摘要： A cutting tooth system includes a plurality of substrates, each having a base for attaching to the cutting wheel, and an outer surface opposite the base. A plurality of tooth pockets are integrally formed in the substrate, each tooth pocket having a tooth receiving aperture extending through the outer surface and into the substrate. A cutting tooth has a pocket engagement portion configured for being received in a mounting pocket. The pocket engagement portion defines a pocket engagement length and a shank defining a shank diameter. A cutter portion extends from the pocket engagement portion.

摘要： A drilling apparatus including a rotary cutting tool having a proximal end and a distal end and further defining a rotary axis generally extending between the proximal and distal ends. The rotary cutting tool includes a proximally directed face located between the proximal and distal ends that face mainly in a proximal direction. The rotary cutting tool also includes an angled mounting face that extends between the proximally directed face and the proximal end. The angled mounting face is angled relative to the proximally directed face and the rotary axis where one of a mounting aperture and a mounting protrusion are provided at the proximally directed face. The one of the mounting aperture and the mounting protrusion have a mounting depth that extends generally in the direction of the rotary axis. The distal end includes a feature that is configured for at least one of cutting and grinding.
