Sumitomo 5KHZW0E Carbide Replaceable Tip Drill 43/64 in

Product Description

The SUMITOMO 5KHZW0E is a carbide replaceable tip drill in the SMD Series, designed for high-performance metal cutting across a broad range of workpiece materials. The tip is manufactured from solid carbide with an ACX80 grade designation and coated via PVD process with a TiAlCr and TiSi finish for extended wear resistance and thermal stability. The drill features a 140-degree included point angle and a 43/64-inch diameter cutting tip. Through-coolant capability supports chip evacuation and heat management during deep-hole and high-speed drilling operations. This tool is installed and changed out by machinists and tool-room technicians in production or job-shop environments.

The 5KHZW0E is suited for universal application across multiple workpiece material categories, including cast iron, steel, stainless steel, and superalloys, as indicated by the K, M, P, and S material codes. The MEL insert geometry is specific to the SMD replaceable tip system. The through-coolant design makes it appropriate for CNC machining centers where coolant delivery is available through the spindle. Typical applications include precision drilling in automotive, aerospace, and general metalworking production environments where consistent hole quality and tool life are priorities.

Key Features

• Solid carbide replaceable tip in ACX80 grade for consistent cutting performance
• TiAlCr and TiSi PVD coating provides thermal resistance and extended tool life
• 140-degree included point angle suited for universal drilling applications
• 43/64-inch diameter cutting tip in SMD Series platform
• Through-coolant design supports chip evacuation and heat control at the cutting zone
• Compatible with K, M, P, and S workpiece material categories

Compatibility

The 5KHZW0E is a replaceable tip drill in the SUMITOMO SMD Series and is designed to be used with compatible SMD Series drill bodies that accept the MEL insert geometry in 43/64-inch diameter sizing.

Installation Notes

Replaceable tip drills in the SMD Series are installed and serviced by qualified machinists or CNC setup technicians. The drill body must be secured in the spindle and fully stopped before tip replacement. Use the correct torque tool recommended by the manufacturer for tip seating — do not overtighten by hand or with improvised tools. Verify through-coolant connections are clear and functioning before resuming operation.
