USE:

Core drills are designed for economically enlarging cored, punched or drilled holes, removing up to 30% of the hole diameter.
The balanced cutting action of the core drill removes considerably more material than a reamer, often eliminating the need for a final reaming or boring operation.
For cast iron, non-ferrous metals, some steels, composites, plastics and non-metals.

OPTIONS

Intermediate metric sizes - see priced table below.
Special point angles.
