Abstract

A twist bit (10) for drilling mortar (12) and for optimizing dissipation of heat and dust created by the drilling. A shaft (18) has a flute (22) therein configured in a spiral configuration therealong leaving a flute land (24) thereon also configured in a spiral configuration therealong, a tip (26) , and a head (28) including the tip and a portion of the flute land coextensive with the tip. Diamond dust (20) is disposed only on the flute land and the head. To optimize the dissipation of the heat (14) and the dust (14) 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 1/4' and the flute land has a width of approximately 1/4' and a height of approximately 1/16'.
