Nakanishi EMax EVOlution Micromotor Torque Motor, Twist HP & Foot Control

A complete benchtop micromotor system for jewelers who want high torque right at the handpiece without adding a reduction gear. Based on the NSK kit that educator Tonya Davidson uses for herself and recommends for her students, this special NSK EMax EVOlution kit pairs the high-torque ENK-250T motor with the IR-310 twist to open quick-change handpiece and a foot control. Tonya uses the IH-300 lever style handpiece in her kit but we offer this kit for those who prefer the twist to open IR-310 handpiece. See 134.602 for the lever style kit. The ENK-250T Torque Type motor delivers extra power that eliminates the need for an optional reduction gear, keeping the motor-to-handpiece length compact without sacrificing performance. NSK micromotors are trusted on the benches of the finest goldsmiths in the world, renowned for outstanding quality and all-day reliability.

The system delivers smooth, precise power either through the foot control or directly from the control box dial. With the foot control connected, you can choose between foot-operated set-point control or variable speed control. The IR-310 twist to open, twist-to-close mechanism allows for fast collet access without the need for wrenches or additional tools, keeping workflow smooth at the bench. This is a 120V unit. Not available for sale or shipment outside the United States and Canada.
