Iscar 2800077 Grooving Cutoff Toolholder Left Hand

Product Description

The ISCAR 2800077 is a left-hand indexable grooving and cutoff toolholder in the Cut Grip series, designed for external turning operations on CNC lathes and turning centers. It accepts a wide range of GI, GPV, and TIP series inserts secured by a clamp-style insert holding method. The toolholder handles groove widths from 0.016 to 0.125 inches with a maximum depth of cut of 0.32 inches. The shank measures 0.5 inches square by 3.47 inches in length, and the overall assembly length is 4.5 inches. It conforms to ISO 13399 tooling standards, making it compatible with modern tool management and presetting systems.

This toolholder is suited for external grooving and part cutoff applications on metalworking lathes in production shop and toolroom environments. It is typically installed by machinists and CNC setup technicians working with ferrous and non-ferrous workpieces. The left-hand orientation makes it appropriate for applications where conventional right-hand holders are not practical due to spindle direction, machine configuration, or part geometry. The 0.47-inch back-of-bar to cutting edge dimension and 1.03-inch head length support rigid, repeatable positioning at the cutting zone.

Key Features

• Left-hand holder orientation for external grooving and cutoff operations
• Clamp-style insert retention provides rigid, repeatable insert seating
• Accepts GI, GPV, and TIP series inserts across a broad range of insert size codes
• Groove width range of 0.016 to 0.125 inches accommodates narrow and standard grooves
• ISO 13399 compliant for use with digital tool management and presetting systems
• No coolant-through design; suitable for standard external flood or mist coolant delivery

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine powered off, spindle locked, and all axes at a safe position. The toolholder should be mounted securely in the turret or tool block using appropriate fasteners torqued per the machine tool builder specifications. Insert installation and replacement require the correct ISCAR torx or clamp key; refer to the ISCAR Cut Grip tooling catalog for insert seating and clamping procedure. Verify groove width, depth of cut, and insert overhang against the workpiece drawing before initiating any cut.
