✔ Vermeer hole openers feature cutters that are new and purpose-built for this application. You will not find “split bits” (i.e., surplus or rebuilt cutters harvested from tricone pilot bits) on the Vermeer roller cone hole opener lineup.
✔ A special machine-after-weld manufacturing process helps with a proper gauge cut. Mating two machined surfaces (cutter and body) helps with concentricity of the tool, lending to equal loading on the cutters for even wear throughout the tool’s life.
✔ Cutters feature metal-faced seals rather than the conventional rubber O-rings. Like those trusted on the lower rollers of dozer track chains, metal-faced seals help maximize wear life in gritty conditions.
✔ Vermeer design maximizes cone size, helping increase maximum weight on bit and the rate of penetration for optimum penetration.
