Product Description

The ISCAR 3600342 is a right-hand MDJN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built from steel, it features a negative rake angle of -6 to -7 degrees and accepts DN..43. series inserts, including the DNMG432-GN. The shank measures 0.75 inches square, and the overall length is 4.5 inches. This toolholder is part of the Isoturn series and conforms to ISO 13399 standards for cutting tool data representation. It is installed and set up by machinists and CNC operators in production and job-shop environments.

The 3600342 is suited for right-hand cutting direction on ferrous and non-ferrous workpieces in typical turning applications. Its MDJN toolholder style provides a 3-degree lead angle, making it appropriate for general-purpose turning, facing, and profiling passes. The compatible insert designation is DN..43., with the DNMG432-GN listed as a directly compatible insert size code. This toolholder fits standard square-shank tool blocks and turrets commonly found on small to mid-size CNC turning centers and engine lathes.
