PSTW 6 Corner Shoulder Milling Cutter, Straight Shank Type

Product features and specifications

Basic specifications and features of the product

Double-sided 6-corner (90°) insert

• With a thickness that increases rigidity and a low resistance positive rake angle, it is resistant to chatter vibration and supports machining with long protrusions
• Economical front and back 3 corners (both sides 6 corners) specifications
• Achieves an excellent finished surface with a wiper edge
