The LittleMachineShop.com HiTorque Micro Mill is the best in its class. It has the most power, the most torque, and a larger table than other mills in its class.

The 250 Watt brushless spindle drive motor provides tremendous low-end torque. And you can vary the speed from 100 rpm to 5000 rpm continuously. There are no gears or belts to shift. And, with no gears, the HiTorque Micro Mill is the quietest in its class.

The large mill table provides 50% more width than other micro mills. The resettable feed dials allow you to zero them at any point.

The HiTorque Micro Mill has a drill press handle for drilling. It also has Z-axis fine feed with 0.001" resolution for milling operations.

This is a version of the SIEG SX1P micro milling machine.

You can compare the specifications for our mills.

Here are the user's guides for our machines.

These machines are fully assembled, adjusted, and tested at the factory. Then the column and head is removed from the base so they can ship in two components. This reduces the shipping cost by about half.

When you get the machine, use the four bolts provided to fasten the column to the base and you are ready to go. The manual has complete instructions.
