Kennametal 1778220 Torx Cap Screw for Indexable Inserts

Product Description

The KENNAMETAL 1778220 is a Torx-drive cap screw designed to secure indexable cutting inserts in compatible toolholders and milling bodies. These screws are a consumable hardware component used in CNC machining, turning, and milling operations where indexable insert tooling is employed. The Torx drive design provides positive engagement with the bit, reducing the risk of cam-out during tightening. Each screw is manufactured to the dimensional tolerances required for reliable insert clamping and repeatable positioning. The package contains 10 screws, sold with a minimum order quantity of 1 package, making it practical to stock spares at the machine or in the tool crib.

This cap screw is intended for use in metalworking and machining environments, specifically wherever KENNAMETAL indexable insert toolholders require insert retention hardware. Typical install scenarios include lathe turning stations, milling machines, and boring applications where inserts are rotated or replaced during a production run. Maintenance machinists, toolroom technicians, and CNC setup personnel are the primary users. Keeping replacement cap screws on hand minimizes downtime when screws are stripped or lost during insert changes.

Installation Notes

Installation and replacement of indexable insert cap screws should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before changing inserts or insert hardware. Use the correct size Torx key or bit driver to avoid stripping the screw head. Do not reuse visibly damaged or deformed screws, as proper insert seating depends on the integrity of the clamping hardware.
