Vargus 66706 Indexable Threading Toolholder Internal Rh

Product Description

The VARGUS 66706 is an indexable threading toolholder designed for internal threading operations on lathes and turning centers. Built in the Mini L Series, this right-hand toolholder accepts a 5LKIR insert secured by a screw-clamp holding method, delivering consistent thread geometry and reliable insert retention during high-repetition threading cycles. The shank measures 0.49 inches in height by 0.5 inches in width, with an overall length of 3.19 inches and a neck diameter of 0.24 inches. The SNVRC toolholder style and coolant-through capability make this unit well suited for tight-bore internal threading applications where chip evacuation and heat management are critical.

This toolholder is intended for internal threading on CNC lathes and turning centers where small-bore access is required. The Mini L Series geometry is commonly used in precision machining environments handling parts with restricted bore diameters. The right-hand configuration and screw-held insert seat are standard in production threading operations across aerospace, automotive, and general metalworking shops. A licensed machinist or CNC setup technician is the typical installer and operator.

Key Features

Compatibility

Compatible with 5LKIR indexable threading inserts. Designed for use in internal threading applications on CNC lathes and turning centers requiring a 0.5-inch shank toolholder in the SNVRC style.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or changing toolholders. Confirm the insert is seated flush and the clamping screw is tightened to the insert manufacturer's specification before initiating a threading cycle. Verify coolant-through passages are clear and connected to the machine coolant supply before operation.
