Review on 🔩 High-quality HOZLY Titanium Carbide 3 Engraving Bit, 175mm x 0.5mm x 3mm by Trey Michaels

When I used these on a CNC mill at very slow plunge and feed speeds I had a couple of failures immediately after plunge. Those who didn't, however, lasted impressively long. I was able to cut .055" mother of pearl chips (multiple passes) and ebony with no problem. For such a thin bit and at such a price I am very satisfied.
