Kennametal 1312498 Lock Screw Indexable Ksem Drilling

Product Description

The KENNAMETAL 1312498 is a lock screw designed to secure indexable inserts in compatible toolholders used in drilling applications. This small but critical fastener holds the cutting insert firmly in place during machining operations, preventing movement or ejection under cutting forces. It is compatible with the KSEM toolholder style and is used with the TPGX 1603ZPR insert. Installation requires the 170.276 key or driver. At 0.01 pounds, this is a lightweight precision hardware component typically sourced as a replacement or spare by machining shops and CNC tooling professionals.

This lock screw is intended for use in indexable drilling toolholders following the KSEM style. It is a direct hardware component for insert retention, making it a standard service item in production machining environments where insert changes are frequent. The screw is sold individually and is suited for both shop floor replacement and toolcrib inventory replenishment. It fits within KENNAMETAL's line of indexable drilling hardware and is typically installed by machinists or tooling technicians during insert indexing or toolholder maintenance.

Installation Notes

Lock screws for indexable toolholders are installed and removed by machinists or tooling technicians during routine insert changes. Always ensure the machine spindle is fully stopped and locked out before accessing the toolholder. Use only the specified 170.276 key or driver to avoid stripping the screw head. Do not overtighten, as lock screws in indexable systems are torque-sensitive components.
