Accupro 07072895 External Grooving Toolholder Left Hand

Product Description

The ACCUPRO 07072895 is a left-hand indexable external grooving toolholder designed for CNC lathes and turning centers. Built to GMEL style in the CI series, it accepts screw-clamped indexable inserts at seat size 6, delivering a maximum depth of cut of 0.9853 inches and a groove width of 0.2362 inches. The steel shank measures 1.0000 inches in height and 6 inches in overall length, giving the holder rigidity for consistent groove geometry in production turning environments. Machinists and CNC operators install this toolholder when external grooving, parting, or profile work is required on a workpiece OD.

This toolholder is suited for external grooving operations on production lathes and turning centers in both job-shop and high-volume manufacturing settings. The left-hand orientation positions the cutting edge for specific spindle rotation and approach directions, making it the correct choice where a right-hand holder would interfere with the part or machine configuration. It is compatible with size 6 grooving inserts held by a screw-clamp method, which supports quick insert indexing with minimal setup downtime.

Key Features

• Left-hand holder orientation for dedicated external grooving applications
• GMEL toolholder style in the CI series with screw-clamp insert retention
• Maximum depth of cut of 0.9853 inches (25 mm) for deep external grooves
• Groove width of 0.2362 inches (6 mm) fixed minimum and maximum
• Steel construction with 1.0000-inch shank height for rigidity under cutting loads
• No coolant-through design; suitable for flood or dry cutting with external coolant delivery

Compatibility

Designed for use with size 6 compatible indexable grooving inserts secured by screw-clamp method. Verify insert seat size and series compatibility before ordering replacement inserts.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the lathe or turning center before mounting or removing the toolholder from the turret. Secure the shank fully in the tool block to the manufacturer-specified seating depth to prevent overhang deflection. Confirm insert seating and screw torque per the insert manufacturer's guidelines before resuming cutting operations.
