Abstract: A twist bit for drilling mortar and for optimizing dissipation of heat and dust created by the drilling. A shaft has a flute therein configured in a spiral configuration therealong leaving a flute land thereon also configured in a spiral configuration therealong, a tip, and a head including the tip and a portion of the flute land coextensive with the tip. Diamond dust is disposed only on the flute land and the head. To optimize the dissipation of the heat and the dust created by the drilling, the twist drill operates via a drill motor in a range of approximately 25,000 RPMs to approximately 26,000 RPMs. The flute has a width of approximately ¼? and the flute land has a width of approximately ¼? and a height of approximately 1/16?.

Abstract: An improvement to roll-forming baling machines of the type having a plurality of endless belts supported on belt rollers that extend between a pair of transversely opposite sidewalls. One or more notches are created in the outside edge of the pair of belts that travel adjacent the sidewalls of the baler machine. The notches act to provide a cleaning effect for the baling machine to remove crop material unincorporated into the forming bales from the areas which result in undesired accumulation of such crop material.
