Kennametal 2045294 Indexable Drill Insert Dfthp KC7140

Product Description

The KENNAMETAL 2045294 is a solid carbide indexable drill insert designed for high-performance drilling applications in metalcutting operations. It features an 84-degree trigon shape with a DFT insert style and an HP chipbreaker geometry, which promotes efficient chip control during interrupted and continuous cuts. The insert is PVD-coated with TiN and TiCN layers through a grade KC7140 process, offering wear resistance and thermal stability suited for C5 and C6 material grades. With an inscribed circle of 0.2362 inches (6 mm) and a corner radius of 0.0157 inches (0.40 mm), it delivers consistent edge geometry for indexable drill tooling systems. Licensed machinists and CNC operators install this insert in compatible drill bodies.

This insert is intended for use in indexable drilling operations on machining centers, CNC lathes, and drill press setups where replaceable carbide inserts are required. It is well suited for productive metal removal in ferrous and non-ferrous materials where PVD-coated carbide grades such as KC7140 are specified. The HP chipbreaker designation targets applications where controlled chip evacuation is critical to hole quality and tool life. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. The machine spindle must be fully powered down and locked out before changing inserts. Use the correct torx or hex key as specified by the drill body manufacturer to seat the insert at the proper clamp torque. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper contact and runout.
