Kennametal 1097237 Threading Toolholder External Left Hand

Product Description

The KENNAMETAL 1097237 is an indexable threading toolholder configured for external, left-hand cutting operations. It belongs to the Top Notch series and accepts N.3R inserts held in place by a clamp-style insert holding method. The shank measures 1 inch wide by 1 inch tall (25.4 x 25.4 mm) with an overall length of 6 inches (152.4 mm). This toolholder is designed for grooving and threading applications on CNC lathes and turning centers. Licensed machinists and toolroom technicians are the primary users. The head length is 0.75 inches (19.05 mm) and the maximum depth of cut is 0.21 inches (5.33 mm).

This toolholder is suited for external threading and grooving operations in production turning environments, including both job shop and production floor settings. Its left-hand orientation makes it appropriate for applications that require cutting away from the chuck or in configurations where a right-hand holder cannot access the workpiece geometry. It is flagged as a multi-use tool, supporting both grooving and threading with compatible Top Notch series N.3R inserts.

Key Features

• External, left-hand configuration for threading and grooving operations

Compatibility

Designed for use with N.3R inserts in the Top Notch series. Verify turret or tool post bore size accommodates a 1 inch (25.4 mm) square shank before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on CNC or manual turning equipment. Power down and lock out the machine before mounting or removing the toolholder. Secure the shank fully in the tool post or turret block to the recommended clamping depth to prevent deflection under cutting loads. Inspect the insert pocket and clamping surfaces for chips or debris before seating the N.3R insert.
