SMART CUT® Thin Wall Diamond Core Drill – Sintered (Metal Bond)

This SMART CUT® thin wall diamond core drill is engineered for precision drilling in hard, brittle, and abrasive non-metallic materials. Manufactured with a sintered metal bond diamond matrix, the drill provides excellent diamond retention, long tool life, and consistent cutting performance in demanding applications.

The thin wall design minimizes material loss while maintaining high rigidity and dimensional accuracy. The result is faster drilling, lower cutting forces, and reduced heat generation.
