Seco 02694949 Indexable Square-shoulder End Mill 1-1/4in

Product Description

The SECO 02694949 is an indexable square-shoulder end mill engineered for demanding milling applications in metal-cutting environments. Built to the R217.69-18A toolholder cutter style, it accepts XO.X 1806.. series inserts secured by screw-clamp retention. The tool features a 1-1/4 inch cutting diameter, a maximum depth of cut of 0.669 inches, and a 90-degree lead angle for true square-shoulder profiling. With through-coolant capability and a maximum spindle speed of 11,100 RPM, it is suited for high-productivity roughing and finishing passes. Licensed machinists and CNC setup technicians are the primary users of this tool.

This end mill fits into the SECO Power Turbo series product family and is intended for CNC milling centers handling steel, cast iron, and similar workpiece materials where square-shoulder engagement and chip-load consistency are critical. The Weldon flat shank provides positive rotational drive in milling chucks and Weldon-style holders. With three cutter positions and a usable length of 3.189 inches, it is well suited to side-milling, slotting, and shoulder-milling operations on production equipment. ISO designation R217.69-01.25-3-18-3AN identifies this tool in SECO catalog systems.

Key Features

• Accepts XO.X 1806.. indexable inserts retained by screw clamp for fast changeover
• Through-coolant design channels fluid directly to the cutting edge for heat control and chip evacuation
• Weldon flat shank eliminates slip under high torque drive conditions
• 3-insert cutter body supports balanced chip load across all flutes
• Maximum spindle speed of 11,100 RPM supports high-feed milling strategies

Compatibility

Compatible with R217.69-18A toolholders and XO.X 1806.. insert style. ISO designation R217.69-01.25-3-18-3AN. Designed for use in CNC milling machines equipped with through-spindle coolant and Weldon-style tool holding systems.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Secure the Weldon flat shank firmly in a matching Weldon-style holder and verify insert seating and screw torque before spindle operation. Confirm through-coolant passages are clear and pressure is set to the machine specification before starting a cut. Inspect insert edges for wear or chipping at regular intervals and index or replace inserts before continued production use.
