Sumitomo 5KHY214 Carbide Replaceable Tip Drill 26mm ACX70

Product Description

The SUMITOMO 5KHY214 is a carbide replaceable tip drill in the SMD series, designed for high-performance drilling in steel and steel alloy workpieces. The drill features a 26mm diameter cutting tip with a 140-degree included point angle, making it suitable for precise, stable entry and through-hole drilling operations. The tip is manufactured from solid carbide with an ACX70 grade designation and a PVD-applied TiAlCr and TiSi coating, which provides thermal resistance and extended tool life in ferrous materials. Through-coolant capability is integrated into the body, allowing pressurized coolant delivery directly to the cutting edge during operation. This part is installed by machinists and tooling technicians in CNC drilling and machining center applications.

The 5KHY214 is used in production machining environments where replaceable tip drills are preferred for cost efficiency and consistent hole quality. It is suited for primary use in steel workpieces, classified under ISO material group P. The through-coolant design supports chip evacuation and edge cooling during deep or high-feed drilling cycles. Typical applications include job shops, aerospace component manufacturing, and general metalworking operations using horizontal or vertical CNC machining centers.

Key Features

• Solid carbide tip with ACX70 manufacturer grade for durability in steel applications
• TiAlCr and TiSi PVD coating for thermal resistance and extended cutting life
• 26mm cutting diameter with 140-degree included point angle for stable entry
• Through-coolant design delivers pressurized coolant directly to the cutting zone
• MTL insert geometry optimized for steel and ferrous workpiece materials
• Replaceable tip design reduces tooling cost compared to solid drill replacement

Compatibility

Designed as an OEM-style replacement tip for SMD series replaceable tip drill bodies requiring a 26mm ACX70-grade carbide tip with through-coolant capability.

Installation Notes

Installation of replaceable tip drills should be performed by qualified tooling technicians following the machine tool manufacturer and drill body manufacturer guidelines. Ensure the spindle and tool holder are fully powered down and locked out before tip removal or installation. Use the correct torque tool and seating procedure specified by the drill body manufacturer to avoid tip runout or premature failure. Verify through-coolant passages are clear and that the machine coolant pressure is within the acceptable range for the tool body before resuming operation.
