Sumitomo 5KHZW14 Carbide Replaceable Tip Drill ACX80

Product Description

The SUMITOMO 5KHZW14 is a carbide replaceable tip drill designed for high-performance metal cutting applications. Built to the SMD series standard, it features a 1.0313 inch (26.20 mm) cutting diameter and a 140-degree included angle. The tip is manufactured from solid carbide with an ACX80 grade designation and a PVD-applied TiAlCr and TiSi dual-layer coating. Through-coolant capability allows direct coolant delivery to the cutting edge, supporting chip evacuation and thermal management during deep or high-feed drilling operations. This drill is handled by machinists and tool-room technicians in production and job-shop environments.

The 5KHZW14 is suited for drilling into a range of workpiece materials, including cast iron and hardened materials (K code), stainless and heat-resistant steels (M code), carbon and alloy steels (P code), and superalloys and titanium (S code). The MEL insert geometry is matched to these material groups for balanced cutting action and edge stability. Typical applications include structural component drilling, fixture work, and production runs where consistent hole quality and tool life are priorities.

Key Features

• Solid carbide ACX80-grade replaceable tip for consistent wear resistance
• TiAlCr and TiSi PVD coating for thermal protection and reduced built-up edge
• Through-coolant design supports chip flushing and heat control at the cutting zone
• 140-degree included angle suits a broad range of steel and superalloy workpieces
• MEL insert geometry engineered for multi-material compatibility across K, M, P, and S codes
• SMD series platform allows tip replacement without discarding the drill body

Compatibility

Designed as an OEM-style replaceable tip for use in the SMD series drill body system. Compatible workpiece material codes include K, M, P, and S classifications per ISO turning and drilling material group standards.

Installation Notes

Replaceable tip drills of this type are installed and serviced by machinists or CNC tooling technicians. Before tip replacement, the machine spindle must be fully de-energized and the tool secured in a vise or tool holder to prevent movement. Follow the drill body manufacturer torque and seating procedure for the specific SMD body being used. Through-coolant fittings should be inspected at each tip change to confirm clean, unobstructed coolant flow.
