8-in (20-cm) Replaceable Wing PDC Hole Opener

✔ The Vermeer-designed and manufactured line of PDC (polycrystalline diamond compact) hole openers bring performance and reliability to consolidated rock bores.

✔ From a standard 2.875-in (2 7/8”) API box x box body, contractors can interchange wing sets for cutting diameters of 8 in (20 cm), 10 in (25 cm) and 12 in (30 cm). With the ability to change sizes, users can maximize their investment in the single body. And in the event of wing damage, a single replacement wing can be purchased and installed in the field, rather than taking the tool out of service for an extended repair period.

✔Vermeer has sourced premium PDC inserts. In an independent test, these inserts showed better wear characteristics than the inserts commonly found in PDC pilot bits.

✔Carbide buttons span the profile of the cutter to assist stabilization and extend wear life.

✔ The hardfaced shaft helps reduce hourglass-style wear common in rock applications.

✔ Designed with 25 threaded fluid nozzles with 10 optional plugs for customizable drilling fluid management.

✔ Welded on rotary backout cutters.

✔ Industry research-informed PDC insert pitch for optimized balance rate of penetration and impact resistance.
