Kennametal 1260086 Cap Screw T6 Torx 1-72 Thread

Product Description

The KENNAMETAL 1260086 is a cap screw designed to secure indexable inserts in boring bar toolholders. This T6 Torx-drive fastener uses a 1-72 thread and measures 0.088 inches in overall length. It belongs to the C Series hardware line and is intended for use with compatible KENNAMETAL insert clamp boring bars. Licensed machinists and toolroom technicians install this type of hardware during insert changes or toolholder maintenance. The small form factor and precise thread specification make it critical to proper insert seating and cutting performance. Sold individually, with a minimum order quantity of 20 pieces.

This cap screw is used in CNC and manual boring operations where indexable insert toolholders are employed. It is compatible with CSBI-series boring bar toolholders and accepts CDCD, CDCG, and CDCT series inserts. The T6 Torx drive requires the KENNAMETAL C KEY driver for correct installation. Typical applications include internal diameter boring on lathes and machining centers in both production and job shop environments. The 1-72 fine thread pitch provides secure clamping force suited to the tight tolerances required in indexable tooling assemblies.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during scheduled insert indexing or replacement. Shut down the machine spindle and confirm zero motion before accessing the toolholder. Use only the designated KENNAMETAL C KEY driver to engage the T6 Torx socket — substitute drivers risk stripping the drive recess on this small-diameter fastener. Inspect the thread bore in the toolholder for chips or debris before reinstalling the screw.
