Kennametal 2499849 Replaceable Tip Drill 17.07mm KC7315

Product Description

The KENNAMETAL 2499849 is a carbide replaceable tip drill from the KSEM series, engineered for high-productivity hole-making in steel and cast iron. The insert tip carries the ISO designation KSEM0672HPG and is manufactured in a fine grain solid carbide substrate with a PVD-applied TiAlN coating. The cutting diameter measures 43/64 inch (0.6720 inch / 17.07mm) and the drill point is ground to a 140-degree included angle. Two helical flutes and a standard point geometry provide chip control and stable entry. Through-coolant capability supports both flood and MQL (minimum quantity lubricant) delivery. Licensed HVAC, plumbing, or machine tool technicians and machinists performing precision drilling operations are the primary users.

This replaceable tip drill is suited for drilling operations in steel and cast iron workpieces in production machining environments. The HPG insert geometry is specifically designed to handle inclined exit surfaces, stacked plate configurations, and conventional straight-through drilling. The KC7315 grade and TiAlN finish are optimized for ISO material groups P (steel) and K (cast iron). The KSEM insert seat size 1 body accepts a clamped insert, allowing tip replacement without discarding the shank body, which reduces per-hole tooling cost in repeat production runs.

Key Features

• Solid carbide fine grain substrate with PVD TiAlN coating for extended tool life in steel and cast iron
• 140-degree drill point angle with standard point type for accurate hole entry and exit
• Through-coolant channels compatible with flood coolant and MQL systems
• HPG insert geometry rated for inclined exit surfaces and stacked plate drilling
• Replaceable tip design: KSEM insert seat size 1, clamp-held, preserves shank for reuse
• Two helical flutes with regular spiral and 2-margin configuration for chip evacuation

Compatibility

Designed as an OEM-style replaceable tip for KSEM series insert seat size 1 drill bodies. Compatible workpiece materials include steel (ISO P) and cast iron (ISO K) per manufacturer specification.

Installation Notes

Replaceable tip drills of this type are installed and serviced by machinists or tooling technicians using the appropriate KSEM torx or clamping key specified for the insert seat. Ensure the spindle is fully powered down and the machine is in a safe lockout state before replacing the insert tip. Seat the insert fully and verify clamp engagement before resuming cutting operations. Confirm coolant port alignment when through-coolant is in use to prevent restricted flow and premature tool failure.
