Vermeer adds replaceable wing PDC hole opener

This ground-up design joins the evergrowing line of rock-focused tooling from Vermeer

The replaceable wing PDC (polycrystalline diamond compact) hole opener has completed rigorous field tests and is now available fororder through Vermeer dealers and the BORESTORE® HDD tooling and accessories warehouse. This ground-up design joins the evergrowing line of rock-focused tooling from Vermeer, targeting consolidated rock formations less than 25,000 psi (1,700 bar). From a single 2.875-in API box x box body, contractors can interchange wing sets for cutting diameters of 8 in (200 mm), 10 in (250 mm) and 12 in (300 mm). With the ability to change sizes, users can maximise their investment in the single body. According to Jason Zylstra, Vermeer lifecycle product manager, having replaceable wings can also help maximise efficiency in the field. “These wings are meant to be replaceable. In the event of a damaged wing, a single replacement wing can be installed on the jobsite.” he explained. “If a standard hole opener gets damaged, the entire tool is out of commission until it is repaired.”

Vermeer has sourced premium PDC inserts that, in an independent study, showed significantly better wear characteristics than the inserts commonly found in PDC pilot bits. “Each wing is designed with a row of carbide buttons strategically placed to help protect the stability of the PDC inserts.” explained Zylstra. The PDC insert pitch has been industry research-informed to optimise the balance rate of penetration and impact resistance. In the event of needing pushback during reaming, rotary back-out cutters have been welded to the backside of each wing.
