Sparkfun MC Etcher - Diamond Drag Bit (Combo Pack)

The MC Etcher - Diamond Drag Bit Combo Pack is an exquisite tool for precision engraving on a wide range of materials, including composites, metals, and glass. With its diamond-coated, spring-loaded tip, it elegantly etches patterns without cutting like traditional endmills. Note that the spindle should remain off during use to avoid rotation. The product is conveniently packaged in a reusable storage tube.

The MC Etcher is versatile in its application, making it suitable for artists, hobbyists, and professionals alike. Whether you're crafting intricate designs on anodized metals or engraving detailed patterns on glass, this tool delivers exceptional results. With two tip options, the 90-degree tip excels at penetrating harder materials, while the 120-degree tip is ideal for creating wider lines on softer surfaces like fiberboard.

One of the standout features of this tool is its adaptability to different materials. From plastics like acrylic and polycarbonate to metals such as aluminum and stainless steel, the MC Etcher handles them all with finesse. It even works on glass, porcelain, ceramics, and stone tiles like granite and marble. However, be mindful that harder materials may cause more wear, so it's wise to test for the optimal toolpath density to prolong the tool's lifespan.

Generating toolpaths for the MC Etcher is straightforward. Utilize software like Carbide Create to craft contour and pocket toolpaths with a zero RPM setting. Alternatively, Carbide Create Pro offers the Engrave toolpath feature for both outline and fill toolpaths. For optimal performance, a starting feed rate of 152 cm/min and a plunge rate of 76 cm/min are recommended, with a cut depth of 0.38 mm.
