Sumitomo U101378 Carbide Replaceable Tip Drill ACX70

Product Description

The SUMITOMO U101378 is a carbide replaceable tip drill from the SMD Series, designed for high-performance hole-making in steel and ferrous workpiece materials. The drill body accepts a solid carbide replaceable tip with MTL insert geometry and an ACX70 manufacturer grade, making it well suited for production drilling applications where tip replacement is preferred over full-tool replacement. The TiAlCr and TiSi PVD coating reduces friction and extends cutting life. The included point angle is 140 degrees, and the drill diameter is 1-1/32 inches. Through-coolant capability delivers cutting fluid directly to the cutting edge, improving chip evacuation and heat management at depth.

This replaceable tip drill is intended for use in machining centers and CNC lathes handling steel and similar P-category workpiece materials. The SMD Series platform is a common choice in production shops and job shops where consistent hole quality, repeatable tip indexing, and reduced tooling downtime are priorities. Licensed machinists and CNC operators in industrial machining environments are the primary installers and end users of this tool.

Key Features

• Solid carbide replaceable tip with ACX70 grade for extended tool life in steel
• TiAlCr and TiSi PVD dual coating reduces heat buildup and wear at the cutting edge
• 140-degree point angle suits general-purpose drilling in steel
• MTL insert geometry designed for steel and P-category workpiece materials
• Through-coolant design improves chip evacuation and cutting performance at depth
• SMD Series platform allows tip replacement without discarding the drill body

Compatibility

Designed as an OEM-style replaceable tip drill within the SUMITOMO SMD Series platform for steel and ferrous P-category workpiece materials.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's tool-change procedure. Ensure the spindle is fully stopped and the machine is in a safe state before accessing or replacing the drill tip. Verify that the coolant-through passages in the tool holder and spindle are clear and properly connected before running through-coolant operations. Follow shop safety protocols and applicable OSHA machine guarding requirements when handling carbide cutting tools.
