Abstract

Disclosed is a cutting tool with an asymmetric tooth form, and a method for making the same. Such tooth forms are useful for cutting tools such as band saw blades, circular saws, hacksaws and other saw type products. The tooth form of this invention can improve precision over prior art tooth forms by reducing manufacturing variability. The improved precision provides more consistent performance and a better quality of the cut surface. The non-symmetrical form ground tooth profiles cut designated chip profiles and thereby cut specific portions of the kerf much like a broaching application. This non-symmetrical ground tooth profile can alter the distribution of the downfeed cutting force allowing for more aggressive cutting or conversely, cutting at the desired rate with less downfeed pressure.
