The ACH-GB cuts pipe and concrete structures with a chain instead of a wheel, which is what buys plunge cuts to full bar depth, square corners without overcuts, and irregular openings a circular blade cannot follow. Underground utility contractors and municipal water departments run it on ductile iron main; the same saw with a concrete chain cuts walls, vaults, and reinforced concrete pipe.

Air drive is the safety story: no emissions where the saw runs, no kickback when the chain pinches, and the saw works submerged, so trench water is a cutting condition rather than a stop-work. The gearbox drive has few moving parts, cuts wet with no hazardous dust, and starts under load. Every configuration runs the same saw head, and the choices are concrete: bar length sets the depth at 16 or 20 inches; the fitted chain matches the material, concrete chain for concrete pipe and structures, PowerGrit for ductile iron, HDPE, PVC, and cast; and the Package adds the trench kit, from whip hose and oil through the pipe clamp that steadies bottom-up cuts. This is the pipe saw for crews that open mains in the ground and cut structure walls in the wet.

Common Applications

  • Cutting ductile iron, HDPE, PVC, and cast pipe on utility mains
  • Cutting concrete pipe, walls, vaults, and reinforced structures
  • Plunge cutting and square openings in confined and submerged conditions

Selection Notes

  • Pick the chain by material: Concrete chain for concrete pipe and structures, Ductile Iron (PowerGrit) chain for metal and plastic pipe; chains swap, so the other chain can be added later
  • Pick the bar by required depth: 16 in bar for cuts to 16 in, 20 in bar for cuts to 20 in
  • The Package configurations add whip hose, tool oil, wrench, storage bag, and a 10 in pipe clamp that reduces fatigue and steadies bottom-up cuts
  • Requires a 90 CFM at 90 PSI air source, the same band as the belly saws and HS hand saws
