For when standard engraving bits just won't cut it.
Every CNC user eventually discovers the same reality. When working in metal, the quality of the finished engraving is often determined by the cutter long before the machine reaches its limits.

Made of solid carbide, these engraving bits allow you to produce crisp features in brass, aluminum, copper, silver, gold, and other non-ferrous metals. Whether you're engraving a custom pendant, producing commemorative coins, marking machined components, or adding branding to finished products, the correct cutter geometry helps preserve the details that would otherwise be lost.

These solid carbide metal engraving bits are designed for projects where detail matters. Small text, maker's marks, logos, jewelry engravings, decorative borders, serial numbers, coins, and custom artwork all rely on clean geometry and controlled cutting to transfer fine details accurately into metal.

Specifications
