Kennametal 2499855 Carbide Replaceable Tip Drill Ksem KC7315

Product Description

The KENNAMETAL 2499855 is a solid carbide replaceable tip drill insert designed for the KSEM modular drilling system. Carrying the KC7315 manufacturer grade and a fine-grain carbide substrate, this insert delivers a 19.27mm (0.7587 inch) cutting diameter with a 140-degree drill point angle. The TiAlN coating is applied via PVD process, providing thermal resistance and wear life in demanding cutting operations. It features a helical, 2-flute, 2-margin geometry with through-coolant capability, including support for MQL (Minimum Quantity Lubrication). Licensed HVAC techs, plumbers, and machinists working with production drilling setups will recognize this as a precision consumable for high-throughput applications.

This replaceable tip is suited for drilling into steel and cast iron workpieces, covering ISO material codes P and K. The HPG insert geometry and regular spiral flute design make it effective for inclined exit drilling, stacked plate drilling, and standard through-hole operations. It is clamp-held into compatible KSEM drill bodies, making tip changes fast without removing the full tool from the spindle. Both residential-scale job shops and commercial machining operations use KSEM-style systems to reduce per-hole tooling cost on repetitive drilling programs.

Key Features

• Solid carbide fine-grain substrate with KC7315 grade for wear resistance in steel and cast iron
• TiAlN coating via PVD process for thermal protection at elevated cutting speeds
• 19.27mm cutting diameter with 140-degree standard drill point angle
• 2-flute, 2-margin, helical flute design with through-coolant and MQL support
• HPG insert geometry supports inclined exit and stacked plate drilling applications
• Clamp-held seating in KSEM system bodies for rapid tip replacement without full tool removal

Compatibility

Designed for use with compatible KSEM series modular drill bodies accepting Insert Seat Size 2. Primary workpiece materials are steel (ISO P) and cast iron (ISO K).

Installation Notes

Installation of replaceable carbide tip inserts should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate KSEM clamp torque tool as specified by the drill body manufacturer - do not substitute with general-purpose wrenches that may under- or over-seat the clamp. Verify coolant channel alignment when through-coolant or MQL delivery is required before returning the tool to service.
