Sumitomo U101402 Carbide Replaceable Tip Drill 20.5mm

Product Description

The SUMITOMO U101402 is a carbide replaceable tip drill in the SMD series, designed for high-efficiency hole-making in cast iron and steel workpieces. The drill body accepts the SMDT2050MTL-C tip, which is manufactured from solid carbide and coated with a dual-layer TiAlCr and TiSi finish applied via PVD process. The cutting diameter is 20.5mm (0.8071 inches), and the tip geometry features a 140-degree included angle for stable entry and reduced thrust force. Through-coolant capability supports chip evacuation and tool life in production drilling environments. This tool is installed and used by machinists and tool-and-die professionals in metalworking and manufacturing operations.

The U101402 is suited for drilling cast iron and steel in both horizontal and vertical machining center applications. The MTL-C insert geometry is optimized for these material groups, corresponding to ISO material codes K (cast iron) and P (steel). The replaceable tip design allows the carbide insert to be swapped out without replacing the drill body, reducing tooling cost per hole in production runs. This makes it a practical choice for job shops and production floors running medium-to-large diameter drilling cycles.

Key Features

• Solid carbide replaceable tip in the SMD series with MTL-C geometry
• Cutting diameter: 20.5mm (0.8071 inches)
• 140-degree included angle for stable, low-thrust entry
• Dual TiAlCr and TiSi PVD coating for wear resistance in cast iron and steel
• Through-coolant design supports chip evacuation and extended tip life
• ACX70 grade carbide substrate matched to ferrous workpiece materials

Compatibility

Designed for use with SMD series drill bodies accepting the SMDT2050MTL-C replaceable tip. Intended for machining cast iron (ISO K) and steel (ISO P) workpiece materials.

Installation Notes

Replaceable tip drills should be installed and torqued according to the toolholder manufacturer specifications using the correct tip wrench for the SMD series. Ensure the drill body is clean and free of chips or debris before seating the carbide tip. Verify through-coolant connections are properly sealed before running at pressure. Tip replacement and setup should be performed by a qualified machinist with the machine in a locked-out, de-energized state.
