Sumitomo 5KHZW03 Carbide Replaceable Tip Drill ACX80 Smd

Product Description

The SUMITOMO 5KHZW03 is a solid carbide replaceable tip drill designed for high-performance hole-making in a wide range of workpiece materials. Part of the SMD series, this drill features a 140-degree included angle and a TiAlCr/TiSi PVD coating applied via physical vapor deposition. The MEL insert geometry and ACX80 manufacturer grade combine to deliver cutting stability and extended tool life. Through-coolant capability directs fluid directly to the cutting edge, managing heat and chip evacuation in demanding applications. Machinists and tooling engineers working in production environments will recognize this as a drop-in replaceable tip format, reducing downtime compared to full drill replacement.

The 5KHZW03 is suited for universal application across multiple workpiece material categories, including cast iron, steel, stainless steel, and high-temp alloys, as indicated by material codes K, M, P, and S. The replaceable tip design makes it practical for CNC machining centers and drilling stations where consistent hole quality and fast tip changeout are priorities. The through-coolant feature supports both flood and high-pressure coolant delivery setups.

Key Features

• Solid carbide tip with ACX80 grade for universal material compatibility
• TiAlCr and TiSi PVD coating for wear resistance and thermal protection
• 140-degree included angle suited for general-purpose drilling applications
• Through-coolant design for active heat management and chip flushing
• MEL insert geometry optimized for cutting stability
• Replaceable tip format reduces tooling cost and changeover time

Compatibility

Designed as an OEM-style replaceable tip for use within the Sumitomo SMD series drilling system. Compatible with workpiece materials classified under K, M, P, and S material codes, covering cast iron, steel, stainless steel, and superalloys.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or tooling technician. The spindle and machine tool must be fully powered down and locked out before tip removal or installation. Use the appropriate torque tool and holder specified for the SMD series body to seat the replaceable tip correctly. Do not exceed the recommended spindle speeds and feeds for the workpiece material category being machined.
