Core drill for mechanical saddle D160/168mm

  Datasheet (PDF)

The core drill for mechanical saddles provides a specialized, high-precision cutting solution engineered specifically for executing lateral connections into external gravity sewer systems. Designated under product code FVE0366 with a nominal dimension of D160/168 mm, the tool creates exact circular cutouts in rigid PVC-U collector pipes to accommodate 90-degree mechanical branch saddles. The 168 mm cutting diameter matches the exact aperture requirement (dimension A = 168 mm) specified for installing DN160 saddle connections onto main sewer pipelines sized at D250 mm, D315 mm, D400 mm, and D500 mm. Operating via a toothed cylindrical hole saw assembly with a central pilot bit and drive arbor, the cutter smoothly penetrates both solid-wall (compact) and structured multilayer PVC-U pipe profiles without inducing delamination, thermal deformation, micro-cracking, or perimeter stress fractures. This precision cut ensures a clean edge profile and uniform concentric seating for the elastomer sealing element of the mechanical saddle, establishing absolute watertight tightness against external soil water infiltration and internal wastewater leakage. By delivering a dimensionally accurate penetration without relying on chemical adhesives or thermal fusion, the tool preserves the underlying annular ring stiffness and circumferential structural stability of the carrier pipe under soil backfill loads. The resulting clean, burr-free borehole prevents pipeline hydraulic disturbances and eliminates rogue debris from entering gravity sewer networks, ensuring rapid, consistent lateral tap-ins on active or greenfield utility infrastructure.
