Kennametal 1137713 Indexable Insert Clamp Sefas

Product Description

The KENNAMETAL 1137713 is an indexable insert clamp in the Series SEFAS line, designed to secure indexable cutting inserts in compatible toolholders during machining operations. This clamp applies consistent clamping force to hold inserts firmly in the insert pocket, reducing movement under cutting loads and maintaining dimensional consistency across the cut. It is a precision metalworking component installed by machinists and toolroom technicians on CNC and manual turning, milling, or boring setups. At 0.0022 pounds, the 1137713 is a lightweight component, but its fit and function are critical to toolholder performance and insert life.

The Series SEFAS clamp is suited for use in metalcutting environments where indexable toolholders are standard — including production turning centers, machining centers, and manual lathes in both job shop and high-volume manufacturing settings. It is installed as part of a toolholder assembly and is replaced during routine maintenance or when a clamp shows wear, deformation, or failure to seat the insert properly. Compatibility with specific clamp screws is required for correct assembly.

Compatibility

Compatible with clamp screws 360.650, 360.651, 360.652, and 360.653 as specified by the manufacturer. Intended for use in KENNAMETAL Series SEFAS indexable toolholder assemblies.

Installation Notes

Indexable insert clamps are installed and serviced by machinists or toolroom technicians. Before replacing a clamp, ensure the machine spindle is stopped, all motion has ceased, and the toolholder is removed from the turret or spindle where practical. Use the correct clamp screw from the compatible series — mismatched screws can result in improper seating and insert ejection under load. Inspect the insert pocket and seating surfaces for debris or damage before installing the new clamp.
