I'm in the market for CNC tools specifically designed for cutting, engraving, and drilling applications with router machines. My work primarily involves hardwood and plastic boards that have a minimum thickness of 18mm. Therefore, I'm looking for high-quality tools that can efficiently handle these materials. The tool diameter I need falls between 6mm and 8mm. It's important that these tools provide precision and durability to ensure optimal performance while working with the specified boards. If you have options available, please provide details on the various types, materials, and pricing. Looking forward to your recommendations!
