Kennametal 2047420 Replaceable Tip Drill 47/64 in KC7315

Product Description

The KENNAMETAL 2047420 is a solid carbide replaceable tip drill insert in the KSEM series, designed for precision hole-making in steel and similar workpieces. Manufactured in grade KC7315 with a PVD-applied TiAlN coating, it delivers wear resistance and thermal stability during high-feed drilling operations. The insert features a 47/64 inch (18.65 mm) cutting diameter, a 140-degree drill point angle, and a helical two-flute geometry with two margins. It is installed by licensed machinists and tool-and-die professionals using the KSEM modular drill body system. The clamp-held seating method ensures secure retention and repeatable positioning at the cutting tip.

This replaceable tip insert is suited for drilling operations in steel across a range of manufacturing and machining environments. Its HP insert geometry is optimized for inclined-exit drilling and stacked-plate applications where conventional solid drills present challenges. The 140-degree point angle supports clean entry and controlled chip formation in ferrous materials. With a functional length of 0.367 inches and a flute length of 9.00 mm, it is intended for shallow-to-moderate depth drilling at the tip position of the KSEM modular shank. Seat size 2 identifies the correct KSEM body required for installation.

Key Features

• Solid carbide fine-grain substrate in manufacturer grade KC7315 for toughness in steel cutting
• PVD TiAlN coating for high-temperature wear resistance and extended tool life
• 140-degree standard drill point angle for controlled entry and exit in ferrous workpieces
• Two-flute helical design with two margins for stable drilling and accurate hole geometry
• HP insert geometry rated for inclined-exit and stacked-plate drilling applications
• Clamp-held retention in KSEM insert seat size 2 shank bodies

Compatibility

Designed for use with KSEM modular drill bodies accepting insert seat size 2. Primary workpiece material is steel (ISO material code P). ISO number KSEM0734HP identifies this insert within the KSEM series.

Installation Notes

Installation is performed by qualified machinists following the toolholder manufacturer torque and clamping specifications for KSEM seat size 2 bodies. Ensure the spindle is fully stopped and machine power is locked out before seating or removing the replaceable tip. Inspect the insert seat for debris or damage before installation to maintain runout accuracy. This insert does not include internal coolant-through capability; external coolant delivery should be confirmed at the machine setup stage.
