Iscar 2301375 Grooving Cutoff Toolholder Left Hand

Product Description

The ISCAR 2301375 is an indexable grooving and cut-off toolholder in the Do-Grip series, designed for external turning operations on CNC lathes and turning centers. It accepts DG-series inserts held by a clamp mechanism and accommodates groove widths from 0.189 to 0.197 inches, with a maximum depth of cut of 1.5 inches. The left-hand configuration suits specific spindle orientations and machine setups where right-hand holders are not practical. The toolholder style is DGT and the shank measures 1 inch in height by 1 inch in width with an overall length of 6 inches. This holder is installed by machinists and CNC tooling technicians in production and job-shop environments.

The ISCAR 2301375 is used in external grooving and cut-off applications on metal workpieces in both production machining and job-shop turning operations. The Do-Grip series is widely applied in industries requiring precision groove geometry and clean parting cuts. The left-hand hand-of-holder designation makes this toolholder appropriate for machines with specific turret orientations or sub-spindle arrangements where standard right-hand tooling cannot be used. Compatible inserts span multiple DGN and DGR insert families, providing flexibility across a range of groove profiles and workpiece materials.

Installation Notes

This toolholder is installed by qualified machinists or CNC tooling technicians. Before mounting or indexing inserts, power down and lock out the machine spindle in accordance with facility lockout/tagout procedures. Torque the insert clamp screw using the manufacturer-supplied torque key only; do not use substitute tools that may strip the clamp mechanism. Verify shank seating and overhang length against the machine turret specifications before first use to avoid interference or chatter.
