Kennametal 2499753 Carbide Replaceable Tip Drill 16mm Ksem

Product Description

The KENNAMETAL 2499753 is a replaceable-tip carbide drill from the KSEM series, designed for high-productivity hole-making in steel and cast iron. It uses a solid carbide tip in the KSEM1600HPGM geometry, held by a clamping mechanism and coated with TiAlN via a PVD process. The 140-degree drill point angle and helical fluting support efficient chip evacuation, while through-coolant capability — including MQL (Minimum Quantity Lubrication) compatibility — helps manage heat at the cutting zone. The tip measures 16mm (0.6299 inches) in cutting diameter and is suited for production environments where insert changeability reduces downtime.

This drill is intended for use in steel (ISO material group P) and cast iron (ISO material group K) workpieces. The KSEM platform is well suited for CNC machining centers and turning centers in industrial manufacturing environments. The HPG insert geometry and KC7315 fine-grain carbide grade make this configuration appropriate for applications including standard drilling, inclined exit drilling, and stacked plate drilling. A licensed machinist or CNC setup technician is the typical end user.

Key Features

• Solid carbide KSEM replaceable tip — no regrinding required, fast tip exchange at the machine
• TiAlN PVD coating improves wear resistance in steel and cast iron
• 140-degree included angle with standard point geometry for accurate entry and exit
• Through-coolant and MQL-ready for extended tool life in high-feed applications
• 2-flute, 2-margin helical design supports chip flow and bore straightness
• Compatible with inclined exit and stacked plate drilling operations

Compatibility

Designed for use with KSEM series drill bodies accepting Insert Seat Size 1. Compatible primary workpiece materials are steel (ISO code P) and cast iron (ISO code K). Refer to the KSEM system toolholder specifications to confirm body-to-tip compatibility before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the replaceable tip. Use the appropriate KSEM clamping tool to secure the insert to the specified holding method — do not overtighten with non-standard tools. Verify through-coolant port alignment with the machine spindle before running the drill at operating parameters.
