Kennametal 1191143 Hts Dft Outer Drill Cartridge

Product Description

The KENNAMETAL 1191143 is a Series HTS DFT outer drill cartridge designed for deep-hole and indexable drilling applications. This cartridge accepts three DFT 05T308 inserts and mounts in the outer cartridge position of compatible HTS DFT drill bodies. It is a precision-machined tooling component used by machinists and tooling specialists in production metal-cutting environments where indexable insert drills are required for consistent bore quality and repeatable performance. The cartridge acts as the interface between the drill body and the cutting inserts, controlling insert position and depth of cut at the outer cutting diameter.

This cartridge is suited for use in CNC turning centers, machining centers, and similar machine tools where HTS DFT series indexable drills are in operation. It is typically installed during tooling setup or when replacing worn or damaged outer cartridges in an existing drill assembly. Machinists and tooling engineers working in automotive, aerospace, and general precision machining operations are the primary users of this component.

Key Features

• Outer cartridge position for HTS DFT series drill bodies
• Accepts three DFT 05T308 finishing inserts
• Indexable cartridge design allows insert replacement without scrapping the full drill body
• Precision-ground seating surfaces support repeatable insert location and bore accuracy
• Lightweight construction at 0.3946 pounds for minimal spindle load contribution

Compatibility

Designed for use with KENNAMETAL Series HTS DFT indexable drill bodies in the outer cartridge position, using DFT 05T308 inserts. Confirm drill body series and cartridge location before ordering.

Installation Notes

Installation and cartridge exchange should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine in a locked-out, de-energized state. Use appropriate torque tools and follow the drill body manufacturer's assembly procedures for cartridge seating and insert clamping. Inspect the cartridge pocket in the drill body for wear or damage before installing a replacement cartridge. Do not force the cartridge into position; proper seating is required to maintain insert location accuracy.
