Diamond Drill Bits

Tapered inverted hollow

The hollow tip-shaped diamond drill bits are incredibly versatile tools suitable for carving, grinding, drilling and pre-forming both hard and soft materials such as glass, stones, ceramics, bone, and metals.

These drill bits are equipped with a 1-1/2" long mandrel shank, measuring 3/32" in diameter, making them compatible with various rotary tools like Foredom, Dremel (with a 3/32″ collet), or any flex shaft hand piece accepting a 3/32″ diameter shank. With ten different diameter sizes available, users have options to suit their specific carving, grinding, drilling needs.

The diamond grit on these bits is evenly electroplated onto steel, ensuring high-quality performance. The diamonds are securely locked into place, providing an aggressive grinding rate for efficient material removal.

For optimal use, it's recommended to lubricate these drill bits with clean water before and during the operation. This lubrication acts as a coolant, reducing heat and friction during grinding, thereby improving the tool's lifespan and performance.

These drill bits are invaluable for artisans, craftsmen, and professionals working across various industries. Their ability to effectively work on both hard and soft materials makes them essential for tasks ranging from jewelry making to glasswork, ceramics, and metalworking, offering precision and efficiency in shaping carving, grinding, and drilling applications.
