A spoilboard router cutter is a type of cutting tool used in woodworking to flatten and plane a spoilboard. A spoilboard is a sacrificial board that is placed underneath the workpiece to protect the table or bed of the CNC router from damage during cutting. Over time, the spoilboard can become uneven or damaged, which can affect the accuracy of the CNC router.
A spoilboard router cutter is designed to mill a thin layer of material from the surface of the spoilboard, creating a flat and level surface. It features a large cutting diameter and multiple flutes for efficient material removal, and may have a straight or spiral design depending on the specific application.
Spoilboard router cutters can be made from a variety of materials, including high-speed steel, carbide, and diamond. They are available in a range of sizes and shapes to fit different CNC routers and applications.
When using a spoilboard router cutter, it's important to take proper safety precautions, such as wearing eye and ear protection and using a secure surface to hold the workpiece. It's also important to use the proper technique to ensure that the cut is consistent and even across the entire surface of the spoilboard. Proper maintenance and replacement of the spoilboard router cutter can help to ensure consistent and accurate results.
