Sumitomo 5KHZW0B Carbide Replaceable Tip Drill Smd ACX80

Product Description

The SUMITOMO 5KHZW0B is a carbide replaceable tip drill from the SMD Series, engineered for high-performance drilling in a wide range of workpiece materials. It features a 0.625 inch (15.88 mm) cutting diameter, a 140-degree included angle, and a TiAlCr/TiSi dual coating that improves wear resistance and surface hardness. The ACX80 grade solid carbide tip is designed for universal material application, covering ferrous, non-ferrous, stainless, and superalloy workpieces. Through-coolant capability delivers coolant directly to the cutting edge, extending tool life and improving chip evacuation at higher feed rates. This drill is used by machinists and tool-and-die professionals in production and job-shop environments.

The 5KHZW0B is suited for drilling operations in materials classified under workpiece codes K, M, P, and S, covering cast iron, steel, stainless steel, and heat-resistant superalloys. The MEL insert geometry supports stable entry and consistent hole quality across these material groups. It is appropriate for use on CNC machining centers and production drilling equipment where through-coolant supply is available. Typical applications include component manufacturing in aerospace, automotive, and general engineering where repeatable hole geometry and dimensional accuracy are required.

Key Features

• 0.625 inch cutting diameter with 15.88 mm metric equivalent for dual-standard shop use
• TiAlCr and TiSi dual coating improves thermal resistance and extends tool life in abrasive and high-temp materials
• Through-coolant design channels fluid directly to the cutting zone for improved chip evacuation and reduced heat buildup
• 140-degree included angle supports clean entry geometry across universal workpiece material classifications
• ACX80 grade solid carbide tip for consistent performance in K, M, P, and S material groups
• Replaceable tip design reduces tooling cost compared to solid carbide drills by allowing tip exchange without discarding the drill body

Compatibility

Designed for use in SMD Series replaceable tip drill bodies. Compatible with workpiece materials classified as K (cast iron), M (stainless steel), P (steel), and S (heat-resistant superalloys) per ISO material classification. Requires a through-coolant capable machine spindle for optimal performance.

Installation Notes

Installation of replaceable tip drills should be performed by a qualified machinist following the tool manufacturer's torque and seating procedures for the SMD Series body. Ensure the machine spindle and coolant supply are fully shut down before tip exchange. Inspect the drill body seating surface for chips or damage before installing a new tip. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drilling equipment.
