The SIEG, short for Shanhei Industrial Company, is a tool manufacturer of the X1, X2, and X3 milling machines and the C0, C1, C2, C3, C4, C5, and C6 series of milling lathes.

The X series of mills has 3 models, the X1, X2, and X3. The X1 is commonly refered to as the Micro-Mill, the X2 is commonly referred to as the "mini-mill", and the X3 takes the title of "small-mill". This series is a small, manual, vertical milling/drilling machine designed for micro to light capacity applications. However, it should be noted that the manual operation can be converted to CNC operations through 3rd party modifications. The machine is not sold under the name SIEG but instead rebranded and sold by a variety of companies under the following names and product numbers: X1 aka the "micro-mill" = Harbor Freight 47158 X2 aka the "mini-mill" = Harbor Freight 44991, Grizzly G8689, Micro-Mark 82573, Homier 3947 and Cummins 7877. X3 aka the "small-mill" = Lathemaster ZAY7045FG, Grizzly G0463 and Harbor Freight 93885

The machine is popular among various hobby circles such as robotics, RC vehicles, modeling, model trains, and go carting. It has also found its way into shops where light capacity machining is required such as small engine repair. The reasons for its popularity is the tool can be cited as being cheap, light weight, and small enough to fit into an average garage without being intrusive. There are also many companies selling low cost upgrade parts.

This machine is the most popular of new generation of tools designed for the home enthusiast. One can now buy a 4 axis mill for less than $500 that will fit through a 32 inch doorway and is light enough to be picked up by one man and placed on a a workbench. This mill also has a sister device commonly called the "mini lathe".
