Accupro 07016553 External Grooving Toolholder Left Hand

Product Description

The ACCUPRO 07016553 is a left-hand external grooving toolholder designed for indexable insert grooving operations on CNC lathes and turning centers. Built to the GMEL style in the CI series, it accepts screw-held indexable inserts at seat size 4. The toolholder features a 1.0000-inch square shank height and an overall length of 6 inches, providing rigid support during external grooving passes. Maximum depth of cut reaches 0.9853 inches, with a minimum groove width of 0.1575 inches. The steel construction delivers the rigidity needed for consistent, repeatable grooving on production turning applications.

This toolholder is suited for external grooving operations in both job-shop and production environments. It is a left-hand holder, making it appropriate for applications where tool approach direction or machine turret configuration requires a left-hand orientation. The GMEL-style body and screw-clamped insert seat provide secure insert retention during interrupted cuts and full-depth grooving passes. Machinists and CNC setup technicians working on bar, tube, or shaft stock will find this a direct-fit solution for external groove profiles.
