Kennametal 5067312 Indexable Drill Insert KCU25 Altin

Product Description

The KENNAMETAL 5067312 is a solid carbide indexable drill insert designed for precision drilling operations in metal-cutting applications. Manufactured in insert style DFR with a GD chipbreaker geometry, this insert carries the KCU25 grade designation and is finished with an AlTiN coating applied via PVD process. It features a 6 mm (0.2362 inch) inscribed circle, a thickness of 0.1134 inches, and a corner radius of 0.40 mm (1/64 inch). The neutral hand orientation allows straightforward indexing. Machining professionals, toolroom technicians, and production machinists install this insert into compatible indexable drill bodies as a replacement cutting element.

This insert is suited for indexable drilling applications where carbide grades with wear-resistant AlTiN coatings are specified. The KCU25 grade with PVD AlTiN coating performs in a range of ferrous and non-ferrous workpiece materials at moderate to high cutting speeds. The GD chipbreaker geometry assists with chip control in through-hole and blind-hole drilling operations. Insert size designation 030204 identifies the geometry class. This insert is sold individually, though a minimum order quantity of 10 units applies.

Key Features

• KCU25 solid carbide grade with PVD-applied AlTiN coating for elevated wear resistance

Compatibility

Designed as an OEM-style replacement indexable drill insert for compatible KENNAMETAL indexable drill bodies that accept DFR-style inserts with a 6 mm inscribed circle and 030204 insert size designation. Verify seat geometry and clamping screw specifications against the drill body documentation before ordering.

Installation Notes

Installation and replacement of indexable drill inserts is performed by machinists or toolroom technicians following the drill body manufacturer's torque specifications for the clamping screw - consult the drill body documentation for the correct value, as it is not specified here. Ensure the machine spindle is fully stopped and the tool is secured or removed from the holder before handling inserts. Inspect the insert pocket seat and clamping screw for wear or damage before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edges prior to use.
