Sumitomo U101339 Carbide Replaceable Tip Drill 19/32 in ACX70

Product Description

The SUMITOMO U101339 is a carbide replaceable tip drill designed for high-performance hole-making in steel workpieces. Part of the SMD Series, this drill features a solid carbide tip with MTL insert geometry and a dual-layer TiAlCr/TiSi coating that resists heat and wear during cutting operations. The 140-degree included point angle promotes accurate entry and efficient chip evacuation. Through-coolant capability directs cutting fluid directly to the cutting edge, extending tool life and improving chip control in deep-hole applications. Weighing 0.023 pounds, this is a lightweight, precision-ground tool installed by machinists and tool-and-die professionals in production drilling environments.

This replaceable tip drill is suited for drilling steel in CNC machining centers and turning centers where consistent hole geometry and tool longevity are required. The ACX70 carbide grade is matched to P-category workpiece materials, which covers a broad range of carbon, alloy, and tool steels commonly encountered in production machining. The replaceable tip design reduces tooling cost by allowing tip replacement without discarding the drill body. It is appropriate for both roughing and finish-drilling passes where dimensional accuracy and surface finish at the bore are critical to part acceptance.

Key Features

• Solid carbide tip with ACX70 grade optimized for steel (P-category) workpiece materials
• TiAlCr/TiSi dual-layer coating for heat resistance and extended wear life
• 140-degree included point angle for accurate drill entry and reduced thrust force
• Through-coolant design delivers fluid directly to the cutting zone
• MTL insert geometry in the SMD Series for replaceable tip convenience
• 19/32 inch diameter nominal cutting size

Compatibility

Designed as an OEM-style replaceable tip for use with compatible SMD Series drill bodies accepting the MTL insert geometry in the 19/32 inch diameter range. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation of replaceable carbide drill tips should be performed by a qualified machinist or tooling technician. Ensure the drill body is fully de-energized and the machine spindle is locked before seating or removing the tip. Use the manufacturer-specified torque tool and follow the SMD Series assembly procedure to avoid tip unseating or body damage during operation. Inspect the drill body interface for wear or debris before each tip change.
