Iscar 2301939 Grooving Cutoff Toolholder Do-grip Right Hand

Product Description

The ISCAR 2301939 is an indexable grooving and cut-off toolholder from the Do-Grip series, designed for external turning operations on CNC lathes and machining centers. It accepts DG-style inserts held in place by a clamp mechanism, providing secure, repeatable positioning during grooving and parting operations. The toolholder features a 1 x 1 inch square shank and delivers a maximum depth of cut of 0.98 inches (24.89 mm) at a fixed groove width of 4 mm (0.1575 inches). It is a right-hand configuration with an overall length of 6 inches, suited for high-production turning environments where insert changeout speed and rigidity matter.

This toolholder is used in external grooving and cut-off applications in both production and job-shop turning operations. Typical installations include CNC lathe turrets and gang-tool setups where consistent groove geometry and insert repeatability are required. The Do-Grip series is a well-established ISCAR platform, and this holder is compatible with a range of DG-series insert geometries covering utility, corner, and radius-style profiles. It is installed and operated by machining professionals, CNC programmers, and toolroom technicians working with ferrous and non-ferrous materials.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle and turret must be fully powered down and locked out before mounting or removing the toolholder. Shank clamping should follow the machine tool manufacturer torque specifications for the turret style in use. Verify insert seating and clamp engagement before resuming cutting operations.
