Kennametal 1600246 Indexable Grooving Toolholder Left Hand

Product Description

The KENNAMETAL 1600246 is a left-hand indexable grooving toolholder in the KGMS style, designed for use on CNC lathes and turning centers in metal-cutting operations. It uses a clamp-style insert holding method to secure indexable grooving inserts firmly during cutting. The shank measures 1.0000 inches in height and 4.2600 inches in length, with an overall length of 5.5 inches and a center-to-cutting-edge dimension of 0.5600 inches. This toolholder belongs to the A3 series and is built for precision grooving, parting, and related turning operations in production and job-shop environments.

This toolholder is suited for external grooving applications on metal lathes and turning centers in both production and repair shop settings. The left-hand orientation makes it appropriate for operations requiring a specific approach direction or machine configuration. It is typically installed and set up by machinists, toolroom technicians, or CNC programmers working in metalworking and machining environments where accurate groove geometry is required.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or adjusting the toolholder. Seat the shank securely in the toolpost or turret and verify the center-to-cutting-edge height against the machine centerline before beginning any cut. Always inspect the clamping mechanism and insert seating before operation.
