Carmex KEUKIT External Threading Toolholder 16E Inserts

Product Description

The CARMEX KEUKIT is an indexable external threading toolholder designed for precision thread-cutting operations on CNC lathes and turning centers. Built around a 3/4 inch by 3/4 inch shank, it accepts 16E style indexable threading inserts and is classified as a CLRVVAL toolholder geometry. At 1.25 pounds, it provides the rigidity needed for consistent thread form and surface finish across production runs. This toolholder is the working interface between the machine turret and the cutting insert, and it is set up and maintained by machinists and CNC operators in metal fabrication and job shop environments.

The KEUKIT suits external threading applications where the toolholder mounts in a square shank turret position. It is appropriate for threading operations on ferrous and non-ferrous workpieces in both single-part and high-volume production settings. The CLRVVAL designation indicates the holder geometry and clearance angle configuration, which guides insert selection and determines the range of thread forms and pitches achievable. Machinists running standard metric or unified threading cycles will find this holder compatible with a wide range of 16E insert grades and coatings available from the manufacturer.

Key Features

• 3/4 inch by 3/4 inch square shank for common CNC turret and toolpost mounting
• Accepts 16E indexable threading inserts for external thread cutting
• CLRVVAL toolholder geometry for defined clearance and thread form accuracy
• Rigid one-piece steel construction supports consistent thread quality over extended production runs
• Weighs 1.25 pounds for straightforward handling during setup and changeover

Compatibility

Designed as an OEM-style indexable threading toolholder for use with 16E series threading inserts in external turning and threading applications on CNC lathes equipped with a square shank turret position.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before mounting or removing the toolholder from the turret. Ensure the shank seating surfaces are clean and free of chips before tightening. Follow the machine tool manufacturer torque specifications for turret clamping bolts, and verify tool offset and thread depth settings before running the first part.
