Abstract (en)
There is manufactured and provided at a reasonable cost a tipped saw using tips of an extra-high pressure sintered material such as PCD, for example, a hollow face tipped saw. The tipped saw has tips 12 fixed to the distal ends of saw teeth 14 respectively. The tips 12 are made of an extra-high pressure sintered material formed by building a polycrystalline sintered material layer 22 on a surface of a cemented carbide substrate 20. A pair of tips 12, 12 is juxtaposed such that the polycrystalline sintered layers 22 thereof locate substantially side by side and are joined together by means spot welding at the cemented carbide substrate 20. <IMAGE>
