The cermet-tipped finishing hob shows good results in economical and productive finishing of tooth surfaces. As the cermet finishing hob has poor grindability, it takes a long time to manufacture the cermet hobs and it is difficult to keep the hob tooth profile accurate. In this paper, small lands of zero relief angle are made on the cutting edges of the cermet finishing hob in order to manufacture a highly accurate hob. By finish hobbing tests with the cermet hobs having various land widths, the hob wear and the tooth surface roughness vs the width of lands are investigated. The hob with the small land width of about 0.1mm is superior in wear resistance and improvement of the tooth surface roughness to those with land width greater than 0.2mm.
