Professional CNC Bits for Stone Marble, Granite, Quartz & Other Stone Fabrication

Stone Tech Inc offers a range of CNC bits and diamond CNC tooling for professional stone processing applications. CNC tooling is an essential part of modern stone fabrication, allowing manufacturers and fabricators to achieve accurate cutting, profiling, carving, shaping and finishing of complex stone components.

Our CNC bits for stone are suitable for CNC routers and stone processing machines used with materials such as marble, granite, quartz, engineered stone, limestone, travertine and other natural and engineered materials. Different tool profiles and diamond configurations can be selected according to the material being machined, machine specifications and desired finish.

CNC Router Bits for Stone Fabrication

The right CNC router bit can make a significant difference in machining efficiency, tool life and surface quality. Stone Tech Inc supplies tooling suitable for applications including:

Stone cutting and slotting
Edge profiling and shaping
Marble and granite carving
Stone engraving
Sink cutouts and openings
Countertop fabrication
Architectural stone processing
3D stone carving
Decorative stone machining
Surface and edge finishing

Our CNC tooling range can include diamond CNC bits, profiling tools, carving bits, ball nose bits, tapered bits and specialized router tooling, depending on the requirements of the application.

CNC Bits for Marble, Granite & Quartz

Different stone materials require different tooling characteristics. Marble CNC bits are commonly selected for detailed carving, profiling and shaping, while granite CNC tooling requires tooling capable of handling a harder and more abrasive material. Quartz and engineered stone CNC bits are selected according to the composition of the material and the required cutting or finishing application.

Selecting the correct diamond CNC router bit involves considering factors such as the material, machine spindle, RPM, feed rate, tool diameter, shank size, cutting depth and required surface finish.

Choose the Right Stone CNC Tool

When selecting CNC bits, always match the tooling to your machine and application. Important specifications may include shank diameter, tool diameter, diamond segment configuration, working length, overall length and cutting profile.

If you are unsure which CNC bit is suitable for your stone processing application, Stone Tech Inc can help you identify the appropriate tooling based on your CNC machine, material and machining requirement.
