With the goal of making an easier and safer tooth installation system, MTG has developed MTGtwist, a hammerless tooth fixing solution. This system works with MTGtwist enhanced CAT-style teeth and is compatible with existing CAT-style adapters.
MTGtwist
Simply Turn The Pin With The Removal Tool
THIS MEANS THERE IS ABSOLUTELY NO NEED FOR HAMMERING!

When in operation impact to the tooth will not cause the pin to turn. It cannot detach because it has excellent retention.
Advantages
Safety: as no hammer means no accidents due to hammering or flying particles.
Comfort: the effort required to change the teeth is much less than with the hammer.
Reduced Cost: one person can change the tooth.
Safer retention: its excellent retention avoids the risk of tooth loss.
Applicable to present adapters: you can use MTGtwist with standard adapters at no additional cost.
Pin re-use: Rugged and does not suffer during assembly and disassembly. It can be re-used in most cases.
Reliability: tested during two years in machines all over the world.
