Kennametal 1132523 Torx Indexable Insert Screw

Product Description

The KENNAMETAL 1132523 is a Torx-drive clamping screw designed for indexable cutting tools. It secures replaceable inserts in place during milling operations, maintaining precise insert positioning under cutting loads. This hardware is part of the Fix-Perfect series and is matched to HPM-style toolholders used in face mill and shell mill applications. The screw's Torx drive interface allows controlled torque application during insert changes, reducing the risk of cam-out and fastener damage compared to hex drive designs. Licensed machinists and toolroom technicians working with indexable tooling systems are the primary users of this fastener.

This screw is applied in face mill and shell mill toolholder assemblies where indexable carbide inserts are clamped and periodically rotated or replaced. It is suited for production machining environments where insert changes occur at regular intervals. The Fix-Perfect series designation indicates compatibility within a specific Kennametal toolholder family requiring matched hardware. Correct screw selection is critical in indexable tooling - using a mismatched fastener can compromise insert seating and lead to runout or insert failure during cutting.

Key Features

• Torx drive interface reduces cam-out risk during insert changes
• Designed for HPM-style toolholder compatibility within the Fix-Perfect series
• Secures indexable inserts in face mill and shell mill configurations
• Minimum order quantity of 10 units supports stocking for high-frequency insert change operations
• Lightweight construction at approximately 0.0024 pounds per unit

Compatibility

Compatible with HPM-style toolholders accepting Fix-Perfect series hardware for face mill and shell mill indexable insert applications, as specified by the manufacturer. Verify toolholder documentation before ordering to confirm correct screw series and thread specification.

Installation Notes

Installation should be performed by qualified machinists or toolroom technicians familiar with indexable tooling systems. The toolholder must be secured and the machine must be fully powered down and locked out before performing insert changes or screw replacement. Use a calibrated Torx driver or torque wrench set to the toolholder manufacturer's specified torque value to avoid stripping the screw or over-clamping the insert. Inspect the screw threads and drive recess for wear before each reinstallation and replace worn hardware immediately.
