Accupro 07072531 External Grooving Toolholder Left Hand

Product Description

The ACCUPRO 07072531 is a left-hand external grooving toolholder designed for indexable insert grooving operations on CNC lathes and turning centers. Built to accept a size 6 insert with screw-style clamping, it delivers a maximum depth of cut of 0.9853 inches and a minimum groove width of 0.2362 inches. The toolholder follows the GMEL style and is constructed from steel for durability under interrupted-cut and continuous grooving conditions. It is part of the CI series and is intended for use by machinists and CNC operators performing external grooving, parting, and profile turning on metal workpieces.

This toolholder is suited for external grooving applications in production and job-shop environments. The left-hand orientation makes it appropriate for specific spindle rotation and approach-direction requirements on turning centers. With a shank height of 0.750 inches and an overall length of 5 inches, it fits standard toolpost and turret configurations commonly found in mid-size CNC lathes. The screw-clamping insert retention method provides reliable insert indexing and consistent edge positioning during high-repeatability grooving cycles.
