Sumitomo 5KHZ225 Carbide Replaceable Tip Drill 14.5mm ACX80

Product Description

The SUMITOMO 5KHZ225 is a carbide replaceable tip drill from the SMD Series, designed for high-performance hole-making in a wide range of workpiece materials. It features a 14.5mm cutting diameter and a 140-degree included point angle with MEL insert geometry. The TiAlCr and TiSi PVD coating applied via physical vapor deposition provides heat resistance and extended tool life in demanding cutting conditions. Through-coolant capability delivers cutting fluid directly to the tip, reducing heat buildup and improving chip evacuation. This drill is specified for use by machinists and tool-and-die professionals in CNC turning and machining center applications.

The ACX80 grade and universal primary workpiece material classification make the 5KHZ225 suitable for cutting ferrous metals, stainless steels, cast iron, and superalloys, aligning with ISO material codes K, M, P, and S. It is well suited for production machining environments where consistent hole quality and tool change repeatability are critical. The replaceable tip design allows the carbide tip to be swapped at the machine without removing the drill body from the spindle, reducing downtime between tool changes.

Key Features

• 14.5mm cutting diameter with 140-degree included point angle for precise entry and reduced thrust force
• ACX80 solid carbide tip with TiAlCr and TiSi PVD coating for heat and wear resistance
• MEL insert geometry optimized for chip control across universal workpiece materials
• Through-coolant design directs fluid to the cutting zone for improved chip evacuation
• Replaceable tip construction allows fast tip changes without removing the drill body
• Compatible with ISO material groups K, M, P, and S for broad application coverage

Compatibility

Designed as an OEM-style replacement tip for use with SUMITOMO SMD Series replaceable tip drill bodies sized to accept a 14.5mm diameter tip with MEL geometry.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for replaceable tip drills. Ensure the spindle is fully stopped and the machine is in a safe state before changing the drill tip. Confirm the tip is properly seated and torqued to the drill body per the tool holder specification before resuming operation. Verify through-coolant supply pressure and flow rate are within the recommended range for the drilling application.
