| 256 | Core drill bits with enclosed fluid slots | US12909187 | 2010-10-21 | US08051929B2 | 2011-11-08 | K. Shayne Drivdahl; Michael D. Rupp |
| Core drill bits with long crown heights are described herein. The core drill bits have a series of slots or openings that are not located at the tip of the crown and are therefore enclosed in the body of the crown. The slots may be staggered and/or stepped throughout the crown. As the cutting portion of the drill bit erodes through normal use, the fluid/debris notches at the tip of the bit are eliminated. As the erosion progresses, the slots become exposed and then they function as fluid/debris ways. This configuration allows the crown height to be extended and lengthened without substantially reducing the structural integrity of the drill bit. | ||||||
