Seco 02887523 Square-shoulder End Mill 1 in 3 Flute

Product Description

The SECO 02887523 is an indexable square-shoulder end mill designed for high-accuracy milling operations in metal-cutting environments. Built on the R217.94 cutter style platform and part of the Square T4-08 series, this tool accepts three LOEX inserts secured by screw clamping and delivers a maximum depth of cut of 8 mm (0.315 inches) at a 90-degree lead angle. The 1-inch cutting diameter and cylindrical shank make it compatible with standard milling machine spindles. Through-coolant capability helps manage heat and chip evacuation during aggressive cuts. The tool body is constructed from steel and reaches a maximum spindle speed of 16,500 RPM, making it suited for production milling work performed by machinists and tooling professionals.

This end mill is used in square-shoulder milling applications where a true 90-degree wall is required. It is appropriate for face milling, slotting, and step milling on steel, cast iron, and other machinable alloys in both production shop and job-shop settings. The three-insert configuration balances cutting performance with insert cost per edge. Through-coolant delivery is particularly useful in deep pocket and shoulder milling where flood coolant alone may not reach the cutting zone effectively.

Key Features

• 1-inch cutting diameter with 90-degree lead angle for true square-shoulder profiles
• Maximum depth of cut of 8 mm (0.315 inches) per pass
• Accepts 3 LOEX inserts held by screw clamping for secure, repeatable insert positioning
• Through-coolant design improves chip evacuation and thermal management at the cutting edge
• Maximum spindle speed of 16,500 RPM supports high-productivity milling cycles
• Steel tool body in the Square T4-08 series for rigidity and dimensional consistency

Compatibility

Designed for use with LOEX-style inserts. The ISO tool number R217.94-01.00-0-08-3A identifies this body within the SECO R217.94 cutter platform. Verify insert grade and geometry selection against SECO insert compatibility charts for the specific workpiece material.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the tool body. Confirm shank runout is within acceptable limits before beginning a cut, as excessive runout accelerates insert wear and reduces shoulder-wall accuracy. Follow the machine tool builder and insert manufacturer recommendations for feed rate, depth of cut, and coolant pressure when commissioning a new setup.
