Kennametal 2050113 L-key TP25 Torx Plus Boring Bar

Product Description

The KENNAMETAL 2050113 is a TP25 Torx Plus L-Key designed for tightening and loosening clamp screws on indexable cutting tools. This hex-style wrench delivers the precise torque engagement required for secure insert clamping on boring bar and grooving toolholders. Weighing just 0.05 pounds, it is a compact, single-piece hand tool sized specifically for the TP25 Torx Plus drive standard. Machining professionals and toolroom technicians use this L-Key during insert changes and setup operations where proper screw engagement prevents insert movement and tool failure under cutting loads.

This L-Key is used in metal cutting and machining environments where indexable tooling requires routine insert rotation or replacement. It is compatible with clamp screw MS2111 and supports insert styles N.3L, N.3R, and N.4L. Typical applications include boring bar and grooving operations on CNC lathes and turning centers. The TP25 Torx Plus drive reduces the risk of cam-out during torque application, making it well suited for production environments where inserts are changed frequently.
