Hole Openers

Fabricated Hole Openers utilize leg and cutter sections which are strategically mounted on an alloy center body assembly. They are manufactured with single or multiple stage cutting arrangements. Ample clearance is provided around the cutters to allow efficient removal of the cuttings. Replacement cutter sections can be welded into place to provide re-use of the body assembly. Available in sizes from 8" to 72" diameter.

Demountable hole openers with regular bearing cutters mounted in 3 or 4 point arrangement are also available upon request.

When ordering specify soft, medium, or hard formation. Cutters are available in milled tooth or tungsten carbide insert. When ordering give pilot hole size and top threaded connection for attachment to the drill string.
