Kennametal 2499765 Carbide Replaceable Tip Drill 18.5mm

Product Description

The KENNAMETAL 2499765 is a replaceable-tip drill from the KSEM series, designed for high-productivity drilling in steel and cast iron workpieces. The tip is manufactured from solid carbide in the KC7315 grade with a fine grain structure and a PVD-applied TiAlN coating, delivering strong wear resistance and thermal stability at the cutting edge. The drill features a 140-degree point angle, an HPG insert geometry, and a helical flute design with two flutes and two margins. Cutting diameter is 18.5mm (0.7283 inches). Through-spindle coolant is supported, including MQL (Minimum Quantity Lubrication), making this drill well suited for controlled-environment machining cells.

This replaceable-tip drill is intended for production drilling applications in ferrous materials, specifically steel (ISO material group P) and cast iron (ISO material group K). It is appropriate for standard through-drilling, inclined exit conditions, and stacked-plate configurations. The KSEM insert seat size 2 platform uses a clamp-style insert holding method, allowing the carbide tip to be swapped at the machine without disturbing the drill body. Typical users include CNC machinists and toolroom technicians in job shop and production manufacturing environments.

Key Features

• Solid carbide KC7315 grade tip with fine grain microstructure for extended tool life in ferrous materials
• TiAlN coating applied via PVD process for high-temperature wear resistance
• 140-degree standard point angle with HPG insert geometry
• Through-coolant and MQL compatible for chip evacuation and thermal management
• Two-flute helical design with two margins for improved hole straightness
• Clamp-style tip retention on KSEM insert seat size 2 body for quick tip changes at the spindle

Compatibility

The 2499765 tip is part of the KSEM series and fits KSEM insert seat size 2 drill bodies. It is rated for drilling in steel (ISO P) and cast iron (ISO K) workpiece materials. Compatible applications include standard drilling, inclined exit drilling, and stacked-plate drilling as specified by KENNAMETAL for the KSEM platform.

Installation Notes

Installation of replaceable carbide drill tips should be performed by a qualified machinist or toolroom technician with the spindle fully stopped and the machine locked out per facility safety procedures. Ensure the insert seat is clean and free of chips or debris before seating the tip, as contamination can cause tip misalignment and premature failure. Use the manufacturer-recommended torque tool or clamp key for the KSEM seat to secure the tip without over-tightening. Verify cutting diameter and runout with a tool presetter or dial indicator before initiating the first cut.
