Sumitomo U101336 Carbide Replaceable Tip Drill 9/16 in ACX70

Product Description

The SUMITOMO U101336 is a carbide replaceable tip drill designed for high-performance hole-making in metalworking applications. Built on the SMD series platform, this drill uses a solid carbide tip with the SMDT05625MTL-C insert geometry and an ACX70 manufacturer grade. The cutting diameter measures 0.5625 inches (9/16 inches), and the included angle is 140 degrees. A TiAlCr and TiSi coating applied via PVD process provides wear resistance and thermal stability during cutting. Through-coolant capability keeps the cutting zone clear and extends tip life during deep or high-feed operations. Licensed machinists and CNC operators are the primary users for this tooling.

This drill is suited for production drilling in cast iron and steel workpieces, corresponding to material codes K and P. The replaceable tip design allows the carbide insert to be swapped out without replacing the full drill body, reducing tooling cost per hole in repetitive operations. Typical applications include job shops, production machining cells, and maintenance facilities working with ferrous materials where consistent hole diameter and finish are required.

Key Features

• Solid carbide tip with ACX70 grade for durability in ferrous materials
• TiAlCr and TiSi PVD coating for thermal and wear resistance
• 140-degree included angle optimized for steel and cast iron entry
• Through-coolant design for chip evacuation and extended tool life
• MTL-C insert geometry for controlled cutting action
• Replaceable tip system reduces per-hole tooling cost versus solid drills

Compatibility

Designed for use with SMD series drill bodies accepting the SMDT05625MTL-C replaceable carbide tip. Compatible with cast iron and steel workpieces (material codes K and P).

Installation Notes

Installation of the replaceable tip should be performed with the spindle fully stopped and machine power locked out per shop safety procedures. Use the manufacturer-recommended torque tool for seating the carbide tip to ensure proper clamping without over-torquing the insert seat. Verify through-coolant passages are clear and coolant pressure is appropriate for the application before initiating a cut. This tooling is intended for use by qualified machinists familiar with CNC or manual drilling operations.
