Kennametal 2499869 Carbide Replaceable Tip Drill Ksem

Product Description

The KENNAMETAL 2499869 is a carbide replaceable tip drill insert in the KSEM series, designed for high-productivity hole-making in metalworking applications. This HPG-geometry insert features a solid carbide construction with a PVD-applied TiAlN coating and a 140-degree drill point angle. It carries the KC7315 manufacturer grade, which is a fine-grain carbide grade suited for demanding cutting conditions. At 26.19mm (1.0311 inches) cutting diameter with a 13mm flute length, this insert fits KSEM-series drill bodies and is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is intended for drilling operations in steel and cast iron workpieces, covering ISO material codes P and K. The HPG geometry supports through-coolant and MQL (Minimum Quantity Lubricant) delivery, making it appropriate for inclined-exit drilling and stacked-plate applications. The helical, 2-flute, 2-margin configuration provides stable cutting action and chip evacuation in both through-hole and blind-hole scenarios. It is suited for CNC machining centers where rigid setups and controlled feed rates are maintained.

Key Features

• Solid carbide fine-grain construction with PVD TiAlN coating for heat and wear resistance
• 140-degree drill point angle for reduced thrust force and accurate hole entry
• HPG insert geometry with 2-flute, 2-margin design for stable cutting and chip control
• Through-coolant and MQL-compatible for extended tool life in steel and cast iron
• Clamp-style insert holding in KSEM-series drill bodies, Insert Seat Size 6
• Supports inclined-exit and stacked-plate drilling operations

Compatibility

Designed for use with KSEM-series replaceable tip drill bodies that accept Insert Seat Size 6. Compatible with primary workpiece materials including steel (ISO code P) and cast iron (ISO code K).

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on CNC or manual machine tools. Power down and lock out the machine spindle before seating or removing the insert. Use the manufacturer-specified clamping torque tool and procedure for the KSEM insert seat to ensure proper seating and prevent insert movement under cutting loads. Verify coolant channel alignment when through-coolant or MQL delivery is required before returning the tool to service.
