Sumitomo 5KHZW07 Carbide Replaceable Tip Drill 9/16 in ACX80

Product Description

The SUMITOMO 5KHZW07 is a carbide replaceable tip drill designed for high-performance hole-making across a wide range of workpiece materials. Built to the SMD series standard, this drill body accepts an MEL insert geometry tip manufactured from solid carbide with an ACX80 grade. The DEX PVD coating delivers surface hardness and heat resistance suited to demanding production environments. The 140-degree included angle geometry provides a self-centering entry and reduces thrust force on entry. Internal through-coolant passages direct cutting fluid directly to the cutting edge, supporting chip evacuation and tool life in both interrupted and continuous cuts.

The 5KHZW07 is a replacement tip component for use in SMD series drill bodies sized for a 9/16-inch diameter. It is applicable to universal workpiece material categories covering cast iron, stainless steel, carbon and alloy steel, and superalloys, corresponding to ISO material codes K, M, P, and S. This part is suited for CNC machining centers in production shops, job shops, and tool-and-die operations where repeatable hole quality and reduced tooling downtime are priorities. A licensed machinist or tooling specialist typically selects and installs this tip.

Key Features

• Solid carbide tip in ACX80 manufacturer grade for wear resistance in multi-material applications
• DEX PVD coating applied via physical vapor deposition for extended cutting edge life
• MEL insert geometry engineered for stable, self-centering drill entry
• 140-degree included point angle reduces thrust and improves centering on flat and curved surfaces
• Through-coolant design channels fluid to the cutting zone for chip control and thermal management
• SMD series replaceable tip design allows tip swap without removing the drill body from the machine

Compatibility

Designed as a replaceable tip for SUMITOMO SMD series drill bodies in the 9/16-inch diameter range. Compatible with ISO workpiece material groups K, M, P, and S as specified by the manufacturer.

Installation Notes

Installation of replaceable carbide drill tips should be performed by a qualified machinist with the machine spindle fully stopped and locked out. Use the manufacturer-specified torque driver or wrench for the SMD series tip seat to avoid cracking the carbide tip or damaging the seating surface. Inspect the drill body seat for chips, debris, or wear before installing a new tip. Do not use the drill without confirming the tip is fully seated and secured per the tooling documentation.
