Concrete Core Cutting & Diamond Drilling — Complete Guide

What is Concrete Core Cutting?

Concrete core cutting (or core drilling) is a precision engineering technique using diamond-tipped cylindrical drill bits to create clean, circular openings in concrete structures.

Applications

• Plumbing penetrations — holes for pipes through floors and walls
• Electrical conduit — routing cables through slabs
• HVAC ductwork — penetrations for ventilation
• Structural testing — core samples for strength analysis
• Drainage openings — floor drains and waste pipes

Core Sizes and Diameters

| Diameter | Typical Application | |----------|-------------------| | 25-50mm | Electrical conduit, small pipes | | 75-100mm | Drain pipes, waste pipes | | 100-150mm | Soil pipes, ventilation | | 150-300mm | Utility penetrations, manholes | | 300-600mm | Large openings, structural testing |

Advantages of Diamond Core Cutting

1. Precision: Clean, accurate holes
2. Low noise: Less noise than percussion drilling
3. No vibration: Non-percussive
4. No dust: Water-cooled bits
5. No spalling: Clean cutting edge
6. Reinforcement cutting: Cuts through rebar
