Iscar 2801373 Grooving Toolholder Left Hand 3/4 Inch

Product Description

The ISCAR 2801373 is an external, left-hand indexable grooving toolholder in the Modular Grip series, designed for non-face grooving operations on CNC lathes and turning centers. It features a 3/4 x 3/4 inch square shank, an overall length of 5.6 inches, and uses a clamp-style insert holding method for secure, repeatable edge location. The MAH-style toolholder body conforms to ISO 13399 standards and is built for left-hand cutting direction applications where consistent groove geometry and insert indexability are required. Machining professionals and CNC setup technicians are the primary users of this toolholder.

This toolholder is suited for external grooving work on production turning equipment where a 3/4 inch shank size is appropriate. It is configured for left-hand cutting direction, making it the correct choice for applications where tool approach, turret orientation, or spindle rotation requires a left-hand setup. The clamp-style insert retention provides solid holding force during interrupted cuts and medium-duty grooving passes. It is a non-coolant-through design, so coolant delivery must come from an external source if required by the application.

Compatibility

Designed as an OEM-style replacement and standard fitment external grooving toolholder for CNC turning centers and manual lathes accepting a 3/4 inch square shank. Compatible insert style is designated by the MAHL19 toolholder series specification; refer to ISCAR insert compatibility charts for matching groove inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the toolholder from the turret or tool post. Verify shank seating depth and cutting edge height alignment to centerline before taking a first pass. Torque all clamping fasteners to the machine or toolblock manufacturer specifications only.
