Sumitomo 5KHZW0A Replaceable Drill Tip 0.6094 in ACX80

Product Description

The SUMITOMO 5KHZW0A is a replaceable drill tip designed for use with modular drill body systems. It is manufactured from solid carbide and carries the ACX80 grade designation within the SMD series. The tip features a MEL insert geometry and a 140-degree included angle, making it suitable for a wide range of workpiece materials. A PVD-applied TiAlCr and TiSi dual-layer coating enhances wear resistance and thermal stability during high-speed drilling operations. The cutting diameter is 0.6094 inches. Coolant-through capability is built in, supporting chip evacuation and heat management at the cutting zone. Licensed machinists and CNC machine operators are the primary installers of this insert type.

This replaceable drill tip is engineered for universal application across multiple material classifications, including cast iron, steel, stainless steel, and high-temperature alloys, corresponding to workpiece material codes K, M, P, and S. It is intended for use in modular drill systems that accept SMD-series replaceable tips. Typical deployment includes production drilling in CNC machining centers and horizontal boring mills where repeatable hole quality and quick tip changeover are priorities. The single-tip package format suits job-shop and maintenance environments where one tip per setup is standard practice.

Key Features

• Solid carbide construction in ACX80 grade for hardness and edge retention
• PVD-applied TiAlCr and TiSi dual-layer coating for thermal and wear resistance
• MEL insert geometry optimized for chip control across universal workpiece materials
• 140-degree included angle suits a broad range of drilling applications
• Coolant-through design supports chip evacuation and cutting-zone heat control
• SMD series compatibility enables fast tip replacement without removing the drill body

Compatibility

Designed as an OEM-style replaceable tip for modular drill body systems accepting SMD-series inserts with a 0.6094-inch cutting diameter.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool is secured before tip removal or installation. Mating surfaces on the drill body should be clean and free of chips or debris before seating the new tip. Follow the drill body manufacturer torque and seating specifications for the SMD series interface to prevent tip movement during operation.
