Kennametal 3381151 Ksem Replaceable Tip Drill 0.7587 in

Product Description

The KENNAMETAL 3381151 is a carbide replaceable tip drill in the KSEM series, designed for precision hole-making in demanding machining environments. This drill uses the HPL insert geometry with an AlTiN PVD coating and a 140-degree drill point angle, making it well-suited for high-productivity drilling in steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. The cutting diameter is 0.7587 inches (19.27mm), and the solid carbide tip is held in place by a clamp-style insert seat. Machinists and tool-and-die professionals install this as a modular, cost-efficient alternative to solid-body drills, replacing only the worn tip rather than the full tool body.

The KENNAMETAL 3381151 is intended for use in CNC machining centers and drilling operations across a broad range of workpiece materials. The helical, two-flute, two-margin configuration with regular spiral geometry supports chip evacuation and hole quality on entry and exit. This drill is rated for inclined exit drilling and stacked plate drilling applications, giving it flexibility across production and job-shop environments handling steel and exotic alloy components. It does not include through-coolant capability, so external or flood coolant delivery should be planned accordingly.

Key Features

• Solid carbide HPL tip in KSEM series insert seat size 2 for repeatable tool change without body replacement
• AlTiN PVD coating provides heat and wear resistance when drilling steel, stainless steel, and superalloys
• 140-degree drill point angle suited for flat-bottom entry and clean hole geometry
• Two-flute, two-margin helical design supports chip control and bore surface finish
• Rated for inclined exit and stacked plate drilling applications
• Fine grain carbide substrate under KCMS15 manufacturer grade for edge toughness in interrupted and difficult cuts

Compatibility

Designed for use with KSEM series replaceable tip drill bodies accepting insert seat size 2. Compatible workpiece materials include steel (ISO P), stainless steel (ISO M), cast iron (ISO K), non-ferrous metals (ISO N), and superalloys and titanium (ISO S).

Installation Notes

This tip is installed and removed by a qualified machinist or toolroom technician using the appropriate KSEM clamp torque tool as specified by the tool body documentation. Power down and lock out the machine spindle before changing the insert tip. Do not exceed the drill body manufacturer's recommended speed and feed parameters for the given workpiece material and insert grade. External or flood coolant is required since this tip does not support through-coolant delivery.
