Iscar 2800739 Grooving Toolholder External Right Hand

Product Description

The ISCAR 2800739 is an external, right-hand indexable grooving toolholder in the Cut Grip series, designed for precision grooving operations on CNC lathes and turning centers. It features a GHD-style toolholder body with a clamp-style insert holding method, accepting GI-series inserts across a wide range of groove widths from 0.197 inches minimum to 0.252 inches maximum. Maximum depth of cut is 0.5 inches. The shank measures 1 inch by 1 inch with a shank length of 4.8 inches and an overall length of 6 inches. This toolholder is suited for use across universal workpiece materials and is installed by machinists and CNC tooling technicians in production and job-shop environments.

The ISCAR 2800739 is intended for external grooving applications on a variety of workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and hardened materials. The multi-use design accommodates a broad family of GI-series inserts, making it adaptable across multiple grooving and profiling operations without changing the toolholder. The head length is 1.2 inches and the back-of-bar to cutting edge dimension is 0.92 inches, supporting close-clearance setups on turning machines.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and all power is isolated before mounting or adjusting the toolholder. Seat the toolholder securely in the turret or tool block using the appropriate fastener torque per machine manufacturer specifications. Verify insert seating and clamp engagement before returning the machine to operation.
