Sumitomo 5KHY200 Carbide Replaceable Tip Drill 20mm ACX70

Product Description

The SUMITOMO 5KHY200 is a carbide replaceable tip drill designed for high-performance hole-making in steel and ferrous workpiece materials. Built to the SMD series standard, this drill features a 20mm diameter cutting tip manufactured from solid carbide in the ACX70 grade. The tip geometry follows the MTL insert profile with a 140-degree point angle, delivering consistent chip control and entry stability. A dual-layer TiAlCr and TiSi coating applied via PVD process provides thermal resistance and wear life suited to production machining environments. Through-coolant capability supports chip evacuation and tool life in deeper hole applications.

This replaceable tip drill is intended for metalcutting operations where the primary workpiece material is steel, classified under ISO material group P. The SMD series design separates the carbide tip from the steel shank body, allowing tip replacement without changing the full drill assembly. Typical applications include CNC machining centers performing drilling operations in automotive, die and mold, and general precision manufacturing environments. Licensed machinists and CNC tooling specialists are the primary end users for this product.

Key Features

• Solid carbide tip in ACX70 manufacturer grade for extended wear resistance in steel machining
• TiAlCr and TiSi dual-layer PVD coating for high-temperature and oxidation resistance
• 140-degree included point angle with MTL geometry for stable entry and reduced thrust force
• Through-coolant design supports chip evacuation and consistent tool life in production drilling
• Replaceable tip construction reduces tooling cost by retaining the steel shank body across tip changes
• SMD series platform with ISO P material code rating for steel workpiece applications

Compatibility

Designed as a replaceable tip for use with compatible SUMITOMO SMD series drill shank bodies accepting a 20mm tip diameter. Confirm shank body model compatibility with the SMD series tip interface before ordering.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or tooling technician following the machine tool manufacturer and toolholder torque interface procedures. Ensure the spindle is fully stopped and the machine is in a safe state before accessing the drill body. Inspect the shank seat and clamping interface for chips or debris before seating the replacement tip. Do not force the tip into the pocket; proper seating is critical to runout and performance.
