Topas H.E.A.T. Extreme Double Layer Coated EDM Wire: SST is proud to offer bedra’s premier line of coated Electrical Discharge Machining wires. Extreme is the world’s first EDM wire available in 0.016” (0.4mm) Ø, and is outfitted with new and innovative coating technologies that have been optimized for Makino’s U6 H.E.A.T. Extreme Wire EDM machine.

topas H.E.A.T. Extreme – the world’s first 0.016” (0.4mm) Ø coated EDM wire!

SST Exclusive Wire to support Makino’s new U6 H.E.A.T. Extreme Machines and Technology

  • New High Speed Wire designed in cooperation with Makino for the U6 H.E.A.T. Extreme machine

  • New benchmark of productivity designated for various industries and applications seeking to achieve the fastest level of cutting speed
    • Cutting-off 3D printed parts
    • Difficult to machine alloys (nickel alloys for example)
    • Tall parts

  • Twice as fast as 0.010” (0.25mm) Ø brass wire with no increase in wire consumption rates

  • Helps reduce part cycle time while consuming less wire (lowers manufacturing costs)

  • New, innovative coating technology utilizes a unique hybrid zinc-enriched double layer that provides several machining benefits:
    • Achieve top cutting speeds
    • Reduced wire consumption rates
    • Prevention of wire breaks
    • Reliable Auto-Threading
    • Lower Manufacturing Costs
