Sumitomo 5KHY199 Carbide Replaceable Tip Drill 19.5mm Smd

Product Description

The SUMITOMO 5KHY199 is a carbide replaceable tip drill engineered for high-performance hole-making across a wide range of workpiece materials. Designed in the SMD series, it features a 19.5mm cutting diameter with a 140-degree included point angle and a 45-degree tip geometry. The solid carbide cutting tip carries a TiAlCr and TiSi PVD coating applied via physical vapor deposition, providing wear resistance and thermal stability during aggressive drilling cycles. Through-coolant capability delivers cutting fluid directly to the cutting edge, extending tool life and improving chip evacuation in deep-hole applications. This drill is intended for use by machining professionals in production and job-shop environments.

The 5KHY199 is suited for universal workpiece materials, including cast iron, steel, stainless steel, non-ferrous alloys, superalloys, and general-purpose materials — corresponding to ISO material codes H, K, M, N, P, and S. It fits standard SMD-series toolholders that accept the ACX70-grade replaceable tip interface. The through-coolant design makes it particularly effective in CNC machining centers where high-pressure coolant delivery is available. The replaceable tip design reduces cost per hole by allowing tip replacement without discarding the drill body.

Key Features

• Solid carbide cutting tip in SUMITOMO ACX70 grade with MTL insert geometry
• TiAlCr and TiSi PVD coating for wear resistance and thermal hardness
• 140-degree included point angle reduces thrust and improves centering
• Through-coolant design delivers fluid directly to the cutting zone
• Universal material compatibility across ISO codes H, K, M, N, P, and S
• Replaceable tip system minimizes tooling cost in high-volume drilling operations

Compatibility

Designed for use in SUMITOMO SMD-series drill bodies that accept ACX70-grade replaceable carbide tips at 19.5mm diameter. Confirm body series and tip seat geometry before ordering.

Installation Notes

Installation and setup should be performed by qualified machining personnel familiar with CNC tooling systems. Power down and lock out the spindle before seating or removing the replaceable tip. Follow the toolholder manufacturer's torque specifications for the tip-locking screw. Verify coolant channels are clear and unobstructed before resuming cutting operations.
