Descriptions:
1. The carbide (tungsten steel) bottom cleaning bits are with sharp cutting edge, high hardness and long life, resulting in nice finishing on woody pieces after cutting.
2. Cuts all composition materials, plywood, hardwoods, and softwoods, chipboard, and MDF etc. Great for cleaning up dadoes and grooves. Cannot be used to cut ferrous metal and non wood materials. The larger the tool diameter, the smaller the spindle speed should be.
3. Use on hand held router, table router, edge trimmer, CNC and other automatic routers. Be sure to use only router bits and accessories designed for the router. The tool shank should be installed with a clamping depth of at least 1-inch to maintain the proper pressure carrying range.
4. Always choose a router bit with a longer cutting edge than the workpiece. For example, use a tool with 1-inch cutting edge length when milling grooves of 1/2-inch depth. (It is NOT recommended that the cutting edge length equal to or less than 1/2-inch).
