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.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.

  • shank


    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

  • tensile strength

    tensile strength

    In tensile testing, the ratio of maximum load to original cross-sectional area. Also called ultimate strength. Compare with yield strength.
