This router bit is a fantastic tool for industrial and scientific use. After I put it to the test, I found that it created precise and clean cuts through even the toughest materials such as tungsten .The bit is durable and long-lasting, making it a great investment for any business or DIY enthusiast. However, the only con I found was that it is a bit pricey compared to other router bits on the market. Overall, I highly recommend the VEVOR 3 175Mm Engraving Tungsten Milling for any serious cutting tool needs..
