Sumitomo U101330 Carbide Replaceable Tip Drill ACX70

Product Description

The SUMITOMO U101330 is a carbide replaceable tip drill in the SMD series, designed for high-performance hole-making in steel workpieces. It features a solid carbide tip with a 140-degree included point angle and a TiAlCr/TiSi coating applied via PVD process. The MTL insert geometry and ACX70 grade make this drill well suited for demanding ferrous material applications. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, extending tool life and improving chip evacuation in deep-hole operations. This drill is installed and used by machinists and tooling technicians in production and job-shop environments.

This replaceable tip drill is intended for use on steel (ISO material code P) in CNC machining centers and similar setups where through-coolant is available. The replaceable tip design allows the carbide tip to be swapped out without replacing the entire drill body, reducing tooling cost per hole over the life of the holder. It is suited for applications requiring consistent hole quality in medium to high-volume production runs on steel components.

Key Features

• Solid carbide ACX70 grade tip engineered for steel cutting (ISO P workpiece material)
• 140-degree point angle for reduced thrust and improved centering on entry
• TiAlCr/TiSi dual-layer PVD coating for heat resistance and extended tool life
• Through-coolant design delivers fluid directly to the cutting edge for chip evacuation and thermal management
• MTL insert geometry optimized for steel applications
• Replaceable tip construction reduces overall tooling cost versus solid drill replacement

Compatibility

Designed for use with compatible SUMITOMO SMD series drill bodies that accept replaceable carbide tips. Confirm body size and tip interface compatibility with the specific SMD holder before ordering.

Installation Notes

Installation of the replaceable tip should be performed by a qualified machinist or tooling technician using the appropriate torque tool specified by the drill body manufacturer for the SMD series interface. Ensure the machine spindle is fully stopped and locked out before tip removal or installation. Inspect the tip seat and body threads for damage or contamination before seating the new tip. Verify through-coolant passages are clear before resuming machining operations.
