Kennametal 2499859 Carbide Replaceable Tip Drill Ksem KC7315

Product Description

The KENNAMETAL 2499859 is a carbide replaceable tip drill in the KSEM series, designed for high-productivity hole-making in steel and cast iron. The tip features a solid carbide construction with a TiAlN PVD coating and HPG insert geometry, delivering consistent cutting performance in demanding machining environments. At 20.64mm (0.8126 inches) cutting diameter, a 140-degree drill point angle, and a 2-flute helical configuration with through-coolant capability, this drill is built for precision and chip control in both roughing and finishing drilling operations. It is intended for installation by machinists and tooling specialists in CNC and manual drilling applications.

This replaceable tip drill is suited for drilling operations in steel and cast iron workpieces across a range of production environments. Its through-coolant design supports minimum quantity lubrication (MQL) as well as full through-coolant delivery, making it adaptable for inclined exit drilling, stacked plate drilling, and standard through-hole applications. The clamp-style insert holding method ensures secure tip retention during high-feed or high-speed operations. The KSEM series platform is a modular system that accepts KSEM-compatible tip seats, reducing tooling changeover time in production settings.

Key Features

• Solid carbide tip with TiAlN PVD coating for wear resistance in steel and cast iron
• HPG insert geometry for improved chip formation and hole quality
• 140-degree drill point angle suits a wide range of workpiece materials and entry conditions
• Through-coolant design compatible with MQL and standard coolant delivery
• 2-flute helical configuration with 2-margin design for bore accuracy
• Clamp-style insert holding for positive tip location and repeatable sizing
• Rated for inclined exit drilling and stacked plate applications

Compatibility

Designed for use with KSEM series insert seat size 3 drill bodies. Primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K). ISO number KSEM0813HPG. Compatible with KSEM-platform tooling systems that accept this seat size.

Installation Notes

Installation and tip changes should be performed by a qualified machinist with the machine in a full stop and lockout/tagout applied per shop safety protocols. Seat contact surfaces should be inspected and cleaned before seating the replaceable tip to ensure accurate tip location and prevent premature wear. Verify coolant port alignment when through-coolant delivery is required. Do not exceed manufacturer-recommended cutting parameters for the KC7315 grade in the material being machined.
