Promax D6446370/12 Square End Mill

Product Description

The PROMAX D6446370/12 is a square end mill designed for precise milling operations in metalworking and machining applications. Square end mills produce flat-bottomed slots, pockets, and profiles with sharp 90-degree corners. This tool is suited for use in CNC machining centers and manual milling machines alike. It features a standard variable helix designation of No, indicating a conventional helix geometry. At 0.2 pounds, the tool is lightweight and straightforward to handle during setup and changeout. Machinists and tool-and-die professionals are the primary users of this cutting tool.

This square end mill is used in job shops, production machining environments, and maintenance repair operations where flat-bottom cuts, shoulder milling, and full-slot milling are required. It is appropriate for ferrous and non-ferrous materials depending on substrate and coating specifications. Sold individually with a minimum order quantity of one piece, making it accessible for single-tool replacement or low-volume procurement.

Installation Notes

Installation of end mills should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the machine is in a locked-out, tagged-out state before changing tooling. Use the correct collet or tool holder to achieve proper runout and secure clamping before commencing any cutting operation. Follow the machine manufacturer and tooling manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
