Sumitomo 5KHZW0N Replaceable Drill Tip 0.7969 in ACX80

Product Description

The SUMITOMO 5KHZW0N is a replaceable drill tip engineered for the SMD modular drill system. It features a 0.7969 inch cutting diameter and is manufactured from solid carbide with an ACX80 grade designation. The tip carries a PVD-applied TiAlCr and TiSi dual coating for extended wear resistance and thermal stability at the cutting edge. A through-coolant design channels fluid directly to the cutting zone, reducing heat buildup and evacuating chips efficiently. This tip is installed by machinists and toolroom technicians working in precision drilling applications on CNC machining centers.

The 5KHZW0N is suited for universal workpiece materials and carries a primary workpiece material classification of K, M, P, and S, covering cast iron, stainless steel, steel, and high-temperature alloys. The MEL insert geometry and 140 degree included angle make this tip effective across a broad range of drilling scenarios in both production and job-shop environments. It is sold individually and designed for quick tip exchange without removing the tool body from the spindle.

Key Features

• Solid carbide construction in ACX80 grade for hardness and thermal resistance
• PVD-applied TiAlCr and TiSi dual coating extends tool life in demanding materials
• Through-coolant design directs fluid to the cutting edge for chip evacuation and heat control
• 140 degree included angle with MEL geometry supports stable entry and accurate hole positioning
• Replaceable tip format reduces tooling cost by allowing tip exchange on a retained body
• Universal material classification covers cast iron, steel, stainless, and high-temperature alloys

Compatibility

Designed for use with the Sumitomo SMD series modular drill body system. Verify body bore diameter and series compatibility before installation.

Installation Notes

This replaceable drill tip is installed and serviced by machinists or toolroom technicians on CNC machining centers. Power down and lock out the spindle before removing or seating the tip. Use the manufacturer-specified torque wrench and seating procedure for SMD-series tips to ensure proper clamping and runout. Do not exceed the recommended cutting parameters for the grade and coating specified on the tool body.
