The two basic types of cutting tools are single point and multi-point tools. Use single point tools for turning, boring, and planing. Use multi-point tools for milling and drilling. It is imperative to properly use and maintain the cutting tools for quality purposes. Unfortunately, proper upkeep of machinery and tooling is where it can get costly.ToolinSee more on trimantec
  • Milling (machining) Wikipedia

    Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
