Kennametal 5066019 Indexable Drill Insert Dftmd KCU40

Product Description

The KENNAMETAL 5066019 is a solid carbide indexable drill insert designed for use in indexable drilling operations on CNC machining centers, lathes, and drill presses. It carries the DFTMD designation, combining a DFT insert style with an MD chipbreaker geometry, and is manufactured in the KCU40 grade. The insert is PVD-coated with a TiN and TiAlN multilayer finish, providing wear resistance and thermal stability in demanding cutting conditions. With an inscribed circle of 10 mm (0.3937 inches), a thickness of 0.1476 inches, and a corner radius of 1/32 inch (0.0313 inches), this insert suits precision drilling applications where consistent chip control and hole quality are required. Installation is performed by qualified machinists or toolroom technicians.

This insert is suited for indexable drilling tool bodies that accept DFT-style, 84-degree trigon inserts with an 06T308 insert size. Typical applications include drilling operations in steel, stainless steel, and other ferrous materials in both production and job-shop environments. The neutral hand orientation makes it compatible with standard right-hand drill bodies running conventional spindle rotation. The MD chipbreaker geometry is engineered for controlled chip formation in medium-duty drilling operations.

Key Features

• PVD-applied TiN and TiAlN multilayer coating for enhanced wear resistance and heat dissipation
• MD chipbreaker geometry for controlled chip evacuation in medium-duty drilling
• KCU40 carbide grade balances toughness and wear resistance for ferrous materials
• Neutral hand orientation compatible with standard right-hand drill bodies
• 84-degree trigon shape with 0.0313-inch corner radius for stable cutting geometry
• Insert size 06T308 for precise fitment in compatible DFT-style tool bodies

Compatibility

Designed as an OEM-style replacement or replenishment insert for indexable drill bodies accepting DFT-style trigon inserts in size 06T308 with an 84-degree included angle.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate Torx or hex key to the tool body manufacturer torque specification when securing the insert clamp screw. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper seating and runout.
