Iscar 3600686 Mwln Indexable Turning Toolholder

Product Description

The ISCAR 3600686 is a right-hand MWLN-style indexable turning toolholder from the Isoturn series, designed for external turning operations on CNC lathes and manual turning centers. Built with a 1 inch by 1 inch steel shank and an overall length of 6 inches, it accepts WN..43. series inserts and operates with a negative rake geometry. The head length measures 1.13 inches, and the back-of-bar to cutting edge distance is 1.25 inches. This toolholder is the standard choice for machinists and toolroom operators running right-hand cutting passes on metal workpieces.

Suited for production and job-shop turning applications, the 3600686 fits into standard MWLN toolholder pockets on square-shank tool blocks and quick-change turrets. Negative rake geometry makes it appropriate for interrupted cuts and harder workpiece materials where edge strength is a priority. Typical applications include OD turning of ferrous and non-ferrous metals in both light and moderate stock-removal scenarios. The Isoturn series designation indicates compatibility with ISCAR's broader indexable turning system platform.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank firmly in the tool block or turret station before operation and verify insert seating and clamping torque according to machine tool specifications. Power down and lock out the spindle before changing inserts or repositioning the toolholder. Follow the machine manufacturer's guidelines for tool projection and overhang limits to maintain rigidity and surface finish quality.
