Kennametal 2499846 Carbide Replaceable Tip Drill 16.09mm

Product Description

The KENNAMETAL 2499846 is a solid carbide replaceable tip drill in the KSEM series, designed for high-productivity hole-making in steel and cast iron. The tip carries a TiAlN coating applied via PVD process, offering strong wear resistance and thermal stability under demanding cutting conditions. The HPG insert geometry paired with Manufacturer Grade KC7315 fine-grain carbide delivers consistent edge integrity across production drilling cycles. With a 16.09mm cutting diameter, a 140-degree drill point angle, and through-coolant capability including MQL support, this tip is built for precision drilling in environments where tool life and hole quality are both critical.

This replaceable tip drill is suited for industrial machining applications including straight drilling, inclined-exit drilling, and stacked-plate drilling. The KSEM platform uses a clamp-style insert holding method with a Size 1 insert seat, allowing tip replacement without removing the body from the tool holder. Primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K), making this a versatile option for job shops and production machining cells running ferrous materials.

Key Features

• Solid carbide tip with TiAlN PVD coating for wear resistance in steel and cast iron
• KC7315 fine-grain carbide grade engineered for stability in P and K material groups
• HPG insert geometry with 140-degree drill point angle for accurate entry and reduced thrust
• Through-coolant design compatible with both flood coolant and MQL delivery
• Helical flute, regular spiral, 2-flute 2-margin configuration for chip evacuation and hole quality
• Clamp-style retention in KSEM body for repeatable tip indexing

Compatibility

Designed for use with KSEM series drill bodies accepting a Size 1 insert seat. The ISO number for this tip is KSEM0634HPG. Compatible applications include straight drilling, inclined-exit drilling, and stacked-plate drilling in steel and cast iron workpieces.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before seating or removing the replaceable tip. Use the appropriate KSEM torx or clamping key as specified by the tool body manufacturer to achieve correct clamp engagement. Do not exceed the tool body speed and feed recommendations for the 16.09mm diameter range.
