Sumitomo U101354 Carbide Replaceable Tip Drill ACX70

Product Description

The SUMITOMO U101354 is a carbide replaceable tip drill from the SMD series, designed for high-productivity hole-making in steel workpieces. The tip is manufactured from solid carbide with a TiAlCr/TiSi coating applied via PVD process, delivering thermal resistance and extended edge life under demanding cutting conditions. The drill features a 140-degree included point angle and a 23/32-inch diameter, making it suited for precision drilling operations where dimensional accuracy and tool longevity are priorities. Through-coolant capability allows cutting fluid to be delivered directly to the cutting edge, reducing heat buildup and evacuating chips effectively during deep-hole or high-feed applications. Licensed machinists and CNC machine operators are the primary end users.

This replaceable tip drill is engineered for use in steel-cutting applications, classified under workpiece material code P, which covers carbon steels, alloy steels, and similar ferrous materials. The SMD series platform uses a tip-exchange design, allowing worn inserts to be swapped without replacing the full drill body. This geometry and coating combination is appropriate for CNC machining centers and turning centers equipped with through-spindle coolant. The MTL insert geometry is optimized for stable cutting action in P-group materials, making this drill a practical choice for production environments focused on reducing cycle time and tooling cost.

Key Features

• Solid carbide tip construction with TiAlCr/TiSi PVD coating for heat and wear resistance
• 140-degree included point angle for accurate entry and reduced thrust in steel
• Through-coolant design delivers coolant directly to the cutting zone for chip evacuation and thermal control
• Replaceable tip platform reduces tooling cost by allowing body reuse
• ACX70 manufacturer grade optimized for P-group steel workpiece materials
• MTL insert geometry engineered for stable, consistent performance in ferrous materials

Compatibility

Designed as a replaceable tip insert for SUMITOMO SMD series drill bodies accepting the MTL geometry in the 23/32-inch diameter size. Confirm body series and seat designation against SUMITOMO SMD series tooling documentation before ordering.

Installation Notes

Installation and tip exchange should be performed by a qualified machinist or tooling technician following the machine tool manufacturer lockout/tagout procedures before handling tooling. Use the appropriate torque wrench and Sumitomo-specified seat screws when seating the carbide tip to ensure proper clamping without over-torquing. Inspect the drill body seat for chips, damage, or debris before mounting the replacement tip, as contamination on the seating surface will affect runout and drill life. Ensure through-coolant pressure and flow rate meet the machine and tooling specifications before initiating a cut.
