Sumitomo 5KHZW12 Carbide Replaceable Tip Drill ACX80 Smd

Product Description

The SUMITOMO 5KHZW12 is a carbide replaceable tip drill designed for high-performance hole-making in a wide range of workpiece materials. Built to the SMD series standard, this drill features a solid carbide tip with a TiAlCr and TiSi PVD coating applied through a physical vapor deposition process for extended tool life and heat resistance. The included angle measures 140 degrees with an MEL insert geometry, optimized for chip control and point stability at entry. Through-coolant capability directs cutting fluid directly to the cutting edge, supporting deeper hole applications and chip evacuation. The drill body accepts replaceable tips, reducing tooling cost by allowing tip exchange without scrapping the full shank.

The 5KHZW12 is suited for machining centers and CNC drilling operations where universal material capability is required. The ACX80 grade and dual-layer TiAlCr and TiSi coating make it applicable across steel, stainless steel, cast iron, and superalloys, corresponding to ISO material groups P, M, K, and S. Typical install scenarios include production drilling in job shops, aerospace component machining, and general metalworking environments where consistent hole quality and insert interchangeability are priorities.

Key Features

• Solid carbide replaceable tip construction reduces per-hole tooling cost
• TiAlCr and TiSi PVD dual coating for elevated heat and wear resistance
• 140-degree included angle with MEL geometry for stable entry and controlled chip formation
• Through-coolant design supports chip evacuation and thermal management in deep-hole drilling
• ACX80 grade rated for universal material groups P, M, K, and S
• SMD series body accepts standard SMD replaceable tips for fast changeover

Compatibility

Designed as an OEM-style replacement tip drill body within the Sumitomo SMD series, accepting SMD-compatible replaceable carbide tips. Specific compatible tip part numbers were not provided in available product data.

Installation Notes

Installation and tip exchange should be performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and the tool holder de-energized before any tip replacement or body mounting. Use the appropriate torque wrench and tip-locking hardware specified by the toolholder manufacturer. Through-coolant connections must be confirmed leak-free and at the correct supply pressure before running the first hole.
