Kennametal 1130295 Central Lock Screw 1/4-18 Thread

Product Description

The KENNAMETAL 1130295 is a central lock screw designed to secure indexable inserts in drilling toolholders. This hardware component threads into the insert pocket and clamps the cutting insert firmly in place during machining operations, maintaining precise positioning under cutting loads. It carries a 1/4-18 thread specification and is built for use in indexable drilling applications where reliable insert retention is critical. Installation is performed by tooling technicians or machinists during insert changeover on CNC or manual drilling setups.

This central lock screw is used in indexable drilling toolholders that accept compatible insert-locking hardware. It is a direct-replacement maintenance consumable, typically stocked alongside indexable inserts and replaced as part of routine toolholder servicing when screw threads show wear or damage. Suitable for production machining environments in metal removal applications.

Compatibility

Designed for use with indexable drilling toolholders requiring a 1/4-18 central lock screw for insert retention. Consult the toolholder manufacturer documentation to confirm thread specification match before ordering.

Installation Notes

Installation is performed by machinists or tooling technicians during scheduled insert changeover. Always ensure the spindle or machine is fully powered down and locked out before servicing the toolholder. Use the appropriate Torx or hex key driver specified by the toolholder manufacturer when seating the lock screw. Do not overtighten, as this can damage the screw threads or the insert pocket seating surface.
