INROCK® centralizers are designed specifically for HDD applications. The proper use of centralizers increases hole opening production rates and extends the life of cutters and hole opener bodies resulting in lower overall tooling costs.
Centralization in front of the hole opening assembly symmetrically aligns cutters in the center of the pilot hole against the rock face ensuring the cutters evenly engage the pilot bore providing a smooth round bore hole.
INROCK®'s tapered design guides the hole opening assembly through "tight spots." The wide single ring profile minimizes drill string rotary torque and drag. Cuttings build up is reduced while centralization effect is maximized.
