Kennametal 6388654 Drill Tip 9.50mm 143deg KCP15A Altin

Product Description

The KENNAMETAL 6388654 is a replaceable drill tip designed for use with KTFS-series indexable drill bodies. It features a 0.374-inch (9.50 mm) cutting diameter, a 143-degree included drill point angle, and is manufactured from solid carbide in grade KCP15A. The AlTiN coating is applied via a PVD process, providing elevated heat resistance and wear performance in demanding cutting applications. This tip installs into an I-seat size drill body and is intended for use by machinists and tooling professionals in production turning and drilling environments.

This replaceable tip is suited for metalworking operations in both job shop and production settings. The HPG insert geometry and KCP15A carbide grade make it applicable to a range of ferrous materials where consistent hole quality and tool life are priorities. Coolant-through delivery is not supported by this tip configuration. Seat size I limits fitment to compatible KTFS-series drill bodies with the corresponding seat designation.
