Hole openers

Our workshop is able to manufacture Hole Openers with cutters in sizes from 6" (152 mm.) to 48" (1220 mm.) Our Hole Openers are manufactured with sealed bearing milled tooth or tungsten carbide insert cutters, according to the type of formation to drill. Drilling mud circulation for removal of cuttings is assured through the nozzles located under cutter shoulders. The number of cutters assembled on the hole opener depends on the diameter and the formation to be drilled. In order to make a perfectly vertical hole, it is advisable to use stabilizers that may be positioned along the string above or below the hole opener.

When ordering please specify:

  • pilot hole size
  • hole opener size
  • type of formation
  • top and bottom connection
