Kennametal 1806435 Indexable Drill Insert Dfrgd KC7140

Product Description

The KENNAMETAL 1806435 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. Carrying the DFRGD insert style with a KC7140 manufacturer grade, this insert features a PVD-applied TiN and TiCN multilayer coating that improves wear resistance and extends cutting life in demanding machining operations. The inscribed circle measures 0.236 inches, thickness is 0.1134 inches, and the corner radius is 0.40 mm (0.0157 inches). It carries material grade designations C5 and C6, making it appropriate for a range of ferrous and non-ferrous cutting applications. Machinists and tooling technicians working in production or job-shop environments install and index these inserts as part of regular tooling maintenance.

This insert is suited for use in indexable drill bodies that accept DFRGD-style inserts with an insert size designation of 030204. It is applicable in CNC machining centers, turning centers with live tooling, and dedicated drill press setups where precision hole-making is required. The GD chipbreaker geometry supports chip control during drilling operations in materials falling within the C5 and C6 material grade range. The insert ships individually with a minimum order quantity of 5 units per order.

Key Features

• Solid carbide construction with PVD-applied TiN and TiCN multilayer coating for extended wear life
• DFRGD insert style with GD chipbreaker geometry for controlled chip evacuation during drilling
• KC7140 manufacturer grade rated for C5 and C6 material groups
• Inscribed circle of 0.236 inches and corner radius of 0.40 mm for consistent dimensional accuracy
• Insert size 030204 for compatibility with matching indexable drill body systems
• Mounting hole diameter of 0.0984 inches for secure clamping in the drill body pocket

Compatibility

Designed for use in indexable drill bodies that accept DFRGD-style inserts with insert size 030204. Verify the drill body manufacturer specifications to confirm pocket geometry and clamping screw compatibility before ordering.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the correct Torx or hex key as specified by the drill body manufacturer to seat the clamping screw - do not overtighten or use impact tools on the insert screw. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
