Kennametal 2499782 Carbide Replaceable Tip Drill 22.5mm

Product Description

The KENNAMETAL 2499782 is a carbide replaceable tip drill from the KSEM series, designed for high-productivity hole-making in steel and cast iron. The solid carbide tip carries the KC7315 manufacturer grade with a PVD-applied TiAlN coating, delivering thermal and wear resistance in demanding cutting conditions. The HPG insert geometry and 140-degree drill point angle support chip control and accurate entry across a range of workpiece setups. With a cutting diameter of 22.5 millimeters and through-coolant capability, this drill is suited for production machining environments where tool life and cycle time matter. Licensed machinists and CNC operators are the primary installers and users of this tool.

The KENNAMETAL 2499782 is applied in drilling operations on steel and cast iron workpieces, including applications on inclined exit surfaces and stacked plate assemblies. The 2-flute, 2-margin helical flute design handles standard through-coolant delivery as well as MQL (Minimum Quantity Lubricant) setups. It fits toolholders sized for KSEM insert seat size 4, making it appropriate for machining centers and CNC drill presses running KSEM-series bodies in job shop and production environments alike.

Key Features

• Solid carbide KC7315-grade tip with PVD TiAlN coating for extended tool life in steel and cast iron
• 22.5 mm cutting diameter with 140-degree included drill point angle for accurate hole entry
• HPG insert geometry supports chip control on inclined exits and stacked plates
• Through-coolant and MQL compatible for flexible coolant strategy
• 2-flute helical design with regular spiral for balanced cutting forces
• Replaceable tip design reduces cost per hole versus solid carbide drills

Compatibility

Designed as an OEM-replacement KSEM series replaceable tip for KSEM insert seat size 4 toolholders. Primary workpiece materials are steel (ISO P) and cast iron (ISO K).

Installation Notes

Installation of replaceable carbide drill tips should be performed by a qualified machinist with the spindle fully stopped and machine locked out. The tip seats into the KSEM holder body using the clamp-style holding method — ensure the seating surface is clean and free of chips before engaging the tip. Confirm coolant port alignment when through-coolant or MQL delivery is required. Refer to KENNAMETAL KSEM series setup documentation for clamping procedure specific to your holder body.
