シングル送りとマルチ送りとは？その違いは？ | オーエスジー

Single feed is a pass type that threads one pitch in one lap, and is selected when the high quality of the screw is emphasized and the high hardness is supported.

Multi-feed is a pass type that threads flute length minutes of the tool in one lap, and is selected when machining efficiency is important.

* For single-point tools that screw up one pitch in one lap, multi-feed cannot be selected.
