<p><P>PROBLEM TO BE SOLVED: To provide a saw blade with gaps hardly clogged with chips or dusts. <P>SOLUTION: A saw blade (100) has a plurality of teeth (104) with each tooth formed by a beveled leading face (120), a beveled trailing face (122) and a chamfered surface (124) located on the trailing face of each tooth. The trailing and leading faces (122, 120) are beveled in opposite directions in alternate order throughout the saw blade (100) prior to the forming of the chamfered surface (124). The beveled leading face (120) of each tooth intersects the chamfered surface on the trailing face (122) of each tooth to form a curved cutting edge (130) having a negative rake angle. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
