(0.625-18 mount) stock Core Drills are engineered to deliver clean, accurate holes in hard and brittle materials. Using our exclusive high-strength metal bond, diamond grit is held securely in place for steady cutting action. As a result, tool life is extended and performance stays consistent over time. These drills are available in sizes from 0.030″ to 0.200″ and come standard with a precision 0.625-18 threaded nut mount. When needed, custom mounting solutions can also be supplied.
For applications where hole quality matters most, these core drills are optimized for straight and smooth results. In practice, proper use helps reduce chipping, cracking, heat damage, and early tool failure. Because of this, they are widely used in production environments, prototyping, and research settings that demand repeatable results.
These metal bond diamond core drills are commonly used to drill:
Quartz and glass
Technical and piezoelectric ceramics
MACOR®
Sapphire
Silicon carbide and boron carbide
Silicon nitride and alumina
YAG
Beryllium
Composites, nitrides, minerals, and stone
Metal bond matrix for strong diamond retention and long tool life
Fine, medium, or coarse diamond grit options to control finish quality
Internal coolant channels to improve cooling and debris removal
Compatible with water or oil-based coolants
CNC-machined brass mounts for accurate, repeatable installation
Compared with many other bond types, these tools provide a longer usable life. In addition, they hold their shape and size through repeated drilling cycles. Most importantly, they cut materials that quickly wear out resin or plated tools while still producing clean, precise holes.
To meet specific needs, core drills can be custom-made for ID, OD, wall thickness, bond hardness, diamond grit, and mounting style.
Overall, these metal bond diamond core drills offer a reliable solution for precision drilling when durability, accuracy, and hole quality are essential.
