Sumitomo 5KHZW11 Carbide Replaceable Tip Drill ACX80

Product Description

The SUMITOMO 5KHZW11 is a carbide replaceable tip drill in the SMD series, designed for high-performance hole-making in a wide range of workpiece materials. This drill features a 140-degree point angle and an MEL insert geometry, making it well suited for fast, accurate penetration across multiple material types. The TiAlCr and TiSi coatings are applied via PVD process, providing thermal resistance and wear protection during demanding cutting operations. The through-coolant design channels cutting fluid directly to the tip, improving chip evacuation and extending tool life. Machinists and tooling technicians in production environments will find this drill a reliable choice for high-volume drilling applications.

The 5KHZW11 carries a universal primary workpiece material classification, covering material groups K, M, P, and S — which correspond to cast iron, stainless steel, steel, and superalloys respectively. This versatility makes it a practical drill tip for shops that machine a variety of ferrous and non-ferrous materials. The replaceable tip design allows the carbide tip to be swapped out without replacing the drill body, reducing tooling cost per hole and minimizing downtime during production runs. It is typically installed by machinists and CNC operators working with machining centers and drill presses equipped for through-spindle coolant delivery.

Key Features

• ACX80 manufacturer grade carbide for extended wear resistance in demanding cuts
• 140-degree point angle with MEL insert geometry for accurate entry and reduced thrust force
• TiAlCr and TiSi PVD coating for thermal stability and surface hardness
• Through-coolant design for active chip evacuation and tip cooling
• Replaceable tip system reduces total tooling cost compared to solid drill replacement
• Universal workpiece material compatibility across K, M, P, and S material groups

Compatibility

Designed for use in SMD-series drill bodies that accept MEL-geometry replaceable carbide tips with through-coolant capability.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the drill body is clean and free of debris before seating the replaceable tip, and confirm the tip is fully engaged and torqued to the tool manufacturer's specification using the correct wrench. Power down and lock out any machine spindle before performing tip changes. Verify that the machine's through-spindle coolant system is compatible and that coolant pressure is within the range recommended for the drill body series.
