Kennametal 1121195 Clamp Stud Fix-perfect Indexable Tools

Product Description

The KENNAMETAL 1121195 is a clamp stud designed for use in the Fix-Perfect series of indexable turning and face/shell mill toolholders. This small but critical piece of hardware secures the cutting insert clamp to the toolholder body, maintaining precise insert positioning during machining operations. Weighing approximately 0.005 pounds, the 1121195 is a low-mass fastener that must be replaced when worn or damaged to preserve clamping integrity. Installation and replacement are typically performed by machinists, CNC setup technicians, and tool crib personnel responsible for indexable tooling maintenance.

This clamp stud is used in metalcutting environments where Fix-Perfect series toolholders are in service, including both face milling and turning applications. It is compatible with toolholder styles R311 and R313, as well as clamp-type hardware. Insert families 4.21103L and 4.21103R are among the compatible insert lines supported by toolholders that use this stud. It is sold individually but is subject to a minimum order quantity of 10 units, making it suitable for stocking in a tool crib or maintenance inventory rather than single-unit emergency sourcing.

Installation Notes

Clamp studs should be installed and torqued using the toolholder manufacturer's recommended driver to avoid stripping threads or damaging seating surfaces. Always index or replace the cutting insert with the machine powered down and the spindle locked per shop safety procedures. Inspect the stud for thread damage or deformation before reinstalling a clamp assembly. Worn or deformed studs should be replaced rather than reused, as a compromised stud can cause insert movement or ejection during cutting.
