Kennametal 2499763 Carbide Replaceable Tip Drill 18mm

Product Description

The KENNAMETAL 2499763 is a carbide replaceable tip drill from the KSEM series, designed for high-productivity hole-making in steel and cast iron. The tip features a solid carbide construction with a KC7315 fine-grain substrate and a PVD-applied TiAlN coating that resists heat and wear in demanding cutting conditions. The 140-degree drill point angle and HPG insert geometry promote self-centering and chip control. With a cutting diameter of 18mm (0.7087 inches) and through-coolant capability including MQL support, this insert is built for machine shop and production environments where consistency and tool life matter. Licensed machinists and CNC operators are the primary users.

This replaceable tip drill insert is suited for drilling operations in ferrous materials, specifically steel (ISO material code P) and cast iron (ISO material code K). It fits applications involving standard through-hole drilling, inclined exit drilling, and stacked plate drilling. The 2-flute, 2-margin helical flute design and clamp-style insert holding method make it appropriate for CNC machining centers running high-volume production cycles. The through-coolant channels support both flood coolant and minimum quantity lubrication delivery.

Key Features

• Solid carbide KC7315 fine-grain substrate for wear resistance in steel and cast iron
• PVD TiAlN coating reduces thermal load and extends tool life
• 140-degree drill point angle for accurate self-centering entry
• HPG insert geometry with 2-flute, 2-margin helical configuration for chip evacuation
• Through-coolant design compatible with flood coolant and MQL systems
• Supports inclined exit and stacked plate drilling applications

Compatibility

Designed for use with KSEM series replaceable tip drill bodies accepting insert seat size 1. Primary workpiece materials are steel (ISO code P) and cast iron (ISO code K).

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Follow the tool body manufacturer torque guidelines for the clamp holding method when seating the replaceable tip. Verify coolant port alignment before running to ensure proper through-coolant flow. Confirm insert seat cleanliness and freedom from chips or debris before clamping to maintain runout accuracy.
