Downhole Directional Drilling Tools: Melfred Borzall Ogre

The Ogre stacked plate reamer is made for hard soil conditions including shale, sandstone, caliches and cobbles.

Each cutter takes off only ¼ inch more soil than the previous stage for smooth, efficient cutting action. The angled jets shoot water opposite the reamer, pushing loose material out of the bore direction.

Combined with a slow taper and deep-spiraled fluting, the Ogre produces maximum mixing and pumping. Curved backup blades make pushbacks a snap and hardfacing on all wear areas, including conical carbide blocks in front, make this one long lasting reamer.

Made for large capacity rigs, the Ogre starts at 14 inches on a 3.5-inch shaft with larger sizes available. 800.558.7500,
