Tungaloy 6829498 Square-shoulder End Mill 1/2 in 1 Flute

Product Description

The TUNGALOY 6829498 is an indexable square-shoulder end mill designed for precision milling operations in metal-cutting environments. Built around the EPS cutter style, this tool accepts a single ASMT 11T3 series insert secured by a screw-lock method, delivering a 90-degree lead angle that produces true square shoulders on workpieces. With a 1/2-inch cutting diameter and a maximum depth of cut of 0.433 inches, it handles both slotting and peripheral milling in a range of materials. The 5/8-inch Weldon flat shank ensures positive, slip-resistant retention in standard end mill holders. This tool is installed and operated by machinists, tool-and-die professionals, and CNC setup technicians.

This end mill is suited for square-shoulder milling operations in job shop, production machining, and maintenance-repair environments. The single-flute, single-insert design is appropriate for applications requiring controlled chip load and precise shoulder geometry. With an overall length of 3.35 inches and a 1.0-inch head length, it fits standard spindle setups and is compatible with ISO tooling standards. No coolant-through capability is provided, so external flood or mist cooling should be used when cutting conditions require it.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Seat the Weldon flat shank fully into the holder and torque the set screw to the holder manufacturer's specification before operation. Insert indexing or replacement should be done with the tool removed from the spindle; use the appropriate Torx or hex key for the insert screw and inspect the insert pocket for debris before seating a new insert. Confirm runout with a dial indicator after securing the tool in the holder.
