Using Tyrolit / Vincent CNC Tools to Engrave our Logo in Granite

In the video below, we go over the process of engraving our logo into Black Pearl granite using CNC tools by Vincent (formerly known as Tyrolit). We did this with our friend and partner, Dylan Mahurin, at Ultra Surfaces in Stockton, CA. We used his Park Industries TITAN CNC router to engrave, and programmed with file on AlphaCam.

We took an unorthodox approach for this project by engraving the majority of the large passes with Drainboard Grooving bit, and then filling in the small inside corners with tiny passes using a PCD Writing Bit.

The Single Pass Drainboard Grooving bit is a sintered diamond tool - multiple layers of diamonds impregnated inside the metal matrix - which is the most common type of cutting/grinding tool used in the stone industry. This tool is specifically designed for cutting drainboards into stone.

In contrast, we used a polycrystalline diamond (PCD) 60-degree angle writing bit by VINCENT for the fine corners in the logo. This tool has 10mm shank, therefore it requires an adapter to be used on a 1/2 GAS toll holder. Use with adapter TYR 34008608 (10mm to 1/2 gas adapter with grub skrew). Use this tool for your most fine and accurate engravings in stone. 

A PCD tool was more suitable for the finer touches, as it has a very fine point PCD is known for its exceptional hardness and wear resistance. A sintered diamond grooving bit is better for more bulky stock removal.
