Hertel 1000206 Mwln Indexable Turning Toolholder 3/4 in

Product Description

The HERTEL 1000206 is a right-hand MWLN-style indexable turning toolholder designed for negative rake applications on CNC lathes and manual turning centers. Built from steel, it accepts WN..43. series inserts secured by a clamp and screw holding method. The shank measures 3/4 inches wide by 3/4 inches tall, with an overall length of 4.5 inches. A -5-degree rake angle and 5-degree lead angle define the cutting geometry, making this holder well-suited for heavy interrupted cuts and hard materials where a negative rake insert provides edge strength and tool life advantages. Machinists and CNC programmers specify this holder when stable, repeatable insert seating is required.

This toolholder is intended for turning operations in both job shop and production environments. Its compact 4.5-inch overall length suits standard tool turrets on medium-sized CNC lathes. The 1.13-inch head length and 1-inch back-of-bar to cutting edge dimension support proper tool positioning without excessive overhang. Coolant-through is not supported on this holder, so external coolant delivery is standard practice. It fits applications where WN..43. (complete compatibility: WN.. 432) inserts are the shop standard, allowing insert inventory consolidation across multiple setups.

Key Features

• Right-hand cut orientation for standard OD turning setups
• Negative rake geometry at -5 degrees for strong insert edge support
• Clamp and screw insert holding for rigid, repeatable seating
• Steel construction for durability in production turning environments
• Accepts WN..43. inserts with a 1/2-inch inscribed circle
• Overall length of 4.5 inches with 3/4 inch square shank for standard toolpost and turret mounting

Compatibility

Designed for use with WN..43. series inserts (complete compatibility designation WN.. 432) featuring a 1/2-inch inscribed circle. Part of the Multi-Option series; manufacturer catalog references include MWLNR and L124B.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lockout the lathe or turning center before mounting or changing toolholders and inserts. Seat the shank fully in the toolpost or turret pocket and torque the clamping fasteners per the machine tool manufacturer specifications before taking a cut. Always inspect the insert pocket and clamping components for chips or wear before seating a new insert.
