Iscar 3314630 Carbide Turning Insert Left Hand Isoturn

Product Description

The ISCAR 3314630 is a left-hand LNMX-style carbide turning insert from the Isoturn series, designed for precision turning operations across a range of workpiece materials. It carries a multi-layer PVD coating combining TiAlN, AlTiN, and TiN under ISCAR's proprietary SumoTec surface treatment, which promotes edge toughness and wear resistance at elevated cutting temperatures. The insert features a 1.6 mm (0.0630 inch) corner radius, an insert thickness of 13.40 mm (0.528 inch), and an insert length of 15.00 mm (0.591 inch). It conforms to ISO 13399 standards and is classified under ANSI and ISO insert code LNMX. Licensed machinists and CNC turning specialists install this insert in compatible toolholders for finishing and medium machining passes.

The 3314630 is suited for turning applications on steel (P), stainless steel (M), special and super alloys (S), and hardened materials (H). The HT chip breaker geometry supports both finishing and medium machining operations, providing effective chip control across these material groups. A maximum depth of cut of 8.00 mm (0.315 inch) covers a broad range of turning passes. This insert is intended for use in production turning environments, including CNC lathes and turning centers where consistent surface finish and tool life are priorities.

• Left-hand insert orientation with negative side clearance and positive rake for controlled cutting action
• HT chip breaker supports finishing and medium machining operations
• 1.6 mm corner radius for a balance of edge strength and surface finish quality
• Maximum depth of cut of 8.00 mm (0.315 inch)
• Conforms to ISO 13399 insert identification standards

Compatibility

Designed for use in LNMX-style turning toolholders within the ISCAR Isoturn series. Compatible workpiece materials include steel (P), stainless steel (M), special and super alloys (S), and hardened materials (H) as defined by ISO primary workpiece material classifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or clamping key specified by the toolholder manufacturer to secure the insert at the proper clamping force — do not overtighten by hand estimation. Verify insert orientation (left-hand) and chip breaker position match the programmed toolpath before resuming operation.
