Kennametal 2499852 Carbide Replaceable Tip Drill 18.26mm

Product Description

The KENNAMETAL 2499852 is a solid carbide replaceable tip drill from the KSEM series, designed for high-productivity hole-making in steel and cast iron. The tip carries Kennametal grade KC7315 with a PVD-applied TiAlN coating and an HPG insert geometry, delivering wear resistance and thermal stability in demanding metal-cutting operations. The drill features a 140-degree point angle, two helical flutes with two margins, and integrated through-coolant capability including MQL (Minimum Quantity Lubricant) support. Cutting diameter is 18.26 mm (0.7189 inches). This tool is installed and operated by machinists and toolroom technicians working on CNC vertical or horizontal machining centers.

The KSEM series replaceable tip system is suited for production drilling in job shop and manufacturing environments where rapid tip changes without full tool removal are required. Typical applications include straight drilling, inclined-surface entry and exit, and stacked-plate drilling. The HPG geometry and fine-grain carbide substrate support consistent hole quality in P-group steels and K-group cast irons. Through-coolant delivery keeps cutting temperatures controlled during deep-entry passes.

Key Features

• Solid carbide tip with KC7315 fine-grain grade and PVD TiAlN coating for wear and heat resistance
• 140-degree standard point angle suited for steel and cast iron entry
• HPG insert geometry with 2-flute, 2-margin configuration for stable chip evacuation
• Through-coolant and MQL compatible via internal coolant channels
• Clamp-style insert holding for secure tip retention under high feed loads
• Rated for inclined-exit and stacked-plate drilling applications

Compatibility

Designed for use with KSEM series insert seat size 2 drill bodies. Compatible workpiece materials include P-group steels and K-group cast irons per ISO material classification.

Installation Notes

Installation and tip changes should be performed by qualified machinists with the spindle fully stopped and the machine in a locked-out state. Use the correct KSEM clamping wrench and follow the tool body manufacturer torque guidance for the insert seat size 2 interface. Verify coolant port alignment before resuming through-coolant operation. Do not exceed the cutting parameters specified in the Kennametal KSEM application guide for the workpiece material group.
