Review on JIUWU 6 35Mm 3 175Mm Engraving Router by Jacob Burns

I recently purchased a router bit for my industrial and scientific engraving needs. Based on my experience, it has worked well and saved me time during my projects .The bit fits comfortably with most machines, and the engraving on different materials is very precise. Plus I've used it for a few weeks now and haven't noticed any signs of wear and tear. The only downside I can see so far is that it only comes in two sizes..
