Kennametal 4158986 Replaceable Drill Tip 15mm KCP15 Altin

Product Description

The KENNAMETAL 4158986 is a replaceable drill tip designed for use in the KenTIP modular drilling system. It features a 0.5906-inch (15.00 mm) cutting diameter and is manufactured from solid carbide with a KCP15 grade designation. The AlTiN coating is applied via a PVD process, providing thermal resistance and wear protection in demanding metal-cutting applications. The HP insert geometry supports high-performance drilling, and the included angle measures 140 degrees. This tip is intended for installation by machinists and toolroom technicians working with modular indexable drill bodies.

The 4158986 replaceable drill tip fits within the KenTIP series modular drilling platform. It is suited for production machining environments including CNC turning centers and machining centers where consistent hole quality and rapid tip replacement are priorities. The seat size T designation matches it to compatible KENNAMETAL KenTIP drill bodies of the appropriate shank size. Applications span general-purpose metal cutting in steel, stainless, and cast materials where PVD-coated carbide tooling is specified.

Key Features

• Solid carbide construction with KCP15 grade for wear resistance in metal cutting
• AlTiN coating applied via PVD process for thermal and oxidation resistance
• HP insert geometry engineered for high-performance drilling operations
• 140-degree included angle for self-centering entry and reduced thrust
• Insert seat size T for precise, repeatable seating in compatible drill bodies
• Part of the KenTIP series modular system enabling fast tip exchanges without removing the drill body

Compatibility

Designed as an OEM-style replaceable tip for KENNAMETAL KenTIP series modular drill bodies accepting seat size T inserts with a 15.00 mm cutting diameter. Refer to KENNAMETAL tooling catalogs to confirm compatible drill body part numbers before ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the drill body manufacturer's torque and assembly procedures. Ensure the drill body spindle and machine are fully powered down and locked out before replacing the tip. Inspect the insert seat for chips, debris, or wear before seating the new tip, as contamination affects runout and hole quality. Follow all applicable shop safety and machine guarding protocols during tool changes.
