Ingersoll Cutting Tools 4350818 Insert Screw

Product Description

The INGERSOLL CUTTING TOOLS 4350818 is an insert screw designed to secure indexable cutting inserts in compatible toolholders and milling or turning bodies. This hardware component provides the clamping force needed to hold inserts firmly in place during machining operations, resisting the cutting forces and vibration generated at the tool-workpiece interface. Weighing just 0.015 pounds, it is a compact fastener sized for indexable insert pockets. Machinists, tool crib technicians, and CNC setup personnel install and replace these screws as part of routine insert indexing and tooling maintenance.

Insert screws see daily use in machine shops running turning centers, milling machines, and boring operations that rely on indexable carbide or cermet inserts. When an insert screw strips, breaks, or goes missing, the affected toolholder is down until a replacement is installed. Stocking spare insert screws alongside insert inventory minimizes unplanned downtime. This part is sold individually, making it straightforward to order exact quantities needed for a toolroom or repair kit.

Key Features

• Designed to clamp indexable inserts securely within toolholder insert pockets
• Compact, lightweight construction at 0.015 pounds
• Sold as a single unit for precise quantity ordering
• UNSPSC Code 31161500 classified under industrial fastener hardware
• Compatible with insert-type hardware as specified by INGERSOLL tooling systems

Compatibility

Designed for use with indexable insert toolholders that accept insert screws as the clamping hardware. Confirm the thread size and drive style match the specific toolholder pocket specification before ordering.

Installation Notes

Insert screws should be installed and torqued using the correct Torx or hex key driver specified by the toolholder manufacturer - use of incorrect drivers risks cam-out and screw head damage. Always power down and lock out the machine spindle before indexing inserts or replacing insert screws. Do not over-tighten; follow the toolholder manufacturer's recommended seating procedure to avoid stripping the pocket threads. Replace any screw that shows signs of thread damage, deformation, or a damaged drive recess.
