The LittleMachineShop.com HiTorque Mini Mill for sale is the best in its class. It has the most power, most torque, and a larger table than other mills in its class.
This mini milling machine has a solid column. It does not tilt from side to side. This construction is significantly stiffer than the tilting column on other mini mills. This model also includes the air spring head support for even support through the Z-axis range of travel.
The 500 Watt brushless spindle drive motor provides tremendous low-end torque. And you can vary the speed from 50 rpm to 2500 rpm continuously. There are no gears to shift. And, with no gears, the HiTorque Mini Mill is the quietest in its class.
The large mill table provides 50% more table area than other mini mills. It also has 30% more travel in each direction. The resettable feed dials allow you to zero them at any point.
The HiTorque mini milling machine for sale has drill press handles for drilling and fast motion of the mill's head. It also has Z-axis fine feed with 0.001" resolution for milling operations.
*NOTE* We ship machines only to the US and Canada.
Chris' Tips Here's Using the Bluetooth DRO Display.For more information on the Bluetooth DRO, visit the Bluetooth DRO Package page and the Android Tablet page.You can compare the specifications for our mills.Mini-Lathe.com has a review of our solid column mill.The solid column is much more rigid than the tilting column.
Some people may feel that the tilting column is a feature, but I have used a mini mill for 10 years and never tilted the column on purpose. 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.
