Kennametal 2499861 Carbide Replaceable Tip Drill Ksem

Product Description

The KENNAMETAL 2499861 is a carbide replaceable tip drill in the KSEM series, designed for high-productivity hole-making in steel and cast iron applications. The drill accepts an KSEM0859HPG solid carbide insert tip with a KC7315 grade and TiAlN PVD coating, delivering heat and wear resistance suited to demanding production environments. The cutting diameter measures 55/64 inch (0.8594 inch / 21.83 millimeters), and the drill point angle is 140 degrees. With through-coolant capability and support for minimum quantity lubrication (MQL), this tool is built for shops running modern machining centers where coolant delivery through the spindle is standard practice.

This drill is intended for metalworking applications in industrial and production machining environments. It is suited for drilling straight-entry holes as well as inclined exits and stacked plate configurations. Primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K). The HPG insert geometry and regular spiral flute design support chip evacuation in these material groups. Two flutes with two margins provide stable guidance during drilling. Typical users include CNC machinists and toolroom professionals working in job shop or production settings.

Key Features

• Solid carbide KSEM0859HPG replaceable tip insert - no regrinding required, tip swaps in the field
• KC7315 grade with TiAlN PVD coating for elevated wear resistance in steel and cast iron
• 140-degree drill point angle suits a wide range of entry and exit conditions including inclined surfaces
• Through-coolant design with MQL compatibility supports high-speed, low-waste machining strategies
• HPG insert geometry with regular helical spiral and 2-flute / 2-margin configuration for stable chip control
• Insert seat size 3 with clamp holding method for secure, repeatable tip positioning

Compatibility

Designed for use with KSEM series replaceable tip drill bodies accepting insert seat size 3. Compatible insert ISO number is KSEM0859HPG in KC7315 grade. Intended for primary workpiece materials steel (P) and cast iron (K) per ISO material classification.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle fully stopped. Follow the tool body manufacturer torque guidance for the clamp screw when seating the replaceable tip. Verify coolant passages are clear before returning the tool to service when through-coolant or MQL delivery is used. Inspect the insert seat for debris or wear at each tip change to maintain dimensional accuracy.
