Kennametal 1963856 Insert Holding Screw T10 Torx

Product Description

The KENNAMETAL 1963856 is a T10 Torx insert holding screw designed for indexable boring bar toolholders in the S Series line. This hardware component secures cutting inserts in place during metal removal operations, maintaining precise positioning under cutting loads. It is compatible with SSBI-style toolholder bodies. Machinists and toolroom technicians install this screw when replacing worn or damaged insert clamping hardware on indexable boring bar assemblies. The T10 Torx drive provides reliable torque transfer with reduced cam-out risk compared to hex drives, making it a preferred fastener type in precision toolholding applications.

This screw is used in CNC turning centers, boring mills, and manual lathes wherever SSBI-style S Series boring bars are in service. It is a standard maintenance and replacement item for shops running indexable tooling. When inserts are rotated or replaced, the clamping screw is inspected and replaced as needed to maintain secure insert seating and dimensional accuracy in the bore. The package quantity is 1 piece, and the minimum order quantity is 1.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or replacement.

Use a calibrated T10 Torx driver and follow the toolholder manufacturer torque specifications found in the toolholder documentation. Inspect the screw threads and seating surface for wear or damage before reinstalling an insert.
