Kennametal 1191142 Hts Dft Inner Drill Cartridge

Product Description

The KENNAMETAL 1191142 is an inner drill cartridge from the HTS DFT series, designed for use in indexable drill bodies that require a 3-insert inner cartridge configuration. This cartridge accepts DFT 05T308 inserts and is positioned at the inner cutting zone of the drill body, handling the central portion of the bore during deep-hole or high-feed drilling operations. Weighing 0.3748 pounds, it is a precision replacement component used by machinists and tooling specialists in CNC and production drilling applications. Proper cartridge selection and insert seating directly affect hole quality, tool life, and cycle time.

This cartridge is suited for production drilling environments where indexable insert tooling is used to achieve consistent bore dimensions at high material removal rates. The inner cartridge location means it engages the center of the cutting zone, making accurate seating and secure clamping critical. It is typically installed in machining centers, horizontal boring mills, and lathe turrets running HTS DFT series drill bodies. Tooling engineers and CNC setup technicians are the primary users during scheduled insert changes or cartridge replacement due to wear or damage.

Key Features

• Accepts 3 DFT 05T308 inserts per cartridge
• Part of the HTS DFT series for compatibility within that tooling platform
• Lightweight construction at 0.3748 pounds for easy handling during tool changes
• OEM replacement cartridge maintaining original drill body geometry and performance

Compatibility

Designed for use with HTS DFT series indexable drill bodies requiring a 3-insert inner cartridge. Uses DFT 05T308 inserts. Consult the HTS DFT series tooling documentation to confirm drill body size and cartridge position before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable drill body systems. Power down and lock out the machine spindle before removing or installing cartridges. Use the appropriate torque wrench and insert clamping screws specified for the HTS DFT drill body to avoid cartridge damage or improper seating. Inspect the cartridge pocket in the drill body for wear or debris before installing the replacement cartridge.
