Kennametal 6178233 Indexable Drill Insert Dftgd KC7140

Product Description

The KENNAMETAL 6178233 is a trigon-style indexable drill insert designed for use in indexable drill tooling systems. This insert features a KC7140 carbide grade with a PVD-applied TiN coating, delivering wear resistance and thermal stability during drilling operations. The insert carries a neutral hand designation, an 84-degree included angle, and a 1/32 inch corner radius. Size designation is 05T308. Machinists and tooling specialists install this insert as a replaceable cutting element in compatible indexable drill bodies, making it a cost-effective alternative to replacing entire drill assemblies.

This insert is suited for drilling applications in metalworking environments where consistent hole quality and insert life are required. The GD chipbreaker geometry promotes controlled chip evacuation during through-hole and blind-hole drilling operations. The neutral hand orientation allows fitment in standard indexable drill bodies without a handed pocket restriction. Typical applications include production machining on CNC machining centers and drill presses in general metalworking, mold and die, and contract machining shops.

Key Features

• KC7140 carbide grade with PVD TiN coating for wear and heat resistance
• Trigon (84-degree included angle) insert shape with DFT insert style
• GD chipbreaker for controlled chip flow during drilling
• 1/32 inch corner radius for edge strength and finish consistency
• Neutral hand orientation for broad toolholder compatibility
• Insert size 05T308 with 3.4 mm mounting hole diameter

Compatibility

Designed as an OEM-style replacement insert for KENNAMETAL indexable drill systems accepting DFT-style trigon inserts in the 05T308 size class.

Installation Notes

Indexable drill inserts are installed and replaced by machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the manufacturer-specified torx or hex key to seat the insert clamp screw; do not overtighten by feel alone. Inspect the drill body pocket for wear or damage before seating a new insert to ensure proper support and runout.
