Kennametal 2499853 Carbide Replaceable Tip Drill 47/64 in

Product Description

The KENNAMETAL 2499853 is a solid carbide replaceable tip drill in the KSEM series, designed for high-performance drilling in steel and cast iron. It carries the KSEM0734HPG ISO number and is manufactured to Kennametal grade KC7315 using fine-grain carbide with a PVD-applied TiAlN coating. The cutting diameter is 47/64 inches (0.7343 inches, 18.65mm), with a 140-degree drill point angle and a 2-flute helical configuration. It incorporates through-coolant capability, including support for minimum quantity lubrication (MQL). This tip is installed by machinists and tooling technicians in production drilling environments requiring repeatable accuracy and extended tool life.

This replaceable tip drill is suited for drilling operations in steel and cast iron workpieces, matching ISO material groups P and K. Typical applications include straight drilling, inclined exit drilling, and stacked-plate drilling. The HPG insert geometry combined with a regular spiral and 2-flute, 2-margin design supports chip evacuation and hole quality in demanding production setups. The clamp-style insert holding method ensures secure tip retention during high-feed operations. It is appropriate for both flood coolant and MQL through-coolant setups on CNC machining centers.

Key Features

• Solid carbide fine-grain tip with PVD TiAlN coating for extended tool life in ferrous materials
• 140-degree drill point angle with HPG insert geometry for efficient entry and reduced thrust
• Through-coolant design supports both flood and MQL delivery methods
• 2-flute, 2-margin helical configuration promotes chip evacuation and bore accuracy
• Clamp-style insert holding secures tip under high-feed and interrupted-cut conditions
• Compatible with inclined exit and stacked-plate drilling applications

Compatibility

Designed for use with KSEM series drill bodies accepting insert seat size 2. Primary workpiece materials are steel (ISO group P) and cast iron (ISO group K).

Installation Notes

Installation and tip changes are performed by qualified machinists or tooling technicians. Ensure the drill body is fully secured in the spindle and the machine is powered down and locked out before replacing the insert tip. Use the appropriate torque tool for the clamp screw as specified by the drill body documentation. Verify through-coolant passages are clear before resuming operations.
