Accupro 07016561 External Grooving Toolholder Right Hand

Product Description

The ACCUPRO 07016561 is a right-hand indexable external grooving toolholder designed for precision grooving operations on CNC lathes and turning centers. Built in the GMER style with a steel shank, it accepts a size 4 insert secured by a screw-clamp holding method, providing rigid, repeatable positioning during interrupted cuts. The toolholder delivers a maximum depth of cut of 0.9853 inches and handles groove widths starting at 0.1575 inches. With an overall length of 5 inches and a shank height of 0.75 inches, it fits standard lathe turrets commonly found in production and job-shop environments. Machinists and toolroom professionals rely on this holder for external grooving, parting-adjacent operations, and profile work requiring consistent insert indexing.

This toolholder is suited for external grooving applications on ferrous and non-ferrous workpieces in both production turning and general machining environments. The CI series designation indicates compatibility with standard indexable grooving insert systems. It is intended for use by machining professionals operating manual or CNC turning equipment where controlled groove geometry and repeatable depth are required. The screw-clamp insert holding method is appropriate for moderate to high feed rates in external groove profiles.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's turret mounting specifications. Ensure the machine spindle is fully stopped and the turret is locked before mounting or removing the toolholder. Use the appropriate hex key to tighten the insert clamping screw to the insert manufacturer's recommended procedure; do not overtighten. Verify tool centerline height and overhang before taking a first cut.
