Can end mill be used as drill?

What-are-the-differences-between-end-mill-and-drill

End mills are used in many machining processes, which greatly improves the efficiency of workpiece processing. Many people wonder whether the end mill can be used as a drill because it is similar to the drill? As a supplier of carbide cutting tools, UKO is here to explain the difference between end mill and drill?

What are the characteristics of end mills?

  • Each tooth of end mill participates in intermittent cutting periodically.
  • The cutting thickness of each cutter tooth varies in the cutting process.
  • The feed rate of each tooth α f (mm / tooth) represents the relative displacement of the workpiece in the time when the end mill rotates one tooth.

What are the differences between end mill and drill?

Different uses

End mill is mainly used to process plane, step, groove, forming surface and cutting workpiece on milling machine, while drill is one of the important tools for oil drilling, which is generally used for drilling.

Different categories

End mill is generally divided into sharp tooth end mill and relieving tooth end mill; drill is divided into diamond bit, cone bit and scraper bit.

The posterior angle is different

End mill: the side edge of end mill has back angle, so it can be cut laterally.

Drill: the side edge of the drill has no back angle, so it can not be cut laterally. It is used for axial drilling.

So, can end mill be used as drill?

Generally, in order to ensure the machining efficiency and tool life, we will recommend different tools for different processing methods. For example, thread cutters are used to turn threads, drilling tools are used to drill holes, and milling tools are used for milling.

However, if there is no drill in some special cases, and we have a general single edge and double or three edge end mill passing through the center, it can also be used as a drill temporarily.
