilon ), in which for both the roughing tooth (2) and the finishing tooth (3) the cutting edge (7; 7', 7'') is stabilized by a negative land (5; 5', 5''), and in which the angle ( chi ) between land and chip breaker face (4) is about 190 DEG to 240 DEG , especially about 205 DEG to 230 DEG .</p> |
