Kennametal 4158728 Replaceable Drill Tip KCP15 Kentip

Product Description

The KENNAMETAL 4158728 is a replaceable drill tip designed for use with KenTIP modular drilling systems. It features a 0.3125 inch (7.94 mm) cutting diameter and is manufactured from solid carbide with a KCP15 grade substrate. The AlTiN coating is applied via a PVD process, providing heat resistance and extended tool life in demanding cutting applications. The HP insert geometry and 140-degree included angle are engineered for high-performance drilling in a range of workpiece materials. This tip is installed and replaced by machinists and tool-crib technicians as part of routine tooling maintenance on CNC and manual drilling equipment.

The 4158728 is suited for production drilling environments where modular tooling systems reduce downtime by allowing tip replacement without changing the full drill body. It fits Seat Size F KenTIP holders and is appropriate for use in job shop, aerospace, automotive, and general metalworking applications. The KTIP03125 style designation identifies the correct holder seat for this tip diameter. Sold individually, it is a direct replacement tip within the KenTIP platform.

Installation Notes

Installation is performed by a machinist or tooling technician following the machine tool manufacturer and tooling system guidelines. The machine spindle must be fully stopped and locked out before removing or seating a replaceable drill tip. Use the correct torque wrench or tip-seating tool specified for the KenTIP holder to avoid damaging the seat or tip shank. Inspect the holder seat for wear, chips, or debris before installing a new tip.
