Single-sided Without a Hole Triangular Milling Inserts
Adapt to Mitsubishi Insert
The single-sided without a hole triangular milling inserts are earlier products. The inserts are held in place by a pressure plate. The Japanese brand divides the 60-degree cutting edge into many specifications and styles. The specification of the cutting edge is determined by whether the surface needs to look bright to achieve a good cutting effect. However, due to the hole-free design, the insert will face many difficulties in the manufacturing process. Nowadays, this type of insert is more popular in the market as a secondhand insert.
Milling inserts have multiple cutting edges. After machining for a period of time, they can be turned to another corner and the insert can be replaced to extend the life of the insert. The machining conditions are high cutting depth and medium to low speed to achieve a high torque removal effect. The machined surface is mostly flat and slightly smooth with medium to high roughness. It is also suitable for machining many different materials, including metals, plastics, composites, etc. Generally, this type of blade has higher rigidity and stability to ensure cutting accuracy.
