    Abstract: A drywall routing bit for cutting laterally in a drywall or sheetrock panel includes an elongated body terminating at one end in a tip for penetrating the panel. The bit includes a single helical flute which defines a cutting edge at a helix angle relative to said longitudinal axis of the bit of 36null-38null. The cutting edge of the flute is defined at a rake angle of 20null-26null. The fluted portion of the bit has a web thickness that is 60%-63% of the bit outer diameter, for a nullnull diameter bit. The tip of the bit includes angled chisel edges subtending an angle of 113null-123null and following a shallow S-shaped curvature relative to a plane including the subtended angle.

    Abstract: A cutting bit for a pruning tool includes an elongate body having a first end and a second end. At least one flute extends at least part of a distance between the first end and the second end of the elongate body. A shank is located at the first end of the elongate body and is adapted for connection to an associated pruning tool. The second end of the elongate body defines a boring tip.

    Abstract: A router guide assembly which permits rectilinear movement of a router for cutting acoustic tile panels while providing a reveal edge along the cut edges. Quick and easy movement is provided by two railed carriage sub assemblies, one of which is carried by the other. Manually activated mechanical stops are provided on each carriage for selectively preventing movement in either orthogonal direction so that a linear cut can be made in the other direction. Lock down devices are included for holding a tile in place. The assembly also includes a plastic housing and skirt attached to the underside of a router mounting plate for collecting and directing the sawdust resulting from the cutting of a tile to a location remote from the router guide assembly. Numerical measuring scales are selectively located on the assembly and include calibrations so that a required offset for bit size is automatically included when measuring for a particular cut.

    Abstract: An apparatus and method for cutting wallboards, such as gypsum wallboards or rock wallboards to an appropriate size and shape, and for locating utility boxes hidden behind a panelled wall and cutting of a section of the wall at the opening of the utility boxes. The apparatus of the invention comprises a portable hand tool having an adjustable rest for adjusting the depth of cut and a built-in ruler-guide arrangement permitting to cut parallel to a side of a wallboard or permitting to cut circles in a wallboard. The hand tool may be used in combination with a separate locator and cut-out template member positioned in utility boxes mounted behind an installed wall, which provides an indication of the location of each utility box by way of a wallboard puncturing prong, for cutting out an opening in the wallboard, following appropriate guide grooves in the face of the locator and cut-out template.

    Abstract: Apparatus for cutting through a standing tree near the base by advancing a power driven blade transversely through the tree trunk. The blade has a leading edge along which a motor driven cutting element is journalled and the element is a shaft provided with helical flutes and wood chipping edges. A tree tilting mechanism on the apparatus is operable to keep the kerf open behind the advancing element and to fall the severed tree to one side of the path of travel of the apparatus.
