What is an end mill that can process right-angle corners? Pinkad Right Angle

If there is an indication for a right-angle corner in the drawing, the end mill side must also be at a right angle. However, in the case of a typical carbide end mill, the corner is intentionally covered with a blade plate called "gash" that takes the corner of the end mill in order to suppress chipping . End mills with gashes at the corners are not at right angles, so they cannot process right-angle corners. On the other hand, the "Pincad" specification, which is a specification of an end mill with a sharp cutting edge and capable of right-angle machining, is considered to be ideal for machining accurate shapes, but inevitably increases the risk of cutting edge chipping during machining.

Therefore, we recommend the AE-VM series right-angle type.

The AE-VM right-angle type has a special blade pad (gash application) that suppresses scraping residue due to changes in the diameter of the cutting edge while providing chipping resistance, enabling highly efficient and accurate right-angle cornering.

For right-angle cornering of general steels such as mild steel and SUS, the AE-VM right-angle type is recommended.
In addition, the following series are recommended for right-angle cornering of non-ferrous materials.

・ Non-ferrous DLC carbide end mills AE-TS-N(-SP) (short), AE-TL-N(-SP) (long)

・ Non-ferrous carbide DLC end mill high-performance type AE-VTS-N(-SP)
