iMX series Exchangeable Screw on Head connection features the World's first "Carbide Head"+"Carbide Holder" double face contact connection, according to Mitsubishi Materials' own research on exchangeable head end mills. But the company did not stop there.

Careful SWOT analysis of the conventional screw on head products indicated it was PARAMOUNT to re-engineer the carbide head joint connection for the next generation of Exchangeable head products to approach the performance of solid carbide end mills without encountering carbide joint failure due to tensile strength limitations of carbide threads.

Therefore, to overcome inherent tensile strength weakness of carbide threads, Mitsubishi Materials Engineers developed a process that enables a SPECIAL STEEL screw joint to be securely incorporated into the BOTH the CARBIDE HEAD and SHANK thus avoiding thread tensile failure common with ground carbide threads. The result for you is a highly reliable connection that can cope with high cutting loads and coolant thru head options.

In fact, the iMX connection was specifically designed to excel in high demanding heat resistant Aerospace applications were failure mode is typically attributed to joint rigidity resulting in run-out, deflection and poor tool life. The Economical iMX Series Exchangeable Screw on Head Ends are available in Coolant through and non-coolant configurations and will soon be your default solution to costly solid carbide end mill applications.
