Sumitomo Electric Hard Metal SEC-Sumi Dual Mill DMSW08000EL type (long shank type)

The compound arc-shaped cutting edge makes both small and large cuts compatible. High-efficiency machining with a maximum feed rate of 3.5 mm / t per blade is possible.
The insert is economical with 6 corners on both sides. Uses a 7mm thick with a sense of security.
Achieves good surface roughness without a wiper insert even in high feed machining with a feed rate of 2.0 mm / t or more per blade.
A small depth of cut controls cutting resistance in the direction of back component force. It suppresses chatter in machining with long tool protrusions and enables high efficiency.
High-efficiency roughing of flat surface cutting, corner cutting, side surface processing, grooving, hole expansion processing, inclination processing, and helical processing.
* The insert is not incorporated in the main body.
