Accupro 07072044 External Grooving Toolholder Left Hand

Product Description

The ACCUPRO 07072044 is a left-hand indexable external grooving toolholder designed for precision grooving operations on CNC lathes and turning centers. Built to GMEL style in the CI series, it accepts screw-clamped indexable inserts at seat size 4, delivering a maximum depth of cut of 0.9853 inches and a minimum groove width of 0.1575 inches. The steel shank measures 0.75 inches in height and 5 inches in overall length, providing a rigid, stable platform for consistent groove geometry. Machinists and CNC operators use this holder for external grooving and cutoff applications where repeatable insert indexing and secure clamping matter.

This toolholder is suited for external grooving on workpieces machined in production turning environments. The left-hand orientation makes it appropriate for operations where the tool cuts toward the tailstock or where machine configuration requires a left-hand approach. The screw-clamp insert holding method allows fast, accurate insert changes without removing the holder from the turret. No coolant-through capability is provided, so coolant must be directed externally. Typical users include CNC machinists and tool-and-die shops running medium to high production turning schedules.

Compatibility

Designed for use with compatible size 4 indexable grooving inserts. Verify insert seat size and GMEL toolholder style match before ordering inserts.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down the machine and follow lockout/tagout procedures before mounting or removing the toolholder from the turret. Confirm shank dimensions match the turret pocket specifications before clamping. Torque the insert screw to the insert manufacturer's specification using the correct torx or hex key to prevent insert movement during cutting.
