Kennametal 6025892 Indexable Drill Insert Dftds KCU40

Product Description

The KENNAMETAL 6025892 is a solid carbide indexable drill insert designed for use in indexable insert drills in metalcutting operations. It carries the KCU40 manufacturer grade and features a Physical Vapor Deposition (PVD)-applied TiAlN coating, which provides thermal resistance and wear protection during high-speed drilling. The insert has an 84-degree trigon shape with a 5.5 mm inscribed circle and a 0.8 mm corner radius. The DS chipbreaker geometry promotes controlled chip formation and evacuation in through-hole and blind-hole drilling applications. This insert is installed by machinists and CNC operators in production and job-shop environments.

This insert is suited for drilling operations in ferrous and non-ferrous materials where a neutral-hand, trigon-style carbide insert is specified. The DFT insert style makes it compatible with indexable drill systems that accept that seat geometry. The 5.5 mm inscribed circle and 0.8 mm corner radius define a compact cutting profile appropriate for smaller-diameter hole applications. It is used in horizontal machining centers, vertical mills, and turning centers equipped with live tooling.

Key Features

• KCU40 solid carbide grade with PVD TiAlN coating for wear and heat resistance
• 84-degree trigon shape with DS chipbreaker for controlled chip flow
• 5.5 mm inscribed circle and 0.8 mm corner radius for precise cutting geometry
• Neutral-hand insert orientation for flexible tool body seating
• Insert size designation 090508 for direct cross-reference during ordering

Compatibility

Designed as an OEM-style replacement or direct-fit insert for indexable drill tool bodies that accept the DFT insert style with a 5.5 mm inscribed circle seating geometry.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and the tool body secured in a vise or fixture before seating or removing the insert. Use the appropriate Torx or hex key to torque the insert clamp screw to the tool body manufacturer specification. Inspect the insert pocket for debris or wear before seating a new insert to ensure proper contact and runout.
