Kennametal 2499730 Carbide Replaceable Tip Drill 13.50mm

Product Description

The KENNAMETAL 2499730 is a solid carbide replaceable tip drill from the KSEM series, designed for precision drilling in steel and cast iron applications. The insert tip carries the ISO designation KSEM1350HPGM and is manufactured in grade KC7315 using fine grain carbide with a PVD-applied TiAlN coating. The 140-degree drill point angle and helical fluting support clean entry and efficient chip evacuation. At 13.50mm cutting diameter, this drill is suited for demanding metal-cutting environments where tool life and hole quality are critical. Licensed machinists and CNC operators working in production or job-shop environments are the primary users.

This replaceable tip drill is built for ferrous material drilling, including steel and cast iron workpieces. The HPG insert geometry and regular spiral flute design handle common production scenarios such as straight drilling, inclined exit conditions, and stacked plate drilling. The insert seat size is C and the holding method is mechanical clamp. Coolant-through capability supports both flood coolant and MQL (Minimum Quantity Lubrication) delivery, making this drill adaptable to a range of machine tool setups and shop coolant strategies.

Key Features

• Solid carbide tip in grade KC7315 fine grain material for extended wear resistance in steel and cast iron
• TiAlN coating applied via PVD process for thermal protection and surface hardness
• 140-degree drill point angle with standard point type for accurate entry and reduced thrust
• Coolant-through design compatible with flood coolant and MQL systems
• HPG insert geometry with 2-flute, 2-margin configuration for hole quality and stability
• Suitable for inclined exit and stacked plate drilling applications

Compatibility

Designed as an OEM-style replaceable tip for KSEM series drill bodies accepting insert seat size C. Primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and the tool holder secured before seating or removing the replaceable tip. Use the appropriate torque wrench and clamp hardware specified for the KSEM insert seat size C to avoid tip movement or seat damage. Verify coolant-through passages are clear before operation to maintain proper chip evacuation and tool temperature control.
