Seco 02553730 Indexable High-feed End Mill 1-1/4 in

Product Description

The SECO 02553730 is an indexable high-feed end mill designed for aggressive material removal in milling operations. It accepts two 218.19-160 inserts held by screw-lock retention and delivers a maximum depth of cut of 0.08 inches at speeds up to 19,700 RPM. The 1.25-inch cylindrical shank seats into Toolholder Style R217.21, and through-coolant capability keeps the cutting zone clear during high-feed passes. At 7.5 inches overall length, the tool offers sufficient reach for a wide range of milling setups. Licensed machinists and CNC operators are the primary users of this tool in production and job-shop environments.

This end mill is built for high-feed milling applications where maximizing metal removal rate is the priority. The 2-flute design with a 1.25-inch maximum cutting diameter and a 0.6-inch minimum cutting diameter supports both full-width and partial-engagement passes. A maximum ramping angle of 1.50 degrees allows controlled helical or ramp entry into the workpiece, reducing shock loading on the inserts. Through-coolant delivery extends insert life and improves chip evacuation during continuous cutting cycles.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and all energy sources are locked out before mounting or removing the tool. Confirm the cylindrical shank is seated fully and clamped to the tool holder manufacturer's specified torque before spindle operation. Verify through-coolant passages are clear and coolant pressure is within the machine's rated range prior to running.
