Sumitomo 5KHZW1G Carbide Replaceable Tip Drill 19.25mm ACX80

Product Description

The SUMITOMO 5KHZW1G is a carbide replaceable tip drill in the SMD series, designed for high-performance metal cutting across a broad range of workpiece materials. The drill features an ACX80 grade solid carbide tip with a dual PVD coating of TiAlCr and TiSi, delivering enhanced heat resistance and wear life at elevated cutting speeds. The 140-degree included angle suits general-purpose drilling applications. Through-coolant capability directs cutting fluid to the tip, extending tool life and improving chip evacuation. This tool is installed and operated by machinists and CNC tooling specialists in production and job-shop environments.

The 5KHZW1G is suited for drilling operations on universal workpiece materials, including cast iron (K), stainless and heat-resistant alloys (M/S), and steel (P). The SMD replaceable tip platform allows tip indexing without removing the drill body from the spindle, reducing downtime in high-volume production. Typical applications include through-hole and blind-hole drilling on CNC machining centers and turning centers equipped with through-spindle coolant delivery.

Key Features

• ACX80 grade solid carbide replaceable tip for consistent cutting performance
• Dual PVD coating — TiAlCr and TiSi — for heat resistance and extended tool life
• 140-degree point angle for general-purpose drilling geometry
• Through-coolant design improves chip evacuation and tip cooling
• MEL insert geometry optimized for the SMD series body
• Compatible with K, M, P, and S workpiece material classifications

Compatibility

Designed as an OEM-style replaceable tip for SUMITOMO SMD series drill bodies requiring a 19.25mm diameter MEL-geometry tip with ACX80 grade carbide.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or tooling technician. Ensure the drill body is fully removed from the spindle or that the machine is in a safe, locked-out state before handling the replaceable tip. Use the manufacturer-specified torque wrench or assembly tool for tip seating — do not hand-tighten or use improvised tools. Verify through-coolant passages are clear and unobstructed before resuming cutting operations.
