Hertel 1000202 Lh Mwln Indexable Turning Toolholder

Product Description

The HERTEL 1000202 is a left-hand MWLN-style indexable turning toolholder designed for negative-rake external turning operations on CNC lathes and manual turning centers. The holder features a 1 inch by 1 inch square shank and an overall length of 6 inches, providing a rigid setup for medium to heavy-duty stock removal. It accepts WN..33 style inserts secured by a clamp and screw holding method, giving machinists a reliable, repeatable insert-retention system. The -5-degree rake angle is suited for harder workpiece materials and interrupted cuts where a stronger cutting edge geometry is required. This toolholder is made from steel for durability in production environments.

This toolholder is intended for use in production machining, job shops, and maintenance turning operations where a left-hand approach angle is needed to clear part features or work from a specific side of the workpiece. The MWLN style provides a 5-degree lead angle, which helps direct cutting forces and manage chip flow during external diameter turning. It is appropriate for use on CNC turning centers and conventional lathes that accommodate a 1 inch square shank tool station.

Installation Notes

Installation is performed by a machinist or tool-crib technician familiar with lathe tooling setup. Before installing or indexing inserts, ensure the machine is powered down and the spindle is fully stopped. Seat the shank fully in the tool block or turret and tighten the clamping fasteners per the machine tool manufacturer's torque guidance. Verify insert seating and clamp engagement before resuming cutting operations.
