Kennametal 1749718 Indexable Insert Clamping Screw

Product Description

The KENNAMETAL 1749718 is a clamping screw designed for indexable cutting tool assemblies used in milling and turning applications. This hardware secures indexable inserts to their toolholders, maintaining precise insert positioning under the cutting forces and vibration typical of metal removal operations. Weighing approximately 0.0044 pounds, the screw is a small but critical component — a loose or failed clamp screw can result in insert ejection, part damage, or toolholder damage. Licensed machinists, CNC operators, and toolroom technicians keep these on hand as routine consumable hardware.

This screw is suited for indexable toolholder assemblies used in both milling and turning setups. It is compatible with clamp-style insert retention systems where a drive screw threads into the toolholder body to lock the insert in its pocket. Typical installations include turning centers, CNC lathes, vertical and horizontal machining centers, and manual turret lathes running indexable carbide or cermet inserts.

Key Features

• Designed for clamp-style indexable insert retention in milling and turning toolholders
• Lightweight at 0.0044 pounds — standard consumable hardware format
• UNSPSC Code 31161500 for procurement and catalog classification
• Single-piece packaging suitable for individual replacement or bulk restocking

Compatibility

Designed for use with clamp-style indexable toolholders in milling and turning applications. Specific toolholder compatibility should be verified against KENNAMETAL toolholder documentation before ordering.

Installation Notes

Clamping screws for indexable toolholders are typically installed and replaced by machinists or toolroom technicians. Before replacing a clamp screw, ensure the machine is powered down, the spindle is locked, and all stored energy is released. Use the correct Torx or hex key drive as specified by the toolholder manufacturer — overtightening can strip the screw or crack the insert, and undertightening allows insert movement during the cut. Replace clamping screws at the first sign of thread damage or drive recess wear.
