摘要： A hole saw having a blade portion separable into two parts which when separated form a base portion and a tip portion. The base and the tip have correspondingly shaped apertures and lugs that co-operate together to hold the blade tip in place. A locking means further assists in ensuring that the blade tip remains locked to the base and includes a sliding latch that engages an aperture in the blade and the base and is itself locked in place to thereby lock the blade to the base. An intermediate portion also allows for the hole saw to drill through different depths.

摘要： A rotary cutting tool fed along its axis of rotation is used for cutting processes in which teeth of the tool do not continuously engage a workpiece, such as forming a cope. A cylindrical body of the tool is fluteless in order to keep the tool's cutting swath to a minimum thickness and thus reduce the cutting forces and heat generation from those of conventional annular metal cutters. Circumferential spacing of teeth about an annular end face of the body acts to contain material removed from the workpiece until reaching a portion of the tool's rotational path in which the workpiece is not engaged, at which point the material is freed from the tool to prevent jamming. An outer surface of the cylindrical body is continuous over a substantial majority of its length in order to ensure adequate tool strength.

摘要： A cutter blade is provided having a cutting face. Formed in the cutting face are a plurality of spaced apart slots, each slot having forward and rearward sidewalls. A tooth is removably received in each of the slots, each tooth having a top surface extending above the cutting face and having forward and rearward sidewalls, The top surface of each tooth has a forward cutting edge and a rearward reduced height step section. A retention bar is provided for each tooth, each retention bar having a forward end that is received in the step section. A pin extending through an opening in each retention bar is threadably connected to the cutting face. By tightening the threaded pin the retention bar retains each tooth during cutting operation so that the tooth sidewalls frictionally engage the slot sidewalls and by unthreading the pin the retention bar may be rotated to permit removal and replacement of each of the teeth.
