Sumitomo 5KHZ226 Carbide Replaceable Tip Drill 15mm ACX80

Product Description

The SUMITOMO 5KHZ226 is a solid carbide replaceable tip drill from the SMD Series, designed for high-performance hole-making in a wide range of workpiece materials. The drill features a 15mm diameter with a 140-degree included point angle and an MEL insert geometry for efficient chip evacuation and accurate entry. A PVD-applied TiAlCr and TiSi dual-coating finish provides thermal resistance and extended edge life under demanding cutting conditions. Through-coolant capability delivers coolant directly to the cutting zone, reducing heat buildup and supporting longer tool life at elevated feed rates.

The 5KHZ226 is suited for universal application across multiple workpiece material categories, including cast iron, stainless steel, carbon steel, and superalloys as indicated by the K, M, P, and S material codes. The replaceable tip design of the SMD Series makes it a practical choice for production machining environments where tip replacement is preferred over full tool replacement. It is used in CNC machining centers in both job shop and high-volume manufacturing settings.

Key Features

• Solid carbide tip with ACX80 manufacturer grade for wear resistance in demanding materials
• TiAlCr and TiSi PVD coating provides thermal stability and reduced friction at the cutting edge
• 140-degree included point angle with MEL geometry for controlled entry and chip flow
• Through-coolant design channels coolant directly to the cutting tip
• Replaceable tip configuration reduces tooling cost compared to full solid carbide drills
• Compatible with universal workpiece material categories K, M, P, and S

Compatibility

Designed for use in SMD Series replaceable tip drill bodies that accept the MEL insert geometry. Workpiece material compatibility spans K, M, P, and S material codes as specified by the manufacturer.

Installation Notes

Installation of the replaceable tip should be performed by a qualified machinist following the tool manufacturer's torque and seating procedures for SMD Series bodies. Ensure the drill body shank and tip pocket are clean and free of chips before seating the tip. Confirm through-coolant supply pressure and flow rate are adequate for the cutting application before commencing drilling. Proper tool holder runout should be verified to maximize tip life and hole quality.
