Kennametal 2499744 Replaceable Drill Tip 15mm KC7315

Product Description

The KENNAMETAL 2499744 is a replaceable drill tip designed for use with KSEM modular drilling systems. It features a 15.00 mm (0.5906 inches) cutting diameter, a 140-degree included point angle, and a solid carbide construction with a PVD-applied TiAlN coating. The HPG insert geometry and fine grain carbide grade KC7315 are engineered for productive drilling in steel and cast iron applications. Coolant-through capability supports both flood coolant and minimum quantity lubrication (MQL) delivery. The tip mounts in an Insert Seat Size A holder using a clamp-style insert holding method. Licensed machinists and CNC operators working in production or maintenance machining environments are the primary installers.

This drill tip is suited for demanding drilling operations including standard through-drilling, inclined exit drilling, and stacked plate drilling. The 2-flute, 2-margin helical flute design with regular spiral promotes chip evacuation and hole quality in ferrous workpiece materials. Primary workpiece material codes P (steel) and K (cast iron) define its core application range. The functional length and flute length are each 7.00 mm (0.2953 inches), making this a compact tip suited for precise modular drill assemblies.

Key Features

• 15.00 mm cutting diameter with 140-degree standard point angle for reliable entry and exit
• Solid carbide construction, fine grain grade KC7315 for wear resistance in ferrous materials
• PVD TiAlN coating improves heat resistance and tool life in steel and cast iron
• HPG insert geometry supports inclined exit, stacked plate, and standard through-drilling
• Coolant-through design compatible with flood coolant and MQL delivery methods
• 2-flute, 2-margin helical flute configuration promotes chip evacuation and bore quality

Compatibility

Designed for use with KSEM modular drill bodies that accept Insert Seat Size A replaceable tips. Compatible with applications involving steel (ISO material code P) and cast iron (ISO material code K) workpieces.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Ensure the KSEM drill body is removed from the spindle and the machine is locked out before seating or removing the tip. Use the appropriate KSEM torx or clamping key to secure the insert to the specified holding method. Verify coolant-through passages are clear before reassembling the tool into the spindle.
