Hertel 1000205 Mwln Indexable Turning Toolholder 3/4 in

Product Description

The HERTEL 1000205 is a right-hand MWLN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. It features a negative rake geometry at -5 degrees, which promotes stronger cutting edges and is well suited for interrupted cuts and harder workpiece materials. The 3/4 inch by 3/4 inch square shank provides rigid setup in standard tool blocks and turrets. The toolholder accepts WN..33. series inserts and uses a clamp and screw insert holding method for secure, repeatable edge indexing. Licensed machinists and CNC lathe operators working in production or job shop environments are the primary installers of this toolholder.

This toolholder is appropriate for general-purpose external turning in both production and maintenance machining environments. The MWLN style is commonly applied when a 5-degree lead angle is needed to reduce radial cutting forces or to machine workpieces with features that require a specific approach angle. It is suited for use with standard-height square shank tool blocks on OD turning setups where rigidity and consistent insert indexing are priorities.

Key Features

• Right-hand cut orientation for standard OD turning setups
• Negative rake at -5 degrees for stronger insert edges on demanding cuts
• Clamp and screw insert holding method for secure clamping and fast indexing
• Accepts WN..33. series inserts with a 3/8 inch inscribed circle
• Square 3/4 inch by 3/4 inch shank fits common tool blocks and turret stations
• Steel toolholder construction for durability under continuous cutting loads

Compatibility

Designed for use with WN..33. series indexable inserts (complete insert compatibility: WN.. 332) with a 3/8 inch inscribed circle. No coolant-through capability. Verify insert pocket and clamp compatibility before ordering inserts separately.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret or tool block is locked out before mounting or removing the toolholder. Torque the insert clamp screw to the insert manufacturer's specification using the appropriate Torx or hex key. Verify tool centerline height against the workpiece spindle centerline before taking a first cut.
