Sumitomo 5KHY207 Replaceable Drill Tip 0.9055 in ACX70

Product Description

The SUMITOMO 5KHY207 is a replaceable drill tip designed for indexable drilling systems operating in steel cutting applications. Part of the SMD series, this solid carbide tip measures 0.9055 inches (23.00 mm) in cutting diameter and is manufactured to Grade ACX70 with a PVD-applied TiAlCr/TiSi dual-layer coating. The MTL insert geometry and 140-degree included angle provide controlled chip formation during deep-hole drilling operations. The tip features through-coolant capability, which supports heat management and chip evacuation in production environments. Machinists and CNC operators in metalworking shops are the primary installers of this tip type.

This replaceable drill tip is intended for use in steel workpieces classified under ISO material group P. The SMD series is engineered for modular drilling systems where the tip is exchanged independently of the drill body, reducing tooling cost per hole in high-volume production runs. Typical applications include drilling in carbon steel, alloy steel, and cast steel components on CNC machining centers and turning centers. The through-coolant design is especially effective in deep-hole drilling where conventional flood coolant cannot adequately reach the cutting zone.

Key Features

• Solid carbide construction in Grade ACX70 for wear resistance in steel cutting
• PVD-applied TiAlCr/TiSi dual-layer coating for thermal protection and extended tool life
• Through-coolant capability supports chip evacuation and cutting zone cooling
• MTL insert geometry with 140-degree included angle for controlled entry and chip formation
• Replaceable tip design compatible with SMD series modular drill bodies
• Optimized for ISO P material group (steel) primary workpiece material

Compatibility

Designed as a replaceable tip for SMD series modular indexable drill bodies. Verify body size compatibility with the 23.00 mm diameter specification before installation. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician following the drill body manufacturer's torque and seating procedures. Ensure the machine spindle is fully stopped and the tool is secured in a holder or vise before tip exchange. Inspect the tip pocket and seating surface for chips or debris prior to installation, as contamination can cause runout and premature tip failure. Verify coolant channel alignment with the drill body before returning the tool to service.
