Sumitomo 5KHY212 Replaceable Drill Tip 25mm Solid Carbide

Product Description

The SUMITOMO 5KHY212 is a replaceable drill tip designed for use in the SMD modular drill system. Manufactured from solid carbide with a PVD-applied TiAlCr and TiSi multilayer coating, this tip delivers consistent cutting performance in steel and other P-category workpiece materials. It features a 25.00 mm (0.9843 inch) cutting diameter, an MTL insert geometry, and through-coolant capability to manage heat and chip evacuation at the cutting zone. The ACX70 grade is engineered for demanding drilling applications where edge retention and thermal resistance are priorities. Licensed machinists and CNC operators are the primary users of this tip.

The 5KHY212 is suited for production drilling in steel workpieces, classified under ISO material group P. The SMD series is a modular drill platform where the carbide tip is separately replaceable from the steel drill body, reducing tooling cost per hole while maintaining consistent geometry. Through-coolant delivery supports higher feed rates and longer tool life in deep-hole and interrupted-cut scenarios. This tip is appropriate for CNC machining centers and turning centers equipped with coolant-through toolholders.

Key Features

• Solid carbide construction in ACX70 grade for wear resistance in steel cutting
• TiAlCr and TiSi PVD coating for thermal stability and reduced built-up edge
• Through-coolant compatible for effective chip evacuation and heat management
• MTL insert geometry with a 140-degree included angle for controlled entry and centering
• 25.00 mm (0.9843 inch) cutting diameter in the SMD replaceable-tip drill series
• Sold individually, compatible with SMD series modular drill bodies

Compatibility

Designed for use with SUMITOMO SMD series modular drill bodies that accept replaceable carbide tips at the 25.00 mm cutting diameter. Confirm body series and interface compatibility before ordering.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or tooling technician with the machine spindle locked and all power isolated. Use the manufacturer-specified tip wrench or torque tool for the SMD interface; do not substitute improvised tools that may damage the seating surfaces. Inspect the drill body pocket and coolant ports for debris or damage before seating the new tip. Follow your facility safety procedures and applicable OSHA machine-guarding standards during tip changes.
