Seco 02694936 Indexable Square-shoulder End Mill

Product Description

The SECO 02694936 is an indexable square-shoulder end mill designed for precision milling operations in metal cutting applications. Built on the Power Turbo series platform, it features a 1-1/4 inch cutting diameter and a 90-degree lead angle, producing true square shoulders on workpiece profiles. The tool runs a cylindrical shank with a 1-inch shank diameter and accepts XO.X 1806.. style inserts secured by screw clamping. With through-coolant capability and a maximum rated speed of 11,100 RPM, it is suited for high-performance roughing and finishing passes. Machinists and tool room professionals install this holder in CNC machining centers and manual milling setups requiring consistent shoulder geometry.

This end mill is appropriate for general milling operations where a 90-degree square shoulder is required. The R217.69-18A cutter style designation identifies it within the SECO Power Turbo toolholder family. It is used in production and job shop environments on vertical and horizontal machining centers. The 3-insert, 3-flute configuration supports stable cutting at the rated spindle speeds. Through-coolant delivery helps manage chip evacuation and heat at the cutting zone, which is critical when running at elevated feed rates in steel, cast iron, and similar materials.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and machine in a locked-out, tagged-out state per applicable shop safety procedures. Verify that the toolholder shank seats fully and is clamped to the machine specification for the collet or chuck style in use. Insert seating surfaces should be clean and free of chips before indexing or replacing inserts. Through-coolant connections should be confirmed leak-free before initiating a cutting cycle.
