Kennametal 1099643 Indexable Insert Clamping Screw

Product Description

The KENNAMETAL 1099643 is a clamping screw designed to secure indexable inserts in compatible toolholders and cutting tool bodies. These small-format fasteners are a critical hardware component in indexable tooling systems, holding the cutting insert firmly in the pocket during turning, milling, or boring operations. A loose or damaged clamp screw can compromise insert seating, lead to chatter, or cause premature insert failure, making correct replacement hardware essential for maintaining cutting performance and dimensional accuracy on the machine.

This screw is used in metalworking and machining environments where indexable insert tooling is employed. Typical installers are machinists, tool crib technicians, and CNC setup personnel working in production or job-shop settings. The part is suited for maintenance stock in facilities that run high volumes of indexable tooling and require ready access to replacement hardware to minimize downtime during insert changes.

Designed as an OEM-style clamping screw for Kennametal indexable insert toolholders. Consult the specific toolholder documentation or Kennametal product catalog to confirm thread size and head-drive compatibility before ordering.

Installation Notes

Installation is performed by machinists or tool setup personnel. Always power down and lock out the machine spindle before servicing indexable tooling. Use the correct Torx or hex key drive specified by the toolholder manufacturer to avoid stripping the screw head. Do not reuse visibly damaged or deformed clamp screws, as compromised fasteners can allow insert movement during cutting.
