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
