The triangle TCMT Turning Inserts are designed for STAC, STEC, STNC, and STUC holders. These high-quality inserts are essential for achieving precise and efficient cutting performance. Features: TiN Coated Inserts: Offer extended tool life and allow for higher cutting speeds compared to uncoated inserts. CVD Coated Inserts: Provide superior performance across all aspects compared to TiN coated inserts. Positive-Rake Design: Ensures the inserts have an edge less than 90° to sit flat in the holder, improving cutting clearance and resulting in a better finish. Single Cutting Edge: Each insert has cutting edges on one side, allowing for rotation within the holder when one edge becomes dull. Replaceable Edges: Larger nose angles and tip radii offer a stronger cutting edge but may increase vibration and result in a rougher finish.
