Chris' Tips DISCONTINUED - This HiTorque Mini Mill has been replace by the 3990 HiTorque Mini Mill, Solid Column with Air Spring.You can compare the specifications for our mills.The LittleMachineShop.com HiTorque Mini Mill does not come with a drill chuck as many other mini mills do. That's because the drill chucks provided by the factory do not meet our quality standards (read: they're junk). We had them put the value of the drill chuck into other parts of the mill, like the large X-Y table that is unique to LittleMachineShop.com.
Get one of these drill chucks and you will be in business.Let's compare the LittleMachineShop.com Solid Column HiTorque Mini Mill to mini mills with a tilting column.
The tilting column on other folk's mini mills tilts 45 degrees from side to side. This has several advantages. First, it is possible to make some angled cuts. It's also easy to tram in the X-axis. One user (and only one) has described to me a cut that was impossible to make any way but using a tilting column.
This mill has a solid column. While it is harder to tram in the X-axis because you must use shims, it is not as easy to knock it out of tram as the tilting column mini mill. The solid column has thicker walls than the tilting column, and a stiffer joint where it joins the base, so the column is significantly more rigid than the tilting column.
LittleMachineShop.com no longer sells mills with a tilting column. That is an indication of how much better the solid column is.Here are data sheets for the machines that we sell.Here are the user's guides for our machines.Here's what you need to convert the HiTorque Mini Mill to CNC.
