Kennametal 3381132 Replaceable Tip Drill 43/64 Ksem

Product Description

The KENNAMETAL 3381132 is a solid carbide replaceable tip drill insert in the KSEM series, designed for use with compatible KSEM modular drill bodies. Carrying the ISO designation KSEM0672HPL, this insert features a 17.07 mm (43/64 inch) cutting diameter, a 140-degree drill point angle, and an AlTiN (aluminum titanium nitride) coating applied via PVD process. The HPL insert geometry and fine grain carbide substrate in manufacturer grade KCMS15 make this tip suited for demanding drilling operations. Licensed machinists and CNC operators in production and job shop environments are the primary installers.

This replaceable tip drill insert is intended for drilling operations in a range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, and superalloys and titanium (ISO material codes P, M, K, N, and S). Typical applications include standard through-hole drilling, drilling on inclined exit surfaces, and drilling through stacked plates. The 2-flute, 2-margin, regular spiral helical flute configuration promotes chip evacuation and hole quality across these material groups. It is suited for both horizontal and vertical machining center setups in light to heavy production environments.

Key Features

• Solid carbide tip in fine grain KCMS15 grade for wear resistance across multiple material groups
• AlTiN PVD coating for thermal resistance and extended tool life in ferrous and difficult-to-machine materials
• 140-degree drill point angle suitable for standard entry and inclined exit drilling
• 2-flute, 2-margin helical flute design promotes chip clearance and hole accuracy
• Clamp-style insert holding method for secure, repeatable seating in the KSEM drill body
• Supports stacked plate and inclined exit drilling applications

Compatibility

Designed for use with KSEM series modular drill bodies accepting insert seat size 1 with a 17.07 mm cutting diameter. Specific compatible drill body part numbers were not provided in the available product data; verify seat size and series designation against the KSEM body in use before ordering.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and the tool holder secured before seating or removing the replaceable tip. Use the appropriate KSEM torque key or clamping tool for the clamp-style holding method; do not use improvised tools that could damage the insert seat or clamp. Verify coolant delivery setup prior to use, as this insert does not include internal coolant-through capability.
