Kennametal 1191136 Hts Dft Inner Drill Cartridge

Product Description

The KENNAMETAL 1191136 is a Series HTS DFT inner drill cartridge designed for use in indexable drill tooling systems. It holds 2 DFT 05T308 finishing inserts in the inner cartridge position, providing accurate cutting geometry at the center of the bore during deep-hole or high-throughput drilling operations. This cartridge is a precision-machined replacement component that seats directly into compatible HTS DFT drill bodies. Tooling engineers, machining centers, and production shops running indexable drilling programs rely on this type of cartridge to maintain consistent bore quality and reduce changeover time compared to brazed tooling.

This cartridge is intended for use in Series HTS DFT indexable drill bodies that accept inner-position cartridges. It is suited for metal-cutting applications in ferrous and non-ferrous materials where the inner cutting zone requires a dedicated insert seat arrangement. Typical install environments include CNC turning centers, machining centers, and transfer line machines running production drilling cycles. It functions as part of a two-cartridge system, with this unit occupying the inner location closest to the drill centerline.

Key Features

• Inner cartridge position for Series HTS DFT indexable drill bodies
• Accepts 2 DFT 05T308 finishing inserts
• Precision-machined seating for repeatable insert location and bore accuracy
• Drop-in replacement design reduces downtime during insert or cartridge changes
• Lightweight construction at 0.19 pounds for minimal mass addition to the drill body

Compatibility

Designed for use with Series HTS DFT indexable drill bodies requiring an inner cartridge position. Uses DFT 05T308 inserts. Consult the HTS DFT tooling system documentation to confirm compatibility with your specific drill body diameter and body generation before ordering.

Installation Notes

Cartridge installation and insert indexing should be performed by a qualified machinist or tooling technician with the spindle fully locked out and the machine in a de-energized state. Use only the manufacturer-specified torque tools and insert clamping hardware when seating the cartridge and securing inserts. Inspect the cartridge pocket in the drill body for chips, debris, or damage before installation. Do not force the cartridge into the pocket; proper seating should require only light hand pressure followed by correct fastener engagement.
