Core Drilling & Coring

Dust-free diamond core drilling for pipes, cabling, HVAC and drainage — any diameter, any depth. Stitch coring for large structural openings where a single core is not sufficient.

Precision holes, any size, any substrate

From a 50mm drainage core to a stitch-cored structural opening over a metre wide, Blitz drills it clean. Wet-cutting with dust suppression as standard — concrete, block, brick or stone.

  • All core diameters from 50mm up to 500mm+
  • Stitch coring for large openings — doors, windows, ducts
  • Hilti and WEKA K32 drill rigs for precise, vibration-controlled drilling
  • Wet cutting — zero airborne dust on site
