Sumitomo U101357 Carbide Replaceable Tip Drill 49/64 in

Product Description

The SUMITOMO U101357 is a carbide replaceable tip drill from the SMD Series, designed for high-performance hole-making in steel and other ferrous workpiece materials. The drill features a 49/64-inch diameter, a 140-degree included point angle, and a TiAlCr/TiSi PVD coating applied to an ACX70-grade solid carbide tip with MTL insert geometry. Through-coolant capability channels cutting fluid directly to the cutting edge, reducing heat buildup and extending tool life in demanding production environments. This drill is installed and operated by machining professionals in CNC turning and machining center applications.

The U101357 is suited for production drilling in steel and ferrous materials where consistent hole quality and tool life are priorities. The replaceable tip design allows the carbide insert to be swapped out at the machine without removing the drill body, minimizing downtime in high-volume operations. The SMD Series platform is commonly found in horizontal and vertical machining centers running moderate to high feed rates in P-category workpiece materials.

Key Features

• ACX70-grade solid carbide tip for wear resistance in steel machining
• TiAlCr/TiSi PVD coating applied via physical vapor deposition for thermal and oxidation resistance
• 140-degree included point angle suited for general-purpose and steel drilling
• Through-coolant design delivers coolant directly to the cutting zone
• MTL insert geometry optimized for steel (P-category) workpiece materials
• Replaceable tip construction reduces tooling cost compared to solid-body drills

Compatibility

Designed as a replaceable tip insert for the SUMITOMO SMD Series drill body system. Compatible with SMD Series bodies accepting the MTL insert geometry in the corresponding 49/64-inch diameter size.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The drill body must be fully de-energized and the machine spindle locked before seating or removing the replaceable tip. Use the manufacturer-specified torque wrench and clamping screw to secure the carbide tip — do not overtighten by hand or use unapproved tools, as this can crack the carbide insert or damage the seating pocket. Verify coolant passage alignment and flow rate before returning the tool to production.
