To provide a tip saw capable of having a long life without flying chips off because of the load during cutting while a rake face has a PCD or other polycrystalline sintered layer and right and left side cutting edges are provided with a positive side rake angle.

The tip saw 1 includes saw-toothed blade bases 3 formed at a predetermined pitch in a circumferential direction on an outer circumference of a disc-shaped base metal 2, with a tip 4 jointed to each blade base 3, wherein the tip 4 is composed of one ultra-high-pressure-sintered compact with a polycrystalline sintered layer 6 formed on cemented carbide base material 5, and is jointed to each blade base 3 while a rake face 8 includes the polycrystalline sintered layer 6 of the tip 4 and right and left side cutting edges 7a, 7b are provided with a positive side-rake angle δ1 so as to form a recess in the rake face 8.
