Drill Deep – Drill Clean – Ideal for Through-Wall and Ducting Jobs
 
These Diamond Core Drill Bits are designed for clean, vibration-free coring through brick, block, concrete and masonry, even in delicate or finished areas
They use an abrasive diamond cutting edge (not hammer action), making them perfect for applications where a clean hole and minimal damage to surrounding material is key — like installing flues, extractor fans, or soil stacks

Available in 150mm and 300mm lengths, these cores are your go-to for full-depth wall, floor, and duct penetrations

⚠️ For faster, shallow-depth coring with hammer action, see our TCT Core Drill Range
