Sumitomo U103822 Carbide Replaceable Tip Drill 7/8 in ACX70

Product Description

The SUMITOMO U103822 is a carbide replaceable tip drill from the SMD Series, designed for high-performance hole-making in metal fabrication and machining applications. The tip is manufactured from solid carbide in the ACX70 grade and features a dual-layer TiAlCr and TiSi coating applied via PVD process. The 140-degree included point angle suits drilling into flat and curved surfaces with reduced walking. Through-coolant capability supports higher feed rates and extended tool life by delivering coolant directly to the cutting edge. This drill is a replacement tip intended for compatible SMD Series holders and is installed by machinists and tooling technicians in production and job-shop environments.

The U103822 is suited for drilling cast iron and steel workpieces, corresponding to ISO material codes K and P. The MTL-C insert geometry is optimized for stable chip formation in these ferrous materials. This tip is typically used in CNC machining centers and drill presses where replaceable-tip systems reduce downtime by allowing quick tip swaps without removing the full drill body from the spindle. It fits into the SMD Series modular drill platform.

Key Features

• Solid carbide ACX70 grade tip for hardness and wear resistance in ferrous materials
• TiAlCr and TiSi PVD coating for thermal protection and reduced built-up edge
• 140-degree point angle for self-centering entry on flat and irregular surfaces
• Through-coolant design delivers fluid directly to the cutting zone
• MTL-C insert geometry optimized for cast iron and steel chip control
• Replaceable tip format minimizes holder changes and reduces tooling downtime

Compatibility

Designed for use with compatible SUMITOMO SMD Series modular drill holders. Intended for machining cast iron and steel workpieces, ISO material codes K and P.

Installation Notes

Replaceable tip drills are installed and serviced by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before removing or seating the tip. Clean the tip pocket on the holder before installation to ensure proper seating and runout. Follow the holder manufacturer's torque and engagement specifications for the SMD Series interface.
