Kennametal 1097247 Threading Toolholder Left Hand 0.5in

Product Description

The KENNAMETAL 1097247 is a Left Hand indexable threading toolholder in the Top Notch series, designed for both internal and external thread-cutting operations on CNC lathes and manual turning centers. Built on a square shank measuring 0.5 inches wide by 0.5 inches tall, the toolholder accepts N.2R inserts secured by a clamp-style holding method. With an overall length of 3.5 inches and a maximum depth of cut of 0.138 inches, this holder is suited for threading and grooving applications where a compact, reliable interface is required. Licensed machinists and tool-and-die technicians will find this a direct-fit replacement for Top Notch-compatible setups.

The 1097247 is appropriate for light-to-medium turning operations in both production and job-shop environments. Its multi-use designation covers both grooving and threading passes in a single setup, reducing tool changes on tight-tolerance threading work. The back-of-bar to cutting edge distance measures 0.75 inches, which determines positioning in the tool post or turret. This holder is used across residential-grade and commercial machining scenarios where the Top Notch system is already in use.

Key Features

• Handles both internal and external threading and grooving from a single holder body
• Left Hand orientation for specific spindle direction and approach requirements
• NE-style toolholder with clamp-style N.2R insert retention for positive, repeatable edge location
• 0.5 x 0.5 inch square shank fits standard tool posts and turret stations designed for that bore size
• Maximum depth of cut of 0.138 inches limits aggressive passes and protects insert seating
• No coolant-through feature — external coolant delivery required for wet cutting applications

Compatibility

Designed for use with N.2R series inserts in the Top Notch toolholder system. Compatible with tool posts and turret stations that accept a 0.5 x 0.5 inch square shank. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Power down and lock out the lathe or turning center before seating or removing the toolholder from the turret or tool post. Ensure the shank seating surfaces are clean and free of chips before clamping. Insert seating and clamping torque should follow the toolholder manufacturer specifications included with the insert and holder documentation.
