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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand external grooving toolholder in GMEL style, CI series\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.9853 inches for deep external groove work\u003c\/li\u003e\n\u003cli\u003eMinimum groove width of 0.1575 inches compatible with size 4 insert seat\u003c\/li\u003e\n\u003cli\u003eSteel toolholder body for high rigidity and long service life\u003c\/li\u003e\n\u003cli\u003eOverall length of 6 inches with 1.0000-inch shank height for standard turret mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with screw-clamped indexable grooving inserts at compatible insert size code 4.
