Sumitomo 5KHY196 Carbide Replaceable Tip Drill 18mm Smd

Product Description

The SUMITOMO 5KHY196 is a carbide replaceable tip drill designed for high-performance metal cutting in demanding production environments. Built to the SMDT1800MTL specification within the SMD Series, this drill features an 18mm cutting diameter and a 140-degree included point angle suited for clean entry and reduced thrust in steel applications. The insert geometry is MTL, the grade is ACX70, and the cutting tip is solid carbide with a PVD-applied TiAlCr and TiSi dual-layer coating for heat resistance and extended tool life. Through-coolant capability delivers cutting fluid directly to the cutting edge, supporting chip evacuation and thermal control at elevated feed rates.

This replaceable tip drill is engineered for primary use in steel workpiece materials (ISO material code P). It is well suited for CNC machining centers and turning centers where through-spindle coolant is available. The replaceable tip design reduces tooling cost compared to solid indexable drills by allowing tip replacement without discarding the full drill body. Typical applications include hole-making in carbon steel, alloy steel, and similar ferrous materials in aerospace, automotive, die-and-mold, and general precision machining environments.

Key Features

• Solid carbide replaceable tip construction in ACX70 grade for wear resistance in steel cutting
• PVD-applied TiAlCr and TiSi dual-layer coating for thermal stability and reduced built-up edge
• 140-degree included point angle for reduced thrust and clean entry
• Through-coolant design directs fluid to the cutting zone for chip flushing and temperature control
• MTL insert geometry optimized for steel (ISO P) workpiece materials
• SMD Series platform supports interchangeable tips across compatible drill body sizes

Compatibility

Designed as a replaceable tip for SUMITOMO SMD Series drill bodies accepting the SMDT1800MTL tip configuration at 18mm diameter. Confirm body series and tip seat geometry before ordering to ensure proper seating and runout.

Installation Notes

Installation of replaceable tip drills should be performed by qualified machinists following the tool manufacturer's seating and torque procedures for the SMD Series body. Ensure the drill body tip seat is clean and free of chips or debris before seating the tip. Verify through-coolant passages are clear and that spindle coolant pressure meets the requirements of the machining application before running. Do not exceed the drill body manufacturer's recommended speed and feed parameters for the ACX70 grade in the target workpiece material.
