CNC Stone Tools & Granite Fabrication Tooling | Basic Diamond

Precision starts with the right CNC stone tools. Basic Diamond stocks granite fabrication tooling for routers, bridge saws, and automated lines - including profile wheels for edge detailing, finger bits for inside corners, CNC-spec core bits, vacuum pods, and tool holders. Every piece is selected for production shop volume, not just occasional use.

If you're running a Brembana, Intermac, Comandulli, or similar machine, our tooling is sized and specified to fit standard spindle configurations. Also need router bits or inline and automatic tooling? Both are available in the same place. Free shipping on orders over $99.

Frequently Asked Questions

+

How do I know which profile wheel fits my CNC machine?

Profile wheel compatibility depends on spindle collet size (typically 20mm or 30mm) and the edge profile you're cutting. Common profiles include pencil round, 1/8" round, full bullnose, and ogee. If you're not sure, send us your machine make/model and edge profile - we can confirm the right fit.

+

What are finger bits used for in stone fabrication?

Finger bits are used for inside corners and curved cutouts - places a profile wheel can't reach. They're common for sink undermount cutouts and decorative edge transitions. They run at high RPM with water cooling.

Do your CNC core bits fit all machines?

Our CNC core bits come in standard collet sizes (20mm and 1-1/4" most common). Check your spindle collet spec before ordering. We stock both dry and wet-use CNC core bits depending on your machine setup.
