Embodiment Construction

[0032] Referring now to the figures, in which like numerals indicate like parts, and particularly to FIGS. 1 and 2, which are, respectively, a diagrammatic cross sectional view through the mortar showing the twist bit of the present invention drilling an axial hole in the mortar and optimizing dissipation of heat and dust created by the drilling, and, a diagrammatic cross sectional view through the mortar showing the twist bit of the present invention drilling and cutting a lateral hole in the mortar and optimizing dissipation of heat and dust created by the drilling, the twist bit of the present invention is shown generally at 10 for drilling holes 11 in mortar 12 via a drill motor 13 and for optimizing dissipation of heat 14 and dust 16 from the hole 11 created by the drilling.

[0033] The configuration of the twist bit 10 can best be seen in FIGS. 3 and 4, which are, respectively, a diagrammatic side elevational view of the twist bit of the present invention identified by ARROW 3 ...

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″.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention: [0002] The present invention relates to a twist bit for drilling mortar, a and more particularly, the present invention relates to a twist bit for drilling mortar and for optimizing dissipation of heat and dust created by the drilling. [0003] 2. Description of the Prior Art: [0004] Numerous innovations for drill bits have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention. [0005] A FIRST EXAMPLE, U.S. Pat. No. 3,692,127, Issued on Sep. 19, 1972, to Hampe et al. teaches an improved rotary diamond core bit offering longer life in dry and in chip flush drilling. Grade AAAA dodecahedron diamonds within the range of 18 to 22 diamonds per carat size, each having a select rectangular pyramid point region free of internal flaws and with an included angle of 100 degrees to 12...
