Sumitomo 5KHZ227 Carbide Replaceable Tip Drill 15.5mm ACX80

Product Description

The SUMITOMO 5KHZ227 is a carbide replaceable tip drill from the SMD Series, designed for high-performance hole-making in a wide range of workpiece materials. It features a 15.5mm (0.6102 inch) cutting diameter, a 140-degree included angle, and a MEL insert geometry. The tip is manufactured from solid carbide with an ACX80 grade designation and coated via a PVD process with a dual TiAlCr and TiSi finish. Through-coolant capability supports chip evacuation and heat management during drilling operations. This drill is intended for installation and use by machining and tooling professionals in production environments.

The 5KHZ227 is rated for universal primary workpiece material compatibility, covering material codes K, M, P, and S. This makes it suitable for cast iron, steel, stainless steel, and certain superalloys depending on feeds and speeds. It is a practical choice for shops running a variety of materials on CNC machining centers or drill presses where a single replaceable tip drill needs to handle multiple job types without a dedicated specialty grade.

Key Features

• Solid carbide replaceable tip in ACX80 grade for extended tool life
• Dual TiAlCr and TiSi PVD coating for heat and wear resistance
• 140-degree included angle with MEL geometry for controlled entry and chip formation
• Through-coolant design aids chip evacuation and reduces heat buildup at the cutting zone
• Universal material compatibility across K, M, P, and S workpiece classifications

Compatibility

Designed as a replaceable tip drill in the SMD Series, compatible with standard SMD Series drill bodies accepting 15.5mm MEL geometry tip inserts.

Installation Notes

Replaceable tip drills in this series are installed and changed by machining technicians following the tool manufacturer's torque and seating procedures for SMD tip retention. Ensure the drill body shank and tip pocket are clean and free of chips before seating the tip. Through-coolant connections should be verified for alignment and pressure before resuming operation. Always confirm spindle speed and feed rate parameters against appropriate cutting data before engaging the workpiece.
