Kennametal 1953351 Internal Grooving Toolholder Right Hand

Product Description

The KENNAMETAL 1953351 is an indexable internal grooving toolholder designed for precision grooving operations on CNC lathes and turning centers. Built to A4E toolholder style standards, it accommodates A4 series inserts with a seat size of 5 and uses a clamp-style insert holding method for secure, repeatable positioning. The toolholder is manufactured from steel and features through-coolant capability, directing fluid directly to the cutting zone to extend insert life and improve chip evacuation during deep internal grooving. With a maximum depth of cut of 0.63 inches and an overall length of 12 inches, this right-hand holder is suited for demanding production environments where consistency and rigidity are required.

This toolholder is configured for internal grooving applications where access to bores and internal features is required. It requires a minimum hole diameter of 2.047 inches and supports boring depths up to 3.15 inches, making it appropriate for medium to large-bore turning work. The multi-use designation indicates it can handle a range of grooving tasks within compatible setups. It is typically installed by machinists and toolroom technicians working on production lathes in manufacturing, aerospace, oil and gas, and general metalworking environments. Compatible inserts follow the A4..05.. designation.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician familiar with indexable turning toolholder systems. Power down and lock out the machine spindle before mounting or adjusting the toolholder. Verify coolant line connections are secure and free of leaks before resuming operation. Confirm insert seating and clamp torque per the machine tool and toolholder manufacturer guidelines before taking a cut.
