    Security Standard Hole Openers Diamond Core Drill Bits For Enlargement Of Pilot Holes

    HOLE OPENERS

    Hole Openers Used for Enlargement of Pilot Holes and Large Hole Applications

    Security Standard Hole Openers are designed for enlargement of pilot holes, directional drilling and large hole applications



    ROSCHEN single stage hole opener is a simple but rugged design used for enlargement of pilot holes and large hole applications from 8 1/2″ to 56″. The body is machined from AISI 4145 fully heat treated alloy steel with arms welded onto the body providing location for the cutters. Arms and cutters are hardfaced for protection. The cutters are available in different designs for varying conditions and rock formations. The cutter assembly is a fully sealed unit incorporating ball & roller bearings. Retaining the whole assembly is achieved by a locking pin. The design of the hole opener enables quick overhauls on the rig site. Three or six replaceable nozzles are used giving optimum mud circulation around the cutters.

    Roschen offers Security Standard and Security Custom Hole Openers.
