The Nakanishi NSK EMax EVOlution Micromotor Basic Kit – Ring Style brings together three core components in a single professional package: the NE-249 Control Box, the ENK-410S Standard Micromotor, and the IR310 Ring Style handpiece. Trusted by goldsmiths and jewelers worldwide, NSK micromotors are recognized for exceptional build quality, smooth power delivery, and long-term reliability. The system operates at 1,000–40,000 RPM and supports both forward and reverse rotation. Speed can be set directly from the dial on the NE-249 Control Box, or—when paired with the optional foot control (sold separately)—via foot-operated set point control or variable speed control. The NE-249 features two motor inputs, allowing a second motor and handpiece to be added at any time. The ENK-410S motor is the most popular NSK motor among jewelers: slim, vibration-free, and highly reliable. The IR310 Ring Style handpiece features a twist-to-open, twist-to-close quick-change mechanism and is supplied with both 3/32" and 1/8" collets. This is a 120V unit. Not available for sale or shipment outside the United States and Canada.
