I recently purchased an engraving tool for my industrial and scientific work and this tool is just what I was looking for! After trying this product, I found that the tungsten carbide tip provides precise and accurate markings. The small size of the tip also allowed me to create detailed designs effortlessly. The only downside is that it can be a bit fragile if used roughly, but with proper care, it works great .Overall, I highly recommend this engraving tool for any precision work..
