Kennametal 1114219 Grooving Insert KC730 Carbide Tin

Product Description

The KENNAMETAL 1114219 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and part-off operations on CNC lathes and turning centers. The insert carries a KC730 grade designation with a PVD-applied TiN coating, which supports extended tool life in a range of workpiece materials. The cutting width measures 0.125 inches (3.18 mm), the maximum depth of cut is 0.150 inches (3.81 mm), and the full-radius corner geometry has a radius of 0.063 inches (1.59 mm). This is a right-hand insert with a positive 10-degree rake angle and a K-style chip breaker. It is sold individually but must be ordered in multiples of five.

This insert is suited for turning applications across material grades C2, C3, and C4, which correspond to a broad range of ferrous and non-ferrous workpiece materials. The Top Notch series insert style is NR with an insert size designation of 3062, making it compatible with Top Notch toolholders designed for that insert profile. Typical install scenarios include production turning on manual or CNC lathes where consistent groove width and controlled chip evacuation are required. The K chip breaker geometry supports chip management in medium-depth grooving passes.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Power down and lock out the machine before seating or removing inserts. Use the correct torque wrench or clamping screw driver specified for the Top Notch toolholder to avoid over-torquing the clamping mechanism. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper contact and accurate cutting geometry.
