Sandvik Coromant Coated Carbide Milling Insert, S30T Grade, PVD Coated, Square Shape, E-SL Chip Breaker, 14 Insert Size, 0.25" Thickness (Pack of 10)

CoroMill 690, developed specifically for high-productivity 2D profile milling of titanium components. CoroMill 690 is designed with end coolant providing the best chip evacuation when face and shoulder milling whether cavity or pocket milling. During cutting, the chips can be prone to sticking to the cutting edge. This means that the next cutter rotation is re-cutting the chip. By equipping every insert pocket with threaded coolant holes with nozzles for high pressure coolant delivery, you can apply maximum coolant where required. This effectively eliminates the problem for a constant cutting edge performance. Use for shoulder milling, edging/contouring, slotting, circular milling from a pre-drilled hole.

• Used with the Sandvik Coromant CoroMill 690 for light-machining long edge milling on titanium in average-to-good machining conditions
• S30T grade is a physical vapor deposition (PVD) coating of titanium aluminum nitride (TiAlN) over carbide that provides good wear resistance without limiting shock resistance, protects against micro-chipping, and maintains a strong edge, and performs well at high cutting speeds
• Light-machining (SL) chipbreaker helps prevent chip buildup
• Choice of side (P) or end (E) insert style
• Square shape has strong cutting edges
