Iscar 3603312 Pcln Indexable Turning Toolholder

Product Description

The ISCAR 3603312 is a right-hand PCLN-style indexable turning toolholder designed for external turning operations on CNC lathes and turning centers. Part of the Heliturn series, it features a 1 inch by 1 inch square shank and an overall length of 6 inches. The toolholder uses a clamp-style insert holding method with a negative rake angle of -6 degrees, providing stable cutting performance on a wide range of workpiece materials. Coolant-through capability is built in to support high-efficiency machining and extended insert life. A licensed machinist or CNC lathe operator typically installs and configures this toolholder in production and job-shop environments.

This toolholder is suited for right-hand turning applications in both production and precision job-shop settings. It accepts CNMX-series inserts and is compatible with standard insert sizes including CNMX452-M4PW. The 1.3 inch head length and 1.25 inch back-of-bar to cutting edge dimension position it well for general-purpose external turning, facing, and profiling. It conforms to ISO 13399 standards, making it compatible with tool management and presetting software used in modern machine shops.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Secure the shank in the tool block per the machine tool builder specifications, and verify insert seating and clamp torque before resuming cutting. Coolant-through connections should be checked for proper alignment and sealing before operation.
