YG-1’s ENMX High-Feed Mill 4 is a series of small-diameter cutting tools for die/mold, power generation and other machining applications. The ENMX insert’s thickness allows normal flank wear to develop without encroaching on the secondary edge, resulting in the full use of all four edges, the company says. Thicker inserts also clamp more securely, the company says, ensuring predictable and secure machining and longer tool life in difficult applications. The thicker negative insert has a positive rake angle that improves chip evacuation and reduces machining load. The corner protection design is said further to enhance rigidity while increasing tool life in combination with the chipbreaker’s optimized geometry.

The ENMX cylindrical cutter is available in diameters ranging from 16 to 32 mm (0.75" to 1.25"). Shell mills are available in diameters ranging from 40 to 50 mm (1.5" to 2").


  • The Overhang Effect

    The length by which the tool extends from the toolholder is a variable that can be used to 'tune' the machining process. Contrary to what you may expect, increasing the tool's L:D ratio may reduce chatter and result in more productive milling.

  • Start With The Right Speeds And Feeds

    Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.

  • Machining Dry Is Worth A Try

    Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
