Collection: Diamond Core Drills

We have an extensive range of specialised drills to suit concrete, asphalt, hardstone, porcelain and ceramic tiles.

Our core drills range from 6mm to 250mm as standard stock, with larger sizes and customised barrel lengths available.

We believe we stock the best value core drills on the market. Spiral flushing is an awesome improvement, and combined with high spec positioned diamond - maximises cutting speed and flushing.

Fast flush = zenesis

Fits 52mm +, 1 1/4 UNC box thread

We believe the best value core drills on the market. Spiral flushing is an awesome improvement, and combined with the high spec positioned diamond - maximises cutting, speed and flushing.

Performance = non zenesis

Fits 16mm to 45mm, R 1/2 pin thread
Fits 52mm +, 1/4 UNC box thread

This is our popular core drill that we’ve been providing for ten years.

Above 50mm great budget option now they are being sold off as the spiral option is steadily replacing them.

Electroplated core drill

Fits standard drill chuck

Thin kerf electroplated core drills provide a thin clean cut, designed for granite and engineered stone.

It has a shorter life as a bonded product, and can only be used with water. The edge will wear quickly if used too dry and make the tool ineffective.

Long life sintered core drill 

Fits standard drill chuck

Long life sintered core drill suitable for concrete, hard stone, granite and tile.
