Kennametal 5118450 Indexable Drill Insert Dfchp KCU25

Product Description

The KENNAMETAL 5118450 is a solid carbide indexable drill insert designed for high-performance drilling applications in metal-cutting operations. Built to the DFCHP style with a KCU25 manufacturer grade, it features a physical vapor deposition (PVD) AlTiN coating that improves wear resistance and thermal stability during aggressive cutting cycles. The insert has a 90-degree included angle, a corner radius of 0.032 inches (0.81 mm), and a thickness of 0.187 inches. The HP chipbreaker geometry promotes reliable chip evacuation in a range of ferrous and non-ferrous workpiece materials. This insert is installed by machinists and tool-and-die professionals in CNC drilling and machining centers.

The 5118450 is suited for indexable drill toolholders requiring a DFC-style insert with neutral hand orientation. It is applicable in precision drilling operations on steel, stainless steel, and similar materials in both production and job-shop environments. The 0.81 mm corner radius and 8-degree relief angle make it appropriate for applications demanding tight tolerances and controlled chip formation. The insert size designation is 070416, with a length of 0.7087 inches (18.00 mm) and a width of 0.571 inches.

Key Features

• KCU25 carbide grade with PVD AlTiN coating for enhanced wear resistance and heat management
• DFCHP insert style with HP chipbreaker for reliable chip control in drilling operations
• 90-degree included angle for accurate entry geometry in CNC drill applications
• Corner radius of 0.032 inches (0.81 mm) for controlled edge strength at the cutting tip
• 8-degree relief angle reduces friction and improves clearance behind the cutting edge
• Neutral hand orientation allows flexible positioning in compatible toolholders

Compatibility

Designed as an OEM-style replacement insert for indexable drill toolholders requiring a DFC-style, size 070416 carbide insert with neutral hand orientation.

Installation Notes

This insert is installed by qualified machinists or tool-room technicians. Before indexing or replacing inserts, ensure the machine spindle is fully stopped and locked out per facility lockout/tagout procedures. Use the appropriate torx or hex key driver to seat the insert securely in the toolholder pocket without over-torquing the clamping screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
