Sumitomo 14EK728 Milling Insert DL1000 Solid Carbide Seet

Product Description

The SUMITOMO 14EK728 is a solid carbide milling insert designed for high-performance material removal in precision machining applications. Manufactured to the SEET insert style in a square shape with size code 13T3, this insert measures 0.528 inches in inscribed circle diameter and 0.156 inches thick. It carries the DL1000 manufacturer grade and features a diamond-like carbon (DLC) coating process, providing enhanced surface hardness and lubricity. The chip breaker designation is L, suited for controlled chip formation. Machinists and CNC operators working in metalworking shops and production environments will find this insert appropriate for finishing and semi-finishing passes.

This insert is engineered primarily for non-ferrous metal workpiece materials, indicated by the primary workpiece material code N. Typical applications include milling aluminum, copper, brass, and similar non-ferrous alloys where a DLC-coated solid carbide edge delivers clean cuts with reduced built-up edge. The insert is sold individually per package with a minimum order quantity of 10 units, making it suited for production tooling replenishment programs where consistent insert grades are required across multiple tool bodies.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert screw specified by the tool body manufacturer when seating the insert. Inspect the tool body pocket for debris or damage before installing a new insert.
