Kennametal 6178234 Indexable Drill Insert Dftgd KC7140

Product Description

The KENNAMETAL 6178234 is a solid carbide indexable drill insert designed for use in indexable drilling applications where consistent hole quality and tool life are critical. Manufactured to an 84-degree trigon shape with a GD chipbreaker, this insert carries a KC7140 grade with a PVD-applied TiN coating that supports cutting performance in a range of workpiece materials. The inscribed circle measures 10 mm, the corner radius is 1/32 inches, and the insert size is 06T308. Installation requires no grinding or edge prep. Machinists and tooling specialists working in metal cutting environments select this insert for its neutral hand orientation and repeatable indexing geometry.

This insert is suited for use in indexable drill bodies that accept DFT-style inserts with a 10 mm inscribed circle and an 06T308 insert seat. Typical applications include through-hole and blind-hole drilling operations in ferrous and non-ferrous metals on CNC machining centers and lathes. The 84-degree included angle and GD chipbreaker geometry support chip control during interrupted or continuous cutting cycles.

Key Features

• Solid carbide substrate with PVD TiN coating for wear resistance
• KC7140 manufacturer grade optimized for indexable drilling
• 84-degree trigon shape with GD chipbreaker for controlled chip evacuation
• 10 mm inscribed circle, 06T308 insert size for precise seat fit
• Neutral hand orientation for flexible application use
• 1/32-inch corner radius reduces edge stress at entry and exit

Compatibility

Designed for use in indexable drill bodies that accept DFT-style inserts with an 06T308 seat size and 10 mm inscribed circle. Verify drill body manufacturer specifications before installation to confirm insert seat geometry and clamping screw compatibility.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling specialist with the spindle fully de-energized and the machine in a locked-out state. Use the correct torx or hex key specified by the drill body manufacturer to achieve proper clamping torque without over-tightening the insert screw. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Never use a damaged or improperly seated insert, as this can result in insert ejection or premature tool failure.
