Machining Processes: Turning, Milling, and Drilling – Trimantec

The desired form of the material will determine what type of tools you’ll need for the job. 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.Tooling is available in a variety of materials. The most
