Kennametal 1099676 L-key T30 Torx Drive Indexable

Product Description

The KENNAMETAL 1099676 is a T30 Torx L-Key designed for tightening and loosening clamp screws on indexable cutting tool assemblies. This wrench-style hex key provides the correct drive interface for secure torque application to Torx-head clamp screws, including MS1595-compatible fasteners commonly found on indexable insert toolholders. Weighing just 0.05 pounds, it is a compact, dedicated tool kept in a machinist or toolroom service kit. Licensed tradespeople and CNC toolroom technicians use it during insert indexing, insert replacement, and toolholder setup operations where correct fastener engagement is critical to cutting performance and insert retention.

This L-Key is intended for use in metalworking and machining environments where indexable insert toolholders require periodic insert changes or clamp screw servicing. It is suited to both production floor use and toolroom maintenance settings. The T30 Torx drive size matches a specific range of clamp screws used across indexable milling, turning, and boring toolholder platforms that rely on Torx-style fasteners.

Compatibility

Compatible with Torx clamp screws meeting the MS1595 specification. Designed for use with indexable insert toolholders that require a T30 Torx drive fastener for clamp screw installation and removal.

Installation Notes

This L-Key is used by machinists and toolroom technicians during indexable insert changes. Before servicing any toolholder, ensure the machine spindle is powered down and locked out per applicable lockout/tagout procedures. Apply steady, controlled torque through the L-Key to avoid cam-out or fastener damage. Refer to the toolholder manufacturer's recommended clamp screw torque specification for proper fastener seating.
