Sumitomo U101367 Carbide Replaceable Tip Drill 7/8 in Smd

Product Description

The SUMITOMO U101367 is a carbide replaceable tip drill in the SMD series, designed for high-productivity hole-making in steel and similar ferrous workpiece materials. It features an ACX70 grade solid carbide tip with a TiAlCr and TiSi PVD coating applied through the MTL insert geometry. The 140-degree included point angle promotes stable entry and efficient chip formation. At 7/8 inch in diameter, this drill accepts through-coolant delivery to manage heat and evacuate chips at the cutting zone, extending tool life in demanding production environments. Licensed machinists and CNC operators working in job shop and production floor settings are the primary users.

This replaceable tip drill is intended for use in steel workpieces, classified under ISO material code P. The SMD series platform uses a modular design where the carbide tip indexes into a steel shank body, allowing tip replacement without removing the shank from the spindle. Typical applications include through-hole and blind-hole drilling in structural steel, carbon steel, and alloy steel components on CNC machining centers and turning centers equipped with through-spindle or through-tool coolant systems.

Key Features

• ACX70 grade solid carbide tip for wear resistance in steel cutting
• TiAlCr and TiSi PVD coating applied via MTL process for thermal and oxidation resistance
• 140-degree included point angle for stable, self-centering entry
• Through-coolant capability directs coolant directly to the cutting edge
• Replaceable tip design reduces tooling cost versus solid carbide drills
• 7/8 inch cutting diameter for common hole size requirements

Compatibility

Designed as an OEM-style replacement tip for SUMITOMO SMD series replaceable tip drill shank bodies accepting the MTL tip geometry at 7/8 inch diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the machine tool builder and toolholder manufacturer torque specifications for tip seating. Ensure the spindle is fully stopped and the machine is in an E-stop or lockout state before handling or indexing the carbide tip. Confirm through-coolant passages are clear and the tip is fully seated and secured before initiating a cut. Do not use damaged or improperly seated tips.
