Seco 02694938 Square-shoulder End Mill 1-1/2 in 4 Flute

Product Description

The SECO 02694938 is an indexable square-shoulder end mill from the Power Turbo series, designed for high-efficiency milling operations in metalworking and machining environments. Built around ISO designation R217.69-01.50-0-184LAN, this tool features a 1.5 inches cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.669 inches. It accepts four XO.X 1806.. screw-held inserts and includes through-coolant capability to support extended run times and tighter thermal control during aggressive shoulder milling cuts. This tool is installed and used by machinists and tooling technicians working on CNC machining centers.

This end mill is suited for square-shoulder milling applications in both production and job-shop environments. The 90-degree lead angle produces true square shoulders in a single pass, making it appropriate for face milling, slotting, and step milling operations on ferrous and non-ferrous workpieces. The cylindrical shank interfaces with standard toolholders, and the through-coolant ports direct fluid directly to the cutting zone, improving chip evacuation and extending insert life during sustained cuts.
