Kennametal 2499868 Carbide Replaceable Tip Drill 25.67mm

Product Description

The KENNAMETAL 2499868 is a solid carbide replaceable tip drill in the KSEM series, designed for high-productivity hole-making in steel and cast iron. The drill tip carries a TiAlN coating applied via PVD process, providing thermal resistance and extended cutting life in demanding ferrous machining operations. The HPG insert geometry and 140-degree drill point angle support accurate entry and stable cutting at the tip. With a cutting diameter of 25.67 mm (1.0106 inches) and a flute length of 13.00 mm, this tool is suited for production drilling where consistent bore quality and tool change efficiency are priorities. It is installed by machinists and CNC operators in metalworking environments.

The KENNAMETAL 2499868 fits applications including standard through-hole drilling, inclined exit drilling, and stacked plate drilling. The through-coolant design supports minimum quantity lubrication (MQL) as well as conventional through-coolant delivery, keeping the cutting zone clear and extending tip life. The 2-flute, 2-margin configuration with helical flutes promotes chip evacuation in both shallow and moderate-depth holes. This tip is held in place by a clamp-style insert holding method using insert seat size 5, allowing rapid tip indexing without removing the drill body from the spindle.

Key Features

• Solid carbide fine-grain tip in KC7315 grade with TiAlN PVD coating for heat and wear resistance
• 140-degree standard drill point angle for accurate entry in steel and cast iron
• HPG insert geometry optimized for steel (ISO P) and cast iron (ISO K) workpiece materials
• Through-coolant channels compatible with MQL and conventional coolant delivery
• 2-flute helical design with 2-margin construction supports chip evacuation and bore finish
• Clamp-style tip retention with insert seat size 5 enables fast tip changes at the spindle
• Supports inclined exit drilling and stacked plate drilling applications

Compatibility

Designed for use with KSEM series drill bodies accepting insert seat size 5. Primary workpiece materials are steel (ISO P) and cast iron (ISO K). Compatible applications include standard drilling, inclined exit drilling, and stacked plate drilling as specified by the manufacturer.

Installation Notes

Tip installation and indexing should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine in a locked-out state. Use the correct KSEM clamp torque tool as specified by KENNAMETAL for the insert seat size to avoid tip movement or seat damage. Verify coolant channel alignment before resuming operations when using through-coolant or MQL delivery. Do not exceed the manufacturer-recommended cutting parameters for the KC7315 grade in the target workpiece material.
