The indispensable properties in finishing hobs with cemented carbide tips or titanium carbide tips are the toughness for prevention against chipping and breakage and the resistance to wear. In the previous report, it was clarified that a cermet, which consists of titanium carbide and titanium nitride, had a superior resistance to wear and chipping, and made the surfaces smooth n finishing hardened and tempered workpieces. In this report, a new cermet finishing hob is manufactured for a trial, with which hardened and tempered gears are hobbed for finishing. This new cermet has more excellent properties in toughness, thermal shock resistance and grindability than the cermet tested in the previous report. The performance of the cermet finishing hob is superior in wear resistance and the improvement of the tooth surface roughness to those of the cemented carbide finishing hob.
