Tantung at Work

Still cuts at 1500°
  • Tantung blades will not anneal at 1500°F.
  • Maintains cutting edge hardness throughout tool life.
  • Longer tool life than HSS.
    		•  New life for older machines
  • Tantung can be used on machines where speeds and rigidity are limited.
  • With tantung tools, older machines can handle increased production loads and help reduce costs.
  • Performs interrupted cuts significantly better than carbides.
    		•

    Broad operating speeds
  • Tantung works at speeds of up to 450 SFPM.
  • Operates at speeds where HSS fails.
  • Effective at speeds where cemented carbides load-up.
  • Won't chip like carbides at lower speeds.

    Brinell hardness: 479 at 1200°F
    Transverse Rupture Strength
    300 x 10³ psi
