Three typologies available from stock:

  • F.L.C. “free lock” for shaft or locked together
  • S.L.C. “self locking” with eccentric ring locking, to simplify the locking operation through an easy rotation of the anvil on the shaft itself.
  • M.L. “multi lock” with hose clamp and thread, unlike traditional anvils with thread locking, in the ML system the thread does not come out from the inside of the anvil (avoiding the damage of the shaft surface), and locks the bottom knife tightening the harmonyc steel clamps on the whole surface, guaranteeing a self centerning and mantaining the righ balance of the shaft.

The proprietary technology is based on a special support where a sintered steel cutting ring (HSS) is mounted that can be removed directly from the shaft through a specially designed omega “opening”. The ring has a double cutting edge and it can be used on both sides. The HSS grants an average lifetime of up to 4 times the normal steel. The revolution designed by Mario Cotta for your needs.
