Discoverer® Plastic Core Blocks
These blocks are the modern plastic counterpart to the long‑established wooden core blocks. That’s all there is to it. Their etched top surface provides an ideal texture for writing with a permanent marker.
Wooden Core Blocks
Made with one flat and one angled surface, so they have the ability to fit into either round- or square-bottomed core trays. They come with a smooth-finished surface that is ideal for writing notes and drill hole information.
Wooden Core Blocks with Aluminum Tags
They can also be supplied with aluminum tags stapled onto them - this will provide the driller with writing or scribbling space to log core details with an indelible mark.
