Kennametal 6178232 Indexable Drill Insert Dftgd KC7140

Product Description

The KENNAMETAL 6178232 is a solid carbide indexable drill insert designed for use in indexable drilling applications where consistent cutting performance and tool life are critical. Manufactured to the DFT insert style with a GD chipbreaker, this insert features a Trigon (84-degree included angle) geometry and a TiN coating applied via PVD process. The 6 mm inscribed circle and 1/64-inch corner radius define its cutting profile. Insert size designation is 030304. Licensed HVAC, plumbing, and electrical work is outside its scope — this insert is specified and installed by machinists and tooling technicians working in metal-cutting operations.

This insert is suited for indexable drill bodies that accept DFT-style inserts with a 6 mm inscribed circle. It is appropriate for applications in ferrous and non-ferrous metal drilling where TiN-coated carbide tooling is specified. The neutral hand orientation makes it compatible with both right-hand and left-hand drill body configurations. It is commonly used in production machining environments, job shops, and maintenance repair operations where repeatable hole quality is required.

Key Features

• Solid carbide substrate with PVD-applied TiN coating for extended wear resistance
• GD chipbreaker geometry promotes controlled chip evacuation during drilling
• 84-degree included angle Trigon shape for positive cutting action
• 6 mm inscribed circle with 1/64-inch corner radius for precise fitment
• Neutral hand insert — compatible with right-hand and left-hand drill bodies
• Insert size 030304 for straightforward cross-referencing with drill body specifications

Compatibility

Designed for use in indexable drill bodies that accept DFT insert style with a 6 mm inscribed circle and 030304 insert size designation. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing any insert. Use the correct torque wrench and manufacturer-specified fastener when securing the insert in the drill body pocket — do not overtighten by feel alone. Inspect the pocket seat and clamping screw for wear or debris before installing a new insert to ensure proper seating and runout.
