HOLE CUTTER WITH MINIMUM TOOTH PITCH TO BLADE BODY THICKNESS RATIO

摘要

A hole cutter for cutting a work piece, such as a wood and/or metal work piece, has a substantially cylindrical blade body defining a wall thickness within the range of about 0.032 inch to about 0.038 inch, and a cutting edge formed on one end of the blade body including a plurality of teeth defining an average tooth pitch within the range of about 3.5 TPI to about 5.5 TPI for cutting the work piece and forming chips therefrom. The substantially cylindrical blade body and cutting edge define an average tooth pitch to blade body thickness ratio of at least about 110.
